Problem with ALSA Sound – No Sound After Updating anti-X

To be honest, I have no idea.

I have searched for both ‘alsa’ and ‘ucm’ on my PC:

find / -mount -iname '*<searched term>*'

The ‘ucm’ directory is indeed present ‘/usr/share/alsa/ucm/’ but I do not know if it messed the setting up.
The ‘alsaucm’ utility (according to its man-pages) is expected to help setting up “complex sound cards”.
I have never heard of it before.
Did you try it (‘alsaucm -i’)?

Some thoughts.

Do you have libasound2-plugin-equal?

Try deleting the ~/.asoundrc (make a backup) file, reboot.

If you don’t have ~/.asoundrc, you might need one.

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.

I tried the antiX 19 LiveCD. The sound works fine with the LiveCD.

That proves your hardware is OK and the shipped /etc/asound.conf is OK

I just updating anti-X and no I cannot hear any sound.

This can be caused by playing music/sounds while simultaneously conducting an update.

Make sure libasound2-plugin-equal is installed
Run this command (using sudo might not be required)
sudo aplay /usr/share/sounds/alsa/Front_Center.wav

If the command returns something similar to this

ALSA lib pcm_equal.c:236:(_snd_pcm_equal_open) Problem with control file .alsaequal.bin.
aplay: main:788: audio open error: Operation not permitted

Where would this extra ucm directory be located? Can you give me a full path?

re: RobK88 – where is the /ucm directory?

I believe it is always a subdirectory within /alsa.

The location of alsa might depend upon the version. In my install (antix 17.4), /alsa is located within /usr/share.

I have heard that for various reasons muting of alsa output is not uncommon.

One particular cause was a SECOND /ucm2 directory. If that exists, the sound was regained by deleting it.

re: sybok – the alsaucm utility I am not familiar with the use of the program you mentioned earlier to deal with complex sound cards, so I can’t offer any comment about it.

The loss of sound in the archlinux thread involving the creation of a ucm2 directory was associated with an upgrade to alsa-lib and an earlier version (1.1.9.2) solved the problem.

Are the problems reported here associated with an update to alsa-lib? If so, what version?

Hi stevesr0
ucm is in /usr/share/alsa at least on my systems
Finding things like this is easy using synaptic installed files tab. Just look in the directorys.

Thanks. I can confirm that I do not have the ucm2 directory. I only have the ucm directory.

Muting on booting does not appear to be a problem on my system.
But I found this on the Arch forums for those who have this problem.

Output is muted after reboot

Run the following command:

# alsactl restore

If the problem persists, verify that the Auto-Mute option in alsamixer is set to Disabled.
