[Gerasimos Melissaratos]

Package: alsa-ucm-conf
Version: 1.2.2-1
Severity: important
Tags: patch

Dear Maintainer,

After updating kernel to linux-image-5.5.0-1-amd64, pulseaudio reports:

pulseaudio[115411]: E: [pulseaudio] module-alsa-card.c: Failed to find a
working profile.
pulseaudio[115411]: E: [pulseaudio] module.c: Failed to load module "module-
alsa-card" (argument: "device_id="0" name="pci-0000_00_1f.3-platform-
skl_hda_dsp_generic" card_name="alsa_card.pci-0000_00_1f.3-platform-
skl_hda_dsp_generic" namereg_fail=false tsched=yes fixed_latency_range=no
ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no
card_properties="module-udev-detect.discovered=1""): initialization failed.

and the sound card is not working

The following diff seems to resolve the problem:
