[Solved] No microphone USB audio Behringer UMC204HD alsa update

No input on my Behringer UMC204HD because of an update in the following packages alsa-card-profiles,alsa-lib,alsa-ucm-conf,alsa-utils,lib32-alsa-lib

alsa-card-profiles 1:1.2.6-1 -> 1:1.2.7-1
alsa-lib 1.2.12-1 -> 1.2.13-1
alsa-ucm-conf 1.2.12-1 -> 1.2.13-2
alsa-utils 1.2.12-1 -> 1.2.13-2
lib32-alsa-lib 1.2.12-1 -> 1.2.13-1

The error messages related by pipewire :

pw.node: (alsa_output.pci-0000_00_1f.3.stereo-fallback-57) graph xrun not-triggered (0 suppressed)
pw.node: (alsa_output.pci-0000_00_1f.3.stereo-fallback-57) xrun state:0x7ba2cfaed008 pending:6/6 s:0 a:0 f:0 waiting:0 process:0 status:triggered

If I revert package the package to these version it works again :

alsa-card-profiles-1:1.2.6-1-x86_64.pkg.tar.zst alsa-lib-1.2.12-1-x86_64.pkg.tar.zst lib32-alsa-lib-1.2.12-1-x86_64.pkg.tar.zst alsa-utils-1.2.12-1-x86_64.pkg.tar.zst alsa-ucm-conf-1.2.12-1-any.pkg.tar.zst

In the meantime I add
--ignore alsa-card-profiles,alsa-lib,alsa-ucm-conf,alsa-utils,lib32-alsa-lib
to my pacman update.

As it seems related to ALSA I also reported the issue on their github :
https://github.com/alsa-project/alsa-uc … issues/479

**EDIT**
only the alsa-ucm-conf package is faulty somewhere between these two version
alsa-ucm-conf 1.2.12-1 -> 1.2.13-2

Workaround downgrade to alsa-ucm-conf-1.2.12-1

Re: [Solved] No microphone USB audio Behringer UMC204HD alsa update

What if you upgrade all packages to the latest version but downgrade only alsa-ucm-conf to 1.2.12-1?
It has a commit (https://github.com/alsa-project/alsa-uc … 02e2.patch) backported that could cause this kind of issue

Re: [Solved] No microphone USB audio Behringer UMC204HD alsa update

You are right the issue is due to alsa-ucm-conf 1.2.12-1 -> 1.2.13-2  only.

Alright, thanks for testing! I will comment on the upstream ticket and make them aware of this breakage.

Re: [Solved] No microphone USB audio Behringer UMC204HD alsa update

Could you please test the following alsa-ucm package that was built from their master?
I just want to make sure that your issue is not caused by a partial backport or something.

sudo pacman -U https://pkgbuild.com/\~gromit/alsa-ucm-conf-v1.2.13.r6.g62acef2-1-any.pkg.tar.zst

Re: [Solved] No microphone USB audio Behringer UMC204HD alsa update

With this package https://pkgbuild.com/\~gromit/alsa-ucm- … kg.tar.zst 
the microphone is working but in the logs I have the error message from above :

pipewire[2522]: pw.node: (alsa_output.pci-0000_00_1f.3.stereo-fallback-56) graph xrun not-triggered (0 suppressed)

although it seems to work.

Re: [Solved] No microphone USB audio Behringer UMC204HD alsa update

Hey sorry for the reports but it ends up that after a full purge and reinstall of all my package related to the sound :

    alsa pipewire wireplumber easyeffects qpwgraph

with the alsa-ucm-conf in its latest version 1.2.13-2 the inputs of the Behringer UMC204HD are working correctly.

The errors I can still see in the logs seems related to wireplumber

    systemd[1]: Manage Sound Card State (restore and store) was skipped because of an unmet condition check (ConditionPathExists=/etc/alsa/state-daemon.conf).
    ...
    wireplumber[1686]: spa.alsa: Unable to load mixer: No such file or directory
    wireplumber[1686]: spa.alsa: Failed to find a working mixer device (_ucm0003.default:U192k).

and some other error seems to be related to easy effects

    pipewire[2590]: pw.node: (alsa_input.usb-BEHRINGER_UMC204HD_192k-00.HiFi__Mic1__source-43) graph xrun not-triggered (0 suppressed)
    pipewire[2590]: pw.node: (alsa_input.usb-BEHRINGER_UMC204HD_192k-00.HiFi__Mic1__source-43) xrun state:0x7ac9670ec008 pending:15/19 s:0 a:0 f:0 waiting:0 process:0 status:triggered

but I can use my microphone correctly through the sound card.

Sorry for mistakenly though that alsa UCM was faulty.
