@hacksenwerk

Some years ago, when ALSA backend was removed from Firefox, you had to
1. compile apulse,
2. configure ALSA mixer (with arateconf),
3. allow ALSA sound device in Firefox's sandbox config.

Today it is more simple. You have to
1. install apulse from Devuan repo,
2. configure ALSA mixer (with arateconf).
! You do not need to configure sandbox for apulse.

HYPOTHESIS: Perhaps, it might be possible to use microphone with Firefox's ALSA backend without apulse.
What might be needed is to set

security.sandbox.content.read_path_whitelist                /dev/snd/
security.sandbox.content.write_path_whitelist               /dev/snd/

in about:config

See, for example:

You won't have sounds on firefox, do you ?

Playback in Firefox works without problems with ALSA (without pulseaudio and pipewire).
Sound quality is good, because fftrate ALSA plugin is installed and enabled (with ALSA config).

NOTE: If you want to use Firefox for video conferences, you have to run it with apulse:

$ apulse firefox

It works without problems, if ALSA software mixer is configured with arateconf.
If you are an ALSA expert, you may try to create ALSA config without the help of arateconf.

EDITED

BEFORE running "arateconf", you should close all audio applications.
The "TEST" function of "arateconf" will fail, if your "audio device" is already in use.
When pulseaudio and pipewire are removed, you can easily free your "audio devices" with "fuser".
For example:

$ fuser -av $(find /dev/snd -type c 2>/dev/null)
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  igor       2261 F.... mate-settings-d
                     igor       2310 F.... mate-volume-con
/dev/snd/pcmC0D0c:
/dev/snd/pcmC0D0p:   igor       8248 F...m firefox-esr
/dev/snd/seq:
/dev/snd/timer:      igor       8248 f.... firefox-esr 

"mate-settings-daemon" and "mate-volume-control-status-icon" need not to be killed.
But "firefox-esr" should be killed to free the "audio device":

$ fuser -ikv $(find /dev/snd -type c 2>/dev/null)
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  igor       2261 F.... mate-settings-d
                     igor       2310 F.... mate-volume-con
Kill process 2261 ? (y/N) n
Kill process 2310 ? (y/N) n
/dev/snd/pcmC0D0p:   igor       8248 F...m firefox-esr
Kill process 8248 ? (y/N) y
/dev/snd/timer:      igor       8248 f.... firefox-esr
Kill process 8248 ? (y/N) y
Could not kill process 8248: No such process

$ fuser -av $(find /dev/snd -type c 2>/dev/null)
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  igor       2261 F.... mate-settings-d
                     igor       2310 F.... mate-volume-con
/dev/snd/pcmC0D0c:
/dev/snd/pcmC0D0p:
/dev/snd/seq:
/dev/snd/timer: 

Now, when audio devices are free, you can run "arateconf".

if i press "T", there is "failed".

Input:

It failed to open "Input", because you configured your "Cambridge USB DAC" for recording.
"DAC" means "digital-to-analog converter",
see _https://en.wikipedia.org/wiki/Digital-to-analog_converter.
As the name suggests, it is not supposed to be used to record "analog sound".

For "Output", you also got an error message:

Set format 'S32_LE' ... Unsupported!

It means that your Cambridge DAC does not support 'S32_LE' (it is now default for playback),
or ALSA driver (snd_usb_audio) for your USB DAC does not support 32bit.
Try 'S16_LE', or else.
Read the manual again and change 'S32_LE' to 'S16_LE'.
Press "F" to change "format".

======================
|  Sound parameters  |
----------------------
S - Sample rate = 48000 Hz
C - Channels    = 2

Your Intel HDA codec (Generic_1) does support 48kHz 32bit.
It should also support 192kHz 32bit.
This may provide much better sound quality than your "Cambridge DAC" (it is likely to be 48kHz 16bit and nothing more with ALSA).
You can test different "sample rates" and "formats" with "arateconf".

You can also check your "proc" (cards, hw_params), for example:

$ cat /proc/asound/cards

                      Griffin Technology, Inc iMic USB audio system at usb-0000:00:1a.0-1.3.4, full s

period_size: 1920
buffer_size: 7680

NOTE: "arateconf" is simply a tool to configure ALSA,
that is, a tool to generate an ALSA config file "~/.asoundrc".
It takes data from ALSA and from Linux (proc, etc.).

Notable Realtek products include ... audio codecs (AC'97 and Intel HD Audio ).
_https://en.wikipedia.org/wiki/Realtek#Notable_products

ALSA detected an Intel HDA codec on your motherboard. It has a "generic driver" for it.
It should work without problems.
You may select Intel HDA codec as default for recording.
If you connect new USB audio devices, you have to create a new ALSA config with "arateconf".

@kapqa

Pulseaudio is not a driver. It is, rather, a sort of malware.

XFCE is buggy and crappy, and it does not support "alsa-only".

The best solution might be Devuan MATE Desktop (without pulseaudio and pipewire).
It works without problems even on very old computers (such as those of 2001).
Although, of course, web browsers are rather slow on very old computers.

If an UCM configuration is present for a card then pulseaudio will ignore the built-in profiles and generate a profile based on the UCM files.

...
1. Disable PulseAudio or PipeWire so ALSA UCM is not active at all.

This may mean, perhaps, that you do not need ALSA UCM, if you are not using PulseAudio and PipeWire.

Therefore, the workaround from stackoverflow may fix the problem.

sudo /usr/sbin/alsactl --debug restore

sudo /usr/sbin/alsactl --debug --no-ucm restore 

Or you can simply ignore the "error" message, which is, in fact, just "warning", not "error".

EDIT:

If I understood you correctly, your ALSA was almost silent.
The "force-reload" of ALSA seemed to fix the problem.

Since ALSA UCM is not needed, you may simply ignore the "warning" message, and see how it works.

NOTE: OSS4 is much more louder than ALSA with the same sound card.
The fftrate ALSA plugin makes ALSA louder, but not as loud as OSS4.
Most important, the fftrate improves the sound quality of ALSA, although, of course, I like more the sound of OSS4.
If you are content with the sound quality of ALSA, you may use it as is.
But if you need to configure a software mixer for ALSA (e.g., for video conferencing), it might be a difficult task (without the fftrate plugin).

@kapqa

"alsa-only" means that you may need some Linux commands.

To reload ALSA on Devuan, you can use alsa-utils.

The Devuan default is "SysV init"

$ /sbin/init --version
SysV init version: 3.06 

If you are using "SysV init", you can reload ALSA with this command:

$ sudo /etc/init.d/alsa-utils force-reload
Shutting down ALSA...done.
Setting up ALSA...done. 

"soft restart":

$ sudo /etc/init.d/alsa-utils restart
Shutting down ALSA...done.
Setting up ALSA...done.

$ sudo /etc/init.d/alsa-utils stop
Shutting down ALSA...done.

$ sudo /etc/init.d/alsa-utils start
Setting up ALSA...done. 

Another useful command is fuser

$ fuser -av $(find /dev/snd -type c 2>/dev/null)
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  igor       2328 F.... mate-settings-d
                     igor       2382 F.... mate-volume-con
/dev/snd/pcmC0D0c:
/dev/snd/pcmC0D0p:   igor       2843 F...m firefox-esr
/dev/snd/seq:
/dev/snd/timer:      igor       2843 f.... firefox-esr 
PID 2328 /usr/bin/mate-settings-daemon
PID 2382 mate-volume-control-status-icon
PID 2843 /usr/lib/firefox-esr/firefox-esr 

"mate-volume-control-status-icon" is MATE volume control applet.
It works with ALSA in "alsa-only" mode (as well as "mate-settings-daemon").
However, after removal of pulseaudio, you have to reload ALSA, or reboot the system.

@kapqa

The solution to Linux sound problems is rather straightforward:
1. remove pulseaudio;
2. install and configure fftrate ALSA plugin.

It seems that many Debian users have already removed pulseaudio,
but nobody has compiled fftrate, although it is very simple.

There is a conspiracy theory that pulseaudio and pipewire are destroying human brain by "harmful frequencies".

You may ask golinux to compile deb packages of fftrate for you.
He has Chimaera (oldstable) and, therefore, can install gcc-10 and g++-10 from the standard Chimaera repositories (that is, Devuan's oldstable repositories).
This also means that gcc-10 is the default compiler for Chimaera, and he does not need to configure "make" (./fftrate/src/lib/makedef.mk ) for gcc-10.
The fftrate deb-packages, which were compiled on old Debian/Ubuntu distros, also work on new Debian/Ubuntu (and Devuan) versions without problems.

Daedalus 5.0 is the current stable release.
Chimaera 4.0 has moved to oldstable status.

If it is "annoying behaviour" for you, it does not mean that it is also annoying for others.
Since nobody complains, it might be the normal way of things for pulseaudio users.
Although, of course, it might be a security problem.

Umask
_https://en.wikipedia.org/wiki/Umask
_https://wiki.archlinux.org/title/Umask

$ umask
0022 

_https://www.linuxquestions.org/questions/linux-general-1/mounting-ntsf-drive-in-fstab-unsure-of-fmask-and-dmask-values-4175458533/#post4934200

fmask, dmask, and umask taken together pertain only to Windows filetypes ( NTFS and FAT32 ) whereas umask alone pertains to both windows and Linux filetypes but are implemented 2 different ways.

On Linux Filesystems

At the moment of birth every file has permissions of 666 and every directory has permissions of 777. A system wide umask is created to modify these permissions immediately after birth and it's currently set at 002. So when you create a new file it's permissions are:

666
002 <-- minus the umask
==
664

And every new directory has permissions of:

777
002 <-- minus the umask
==
775

On Windows Filesystems

Windows fileystems have no Linux file permission attributes so a virtual filesystem is used to create a "view" to give them the appearance that they do have them. The system wide umask has no affect on these filesystems nor does a chmod or a chown. They can only be set when the "view" is created in fstab.

At the moment of birth NTFS files and folders start out with exactly the same permissions: 777. If you were to set up in fstab a umask of 002 for these partitions then the result would be different from a Linux filesystem:

File: 777 - 002 = 775
Folder: 777 - 002 = 775

The folder setting is fine and that's the way you want them to be but the files have all been made executable - every single one of them. You can change that by separating umask into it's constituent parts: fmask and dmask:

So if you set up fstab this way for an NTFS partition: dmask=002,fmask=113

File: 777 - 113 = 664
Folder: 777 - 002 = 775

When you insert a USB drive, it is automatically mounted to a directory under /media
However, if your USB drive has a Windows file system (e.g. NTFS, or exFAT), all your text files (and all other files: *.jpg, *.wav, etc.) on the USB drive become executable (777 - 022 = 755).
If you copy such files to your home folder, you have to fix permissions, for example:

$ chmod -Rv -x+X -- ./ 

_https://unix.stackexchange.com/questions/296967/how-to-recursively-remove-execute-permissions-from-files-without-touching-folder

It seems that this problem can be easily fixed with /etc/udisks2/mount_options.conf

$ ls -1 /etc/udisks2/
mount_options.conf.example
udisks2.conf 

$ sudo nano /etc/udisks2/mount_options.conf
 
$ cat /etc/udisks2/mount_options.conf
[defaults]
vfat_defaults=uid=$UID,gid=$GID,shortname=mixed,utf8=1,showexec,dmask=022,fmask=133
exfat_defaults=uid=$UID,gid=$GID,iocharset=utf8,errors=remount-ro,dmask=022,fmask=133
ntfs_defaults=uid=$UID,gid=$GID,dmask=022,fmask=133 

NOTE: /etc/udisks2/mount_options.conf is enabled automatically (a reboot is not required).
You can simply insert your USB drive and check file permissions:

$ touch file.txt
$ stat -c %a file.txt
644
$ mkdir folder1
$ stat -c %a folder1
755 

See:
_https://chmodcommand.com/chmod-644/
_https://chmodcommand.com/chmod-755/

Perhaps, this mount_options.conf can be somehow improved, or there is a better solution.

Thank you for the link.

Have you already tried to build it?

If you really need it, you may start a new topic: "How to install the newest version of scrcpy?"

And 40 minutes after that, the FBI had Thomas's Samsung Android smartphone unlocked and open for detailed inspection of the shooter's social media, browsing, texting, whatever, history.
What's interesting is that in other, just it was coincidental really, reporting, it appears to be fortuitous for the FBI that Thomas was not using a later model Apple iOS device since some documents leaked from Cellebrite indicate its inability to unlock such devices. 9to5Mac picked up on this last Thursday, reporting under their headline "Cellebrite cannot unlock most iPhones running iOS 17.4 and later." They wrote: "Leaked documents reveal that Cellebrite cannot unlock iPhones running iOS 17.4 and later, at least as of the date of publication," which was April of this year. They said: "The company has confirmed that the documents are genuine. Cellebrite devices, which are widely used by law enforcement agencies, can crack most Android phones, though there are exceptions.

How to rebuild scrcpy for Devuan.

Install the tools "which are considered essential for building Debian packages":

sudo apt install build-essential debhelper devscripts 
sudo apt install apt-file command-not-found 

Debian wiki: apt-file
_https://wiki.debian.org/apt-file

NOTE: If apt-file doesn't help, you may try to search with Google, for example:

"/usr/lib/android-sdk/build-tools/debian/dx" site:packages.ubuntu.com 
https://www.google.com/search?&q=%22%2Fusr%2Flib%2Fandroid-sdk%2Fbuild-tools%2Fdebian%2Fdx%22+site%3Apackages.ubuntu.com 

Install android-sdk and default-jdk

sudo apt install android-sdk default-jdk

dalvik-exchange is also missing (it is in the same Ubuntu repository)

dalvik-exchange_10.0.0+r36-4_all.deb	    2022-04-30 
http://us.archive.ubuntu.com/ubuntu/pool/universe/a/android-platform-dalvik/dalvik-exchange_10.0.0+r36-4_all.deb

Notice that "android-platform-dalvik" is the name of the source.
The folder "android-platform-dalvik" contains the source packages and the binaries.
This is how to search for missing packages.

Download and install dalvik-exchange

sudo dpkg -i dalvik-exchange_10.0.0+r36-4_all.deb

Download and install 3 packages of "android-framework-23" from the same repository.

android-sdk-platform-23
_http://us.archive.ubuntu.com/ubuntu/pool/universe/a/android-framework-23/android-sdk-platform-23_6.0.1+r72-6_all.deb

./scrcpy-dbgsym_1.25-1_amd64.deb
./scrcpy-server_1.25-1_all.deb 

7. Install the packages

sudo dpkg -i scrcpy_1.25-1_amd64.deb scrcpy-server_1.25-1_all.deb 

You may also try to build the sources from Debian unstable:

_https://packages.debian.org/source/unstable/scrcpy
Download scrcpy
scrcpy_1.25-1.dsc   
scrcpy_1.25.orig.tar.gz   
scrcpy_1.25-1.debian.tar.xz

NOW WE KNOW WHERE TO SEARCH FOR MISSING PACKAGES.

The reference package:

scrcpy_1.25-1_amd64.deb	        2023-01-21 
http://us.archive.ubuntu.com/ubuntu/pool/universe/s/scrcpy/scrcpy_1.25-1_amd64.deb 

It is a native Debian package (without "ubuntu" mark) of 2023.

Ubuntu Maintainers Handbook:
When Ubuntu adds a change or modification on top on what is in Debian, that change is expressed in the version number. One can think of a version number consisting of three segments: [upstream_version]-[debian_revision]ubuntu[ubuntu_revision]. The - splits the upstream version from the Debian packaging segment as you have seen in Debian control field "Version". The ubuntu string then marks that whatever follows it is related to changes added in Ubuntu.
_https://github.com/canonical/ubuntu-maintainers-handbook/blob/main/VersionStrings.md

Of course, you can simply download the native Debian packages and install them. But they may work better, if they are rebuilt for Devuan. You can also rename the package, disable a sort of pulseaudio, remove systemd dependencies, etc.

Some packages should be rebuilt because of libc6 and/or other dependencies.

#18 Re: Desktop and Multimedia » [SOLVED] Android -> Linux screen mirroring software » 2024-07-28 15:11:50

If you do not want learn yourself, you can only hope that others may learn how to rebuild packages. Otherwise, it might be nothing to install.

There is an official Ubuntu repository with native Debian sources and native Debian packages which work with Devuan. If some of them are needed to build Devuan packages, why not import them to the Devuan repository?

#19 Re: Desktop and Multimedia » [SOLVED] Android -> Linux screen mirroring software » 2024-07-28 09:00:41

This means that you have to learn how to rebuild packages.
But you cannot learn this, if it is impossible to compile.

On the other hand, if the users do not want to learn anything, the "under-staffed and over-worked Devuan crew" may have more work to do.

Have you already installed android-sdk-platform-23 and rebuilt scrcpy for Devuan?

The name of a Debian package is determined by its changelog.
If you want to change the name, you can add certain lines to the changelog, or edit it.

As the names suggest, all these debs are native Debian packages, which were somehow appropriated by Ubuntu.

The native Ubuntu packages look like this:

android-sdk-platform-23_6.0.1+r72-6ubuntu1_all.deb

android-sdk-platform-23 is needed to compile scrcpy on Devuan 5 Daedalus (see above).

The source is android-framework-23

android-framework-23_6.0.1+r72-6.dsc	         2021-01-02

The "unstable" source failed

dpkg-checkbuilddeps: error: Unmet build dependencies: android-sdk-platform-23
$ dpkg-buildpackage -us -uc -b

EDIT:
Debian sources need "android-sdk-platform-23" to be compiled.
But it seems that it is not available for Debian 12 Bookworm and Devuan 5 Daedalus.
This is the problem.

Thank you for the link!
It has links to old and new sources.

I will try to compile this:

_https://packages.debian.org/source/unstable/scrcpy
Download scrcpy
scrcpy_1.25-1.dsc   
scrcpy_1.25.orig.tar.gz   
scrcpy_1.25-1.debian.tar.xz

But I do have any sort of Android.

In the Chimaera repo, there might be the same source as in Debian

Debian:
_https://packages.debian.org/bullseye/scrcpy

Download Source Package scrcpy:

    [scrcpy_1.17-1.dsc]
    [scrcpy_1.17.orig.tar.gz]
    [scrcpy_1.17-1.debian.tar.xz]

These three packages are needed. They provide the original source code, Debian patches, etc.
The Chimaera repo is likely to have these 3 packages and, perhaps, a package with Devuan patches.

Patches will automatically be applied, when you run "dpkg-source -x *.dsc"

How to get source code of package using the apt command on Debian or Ubuntu
_https://www.cyberciti.biz/faq/how-to-get-source-code-of-package-using-the-apt-command-on-debian-or-ubuntu/

1. enable the source repo
2. download the source with apt-get

apt-get source scrcpy

apt-get will download the source packages, unpack the source, and apply the patches.

3. disable the source repo
4. install build dependencies with mk-build-deps
5. build the package
