#1 Re: Desktop and Multimedia » High CPU by PulseAudio » 2020-08-11 19:31:08

Hi

And as professionel I am using jack for most of this when it really matters. It reduces latency together with alsa, which in that situation is the most important thing. I also think using pulseaudio is much simpler for the programmer, because he does not need to take care of a lot of small details. But on high end gear I can hear a difference between pulseadio and alsa because of the higher latency.

Hi again

We can help the best if you are using devuan repos only. If you install programs from other places they might very well be configured with both systemd, pulseaudio, libraryversions and other things that are not compatible with devuan. So be careful when you do that. If things work to your satisfaction then fine (using a bit of cpu sounds like an acceptable compromise). But take care when upgrading. You might break your system in the process.

Hi

It looks like you get sound working ;-)

I am a professional musician myself using my setup for everything. And I have removed all of pulseaudio. Using firefox, vlc, mpv, audacity, musescore with just alsa. And for professional work I use jack as audioserver.

Make sure your /etc/pulse/client.conf.d/00-disable-autospawn.conf looks like this:

# On linux systems, disable autospawn by default
# If you are not using systemd, comment out this line
autospawn=no

Then you should be safe that pulseaudio is not working. If you find any problems then try uninstall and purge pulseaudio with apt purge pulseaudio. Then apt will also remove pulseaudio configuration files (that might be your problem)

No

Do not be afraid. This is a the manual way to do this and by the way Head_on_a_Stick is a very reliable person. And it will not in any case break something that is not allready broken ;-() But more likely fix it ;-))))))))

Hi

Do you have multiple soundcards ??. Take a look with "alsamixer" in a terminal. F6 will allow you to choose and set your default soundcard. You can also choose soundcard in volumicon by right clicking and choose preferences. Hopefully this is your problem. If not we have to look a littel deeper. But the simple things first ;-))

Hi

Maybe try this https://dev1galaxy.org/viewtopic.php?id=3732 Howto disable pa see here https://dev1galaxy.org/viewtopic.php?id=3728 . And here do the opposite of what is suggested

Dont use pulseaudio

In most situations you do not need pulseaudio. Just use alsa instead. This will reduce latency and overhead.

Alsa is enabled by default. Volume and audio device can be choosen and adjusted in a terminal using the command "alsamixer".
If you want to adjust with a gui install volumeicon-alsa from a terminal with "apt install volumeicon-alsa" as root. Add it to your desktop startup (howto depend on the enviroment). But it can also be started from a terminal using the command "volumeicon" Right click the voulmeicon to configure preferences.

And that should be about it.

Yes. This is my opinion as well. Devs and administrators should decide what i relevant and needed. The suggestion is to have a small goldmine of solutions and hacks of general interest and most common questions.

What about

"Devuan workaround wiki"

It could over time contain quite a lot of stuff. Systemd related. How to avoid unneeded services. Upgrade solutions. And many others.

#10 Re: Installation » backports » 2020-07-29 21:53:31

Hi

It has no effetct until you want to install something in backports. You are doing this by telling apt to use backports with "apt install -t beowulf-backports something".

#11 Re: Documentation » HOWOTO: Beowulf LXQt post installation tweeks » 2020-07-27 18:02:04

Hi

You may be right about that one. But it can be solved by enviroment variables ;-)). For serious sound I am using jack anyway. Pulseaudio  and jack are no good to  use at the same time. But that is offcourse my special case.

How about autoselecting the non-HDMI output for laptops? ALSA doesn't do that.

(Sorry for the OT, OP.)

#12 Re: Documentation » HOWOTO: Beowulf LXQt post installation tweeks » 2020-07-27 16:10:27

Hi

I hope FTW is not meant in a bad way :-)) . I simply consider pulseaudio i plague like systemd. And I have seen no arguments for the opposite. I am a professional musician and like everyone to have the best possible sound. And I can hear a difference for the better when pulseaudio is  not used ;-))

You really need to put as your signature.

"volumeicon-alsa FTW!"

I like my hardware controls for alsa, well i have to using dwm..

#13 Re: Desktop and Multimedia » xfce4-alsa-plugin now available for Debian-based systems (0.3.0-2) » 2020-07-27 14:17:15

Or use volumicon-alsa if you want a graphical application

#15 Re: Documentation » HOWOTO: Beowulf LXQt post installation tweeks » 2020-07-27 08:12:00

Hi

Will just mention that instead of enabling pulseaudio. Witch is software only and adding overhead and latency to your system, you can install volumeicon-alsa instead and add it to your desktop startup.

#16 Re: Devuan » Thanks Devuan Developers » 2020-07-22 21:52:35

Hi

To me it was no joke but true. Sysvinit is slower at boot than systemd. But it is smarter and simpler and more reliable in so many other ways ;-))

#17 Re: Installation » [IDEAS] Rollback system in Devuan » 2020-07-22 16:22:57

Hi

Use btrfs. As long you do what the debian wiki suggest you should be very safe https://wiki.debian.org/Btrfs . Snapshots takes very little space (and time). I hav been using btrfs for a long time. I have used compression but today I am using it without. It makes it a lot faster and avoids trouble.

#18 Re: Hardware & System Configuration » WiFi Question » 2020-07-07 08:31:42

Hi

I think your wifi is never than the 4.19 kernel. So it is not supported by that. You can try the following http://ubuntuhandbook.org/index.php/201 … ntu-19-04/ or install a never kernel from backports.

#19 Re: Installation » Errors encountered processing: libgstreamer-gl1.0-0_1.14.4-2_amd64.deb » 2020-07-07 08:27:07

Hi

I am sorry to say this. You have a FrankenDevuan in your sources list. Apt (aswell apt-get and aptitude) cannot solve the dependencies with this. Deb-multimedia is a no go. They rebuild a lot of debians packages. And they are not compatible with Devuan. They are also a problem in pure Debian if you are doing anything special. Remove anything but devuan from your sources list. And if you are lucky a very necessary downgrade as suggested by Head_on_a_Stick  will solve most problems.

#21 Re: Other Issues » [Solved] linux-5.6.0-0.bpo.2 stucks at "waiting for /dev.... udevd" » 2020-07-05 19:13:45

Hi

Maybe frankenDevuan maybe not. Maybe try to remove openrc (and use the default sysvnit) instead. I have had problems with openrc on devuan. Not the case with sysvinit. And what rules did you apply to /etc/udev/rules.d/51-android.rules ??? . How are your /etc/apt/sources.list  and other files from there.
It is difficult to help because we don't know what you have done in your editing. And why are you using the kernel form unstable instead from backports. And why not 4.19 that you report works just fine.

I have one rule. If it works don' t break it. Seems to me you are making some of the problems yourself. I am sure we will like to help you. But try not to mess with things. Use packages from only one distro and release (Beowulf). Do not blend them that will just make more problems.

#22 Re: Hardware & System Configuration » PnP USB Audio Device doesn't work » 2020-07-01 20:59:03

Hi

Happy that you got things sorted out (sort of). The developers knows about the audio problem but they cannot fix everything debian is doing in a bad manner. But all you needed to know is stated in the release notes. The easy way to deal with pure alsa in a gui is as have said many times to install volumicon-alsa and add it to your desktop startup.

#23 Re: Hardware & System Configuration » PnP USB Audio Device doesn't work » 2020-07-01 11:32:39

Hi

What does "aplay -l" say ???  And as well "cat /proc/asound/cards" ?? For me it looks like, enabled or not, that linux sees your intel device.

Have you tried with pulseaudio enabled (see devuan release notes for howto enable it).

Have a nice day

#24 Re: Hardware & System Configuration » PnP USB Audio Device doesn't work » 2020-07-01 10:05:59

Hi again

That's is just fine. But in many cases the volume is muted so you cant hear anything. This is because most programs defaults to pulseaudio. You can try what i suggested above, or read in the relesenotes howto enable pulseaudio.

Have a nice day
Lars H

#25 Re: Hardware & System Configuration » PnP USB Audio Device doesn't work » 2020-07-01 09:49:43

Hi

Does your audio work. Try using alsamixer in a terminal. With that you can choose device and set the volume. Pulseaudio is not the default in Devuan. But if alsa works install volumeicon-alsa and add it to your desktop and your done. It works

Have a nice day
