After the alsa-lib 1.2.14-2 → 1.2.15-1 upgrade, all of my software stopped outputting any sound.

I noticed it because I have a mpd server playing music on that computer, and music stopped right after the upgrade.
When I tried mpv instead, it showed an explicit error about ALSA:

$ mpv http://radio.vv221.fr/
● Audio  --aid=1  (opus 2ch 48000 Hz)
ALSA lib pcm.c:2722:(snd_pcm_open_noupdate) [error.pcm] Unknown PCM cards.pcm.default
[ao/alsa] Playback open error: No such file or directory
[ao] Failed to initialize audio driver 'alsa'
Could not open/initialize audio device -> no sound.
Audio: no audio
Exiting... (Errors when loading file)

Reverting to alsa-lib 1.2.14-2, everything goes back to normal.
On my system, it means installing the 1.2.14-2 version of:
- - libasound2-data
- - libasound2t64
- - libatopology2t64

I run an ALSA-only setup, without PipeWire, without PulseAudio.

I have not tried rebooting the system after the alsa-lib upgrade (this computer is dual-classed as a server, reboots are inconvenient).
