Over in #lfs-support on IRC, a user has reported that, after updating to alsa-lib-1.2.5, HDMI Audio no longer works on his system. The user linked to this patch:

However, Arch has more patches, including ones for compatibility with Pipewire+Plasma, so we should apply those as well:

alsactl in alsa-utils is also known to segfault, as I just reproduced after I rebooted. Patches here:

This seems pretty serious.

I wonder how long it will take for upstream to release new versions of alsa-{lib,utils}.

comment:3 by Douglas R. Reno, 2 years ago

I'm not sure, Arch and Gentoo both issued patches as recently as 3 days ago after upstream said that they were having problems with their repositories. On most bug reports filed about this (issues such as microphones entirely vanishing), they just point to the commit in "master" and tell people to apply it manually.
