Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

Post the output of this commad:

ls -1 /usr/share/alsa/ucm2/USB-Audio/Behringer

If it is in the list, it is supported.

If not, you may try to compile:

$ apt source alsa-ucm-conf --simulate

$ ls -1 /usr/share/alsa/ucm2/USB-Audio/Behringer
Flow8-Recording.conf

UMC204HD-HiFi.conf
UMC404HD.conf
UMC404HD-HiFi.conf

It looks like all three are supported with HiFi output in Devuan Excalibur...

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

alsaucm: error failed to open sound card U192k: No such file or directory

It is not connected.

Check

cat /proc/asound/cards

It might be a hotplug issue. Try unplugging and plugging the device back in, then check

cat /proc/asound/cards

When the card was connected, the command

amixer -c U192k controls

printed mixer controls for it, including inputs (mic).

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

It is still connected:

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

Do you want to enable HiFi profile?

alsaucm reload

alsaucm -c U192k list _verbs

alsaucm -c U192k set _verb HiFi

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

Hmmm. I ran

$ alsaucm reload

No complaints. However, the next command didn't work. Unfortunately I didn't copy the result down. I then rebooted and this is the result:

$ alsaucm reload
ALSA lib parser.c:244:(error_node) UCM is not supported for this HDA model (HD-Audio Generic at 0xd05c8000 irq 81)
ALSA lib main.c:1554:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6
alsaucm: error failed to open sound card hw:0: No such device or address

Suddenly, the Behringer card is in the wrong order priority, despite the ~/.asoundrc file supposedly setting the Behringer card to default:

$ cat /proc/asound/cards
 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd05c8000 irq 81
 1 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd05c0000 irq 82
 2 [U192k          ]: USB-Audio - UMC404HD 192k
                      BEHRINGER UMC404HD 192k at usb-0000:08:00.3-1, high speed

I then tried unplugging and replugging the Behringer card, but still nothing:

$ alsaucm reload
ALSA lib parser.c:244:(error_node) UCM is not supported for this HDA model (HD-Audio Generic at 0xd05c8000 irq 81)

                      HD-Audio Generic at 0xd05c8000 irq 81
 1 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd05c0000 irq 82
 2 [U192k          ]: USB-Audio - UMC404HD 192k
                      BEHRINGER UMC404HD 192k at usb-0000:08:00.3-1, high speed

Will try another restart.

Nothing returned.

Not sure what is going on. Please advise.

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

You have the correct UCM config files (UMC404HD.conf, UMC404HD-HiFi.conf) in place — but ALSA UCM is not loading them because the card name U192k does not match the expected directory structure.

UCM expects:

/usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD.conf

But your files are in:

/usr/share/alsa/ucm2/USB-Audio/Behringer/UMC404HD.conf

Fix:
Create a symlink so UCM finds the config:

sudo mkdir -p /usr/share/alsa/ucm2/conf.d/USB-Audio
sudo ln -s /usr/share/alsa/ucm2/USB-Audio/Behringer/UMC404HD.conf \
  /usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD.conf
sudo ln -s /usr/share/alsa/ucm2/USB-Audio/Behringer/UMC404HD-HiFi.conf \
  /usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD-HiFi.conf

Then reload:

sudo /etc/init.d/alsa-utils force-reload

Test:

alsaucm -c U192k list _cards

No dice.

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

see above _https://dev1galaxy.org/viewtopic.php?pid=61493#p61493

ALSA UCM2 expects the configuration to be in /usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD.conf when using the modern conf.d scheme.

From the official ucm.conf and documentation:

UCM2 uses conf.d/${CardDriver}/${CardLongName}.conf as the primary lookup path.
Your card’s driver is USB-Audio, so UCM searches in conf.d/USB-Audio/.
Even though you have UMC404HD.conf in /usr/share/alsa/ucm2/USB-Audio/Behringer/, it won’t be found unless symlinked into conf.d/USB-Audio/.

On Deadalus, the folder /usr/share/alsa/ucm2/conf.d/USB-Audio already exists, but it has only one file inside

$ ls /usr/share/alsa/ucm2/conf.d/USB-Audio 
USB-Audio.conf

$ file /usr/share/alsa/ucm2/conf.d/USB-Audio/USB-Audio.conf
/usr/share/alsa/ucm2/conf.d/USB-Audio/USB-Audio.conf: symbolic link to ../../USB-Audio/USB-Audio.conf

Try to create symlinks so UCM finds the config:

sudo ln -s /usr/share/alsa/ucm2/USB-Audio/Behringer/UMC404HD.conf \
  /usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD.conf
sudo ln -s /usr/share/alsa/ucm2/USB-Audio/Behringer/UMC404HD-HiFi.conf \
  /usr/share/alsa/ucm2/conf.d/USB-Audio/UMC404HD-HiFi.conf

Then reload ALSA

sudo /etc/init.d/alsa-utils force-reload

Now alsaucm -c U192k list _cards may work.

Re: Behringer UMC204HD with Devuan Excalibur install and Alsa.

Alsa refuses to cooperate:

$ alsaucm -c U192k list _cards
ALSA lib main.c:1554:(snd_use_case_mgr_open) error: failed to import U192k use case configuration -2
alsaucm: error failed to open sound card U192k: No such file or directory

The sound card is now default again:

$ cat /proc/asound/cards
 0 [U192k          ]: USB-Audio - UMC404HD 192k
                      BEHRINGER UMC404HD 192k at usb-0000:08:00.3-1, high speed
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd05c8000 irq 81
 2 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xd05c0000 irq 82

The symlinks appear to be correct:

$ ls /usr/share/alsa/ucm2/conf.d/USB-Audio/
UMC404HD.conf  UMC404HD-HiFi.conf  USB-Audio.conf
