[jmn]

Package: alsa-ucm-conf
Version: 1.2.4-1
Severity: normal

Dear Maintainer,

After a regular upgrade on Xiaomi Redmibook 14 laptop (Amd Renoir) I found that
the sound stopped working.

Now I have 2 options of the output device:

        1) HDMI1 Output: Family 17h (Models 10h-1fh) HD audio controller
        2) HDMI2 Output: Family 17h (Models 10h-1fh) HD audio controller

None of them works.
The previously working output device was 'Family 17h (Models 10h-1fh) HD audio
controller', same as above but without HDMI prefix.

Using 3.5mm headphones or speakers also didn't show any sound.

The microphone is still working as before.

Here is my lspci -v output:

I found a workaround to make the sound working again, but it makes the
microphone completely disappear from settings.

I just added drivers to a blacklist at /etc/modprobe.d/blacklist.conf:
        blacklist snd_acp3x_rn
        blacklist snd_soc_dmic
        blacklist snd_acp3x_pdm_dma

The last thing to note here, I'm a newbie in linux and may be wrong about the
exact package.

The problem appeared after upgrading these packages:
        alsa-topology-conf:amd64 (1.2.3-1, 1.2.4-1)
        alsa-ucm-conf:amd64 (1.2.3-1, 1.2.4-1)
        gstreamer1.0-pulseaudio:amd64 (1.18.1-1, 1.18.2-1) + other gstreamer1.0
related packages

Thank you
