Discovered due to https://github.com/thesofproject/sof/issues/3519 The microphone array on this laptop does not work out of the box (i.e., with pulseaudio) without one or both (unsure) of media-libs/alsa-topology-conf and media-libs/alsa-ucm-conf. Currently *nothing* in gentoo.git depends on either of these packages, so you have to know that they're needed for your hardware. These two packages are ~300kB each, and the failure mode without them is not easily debuggable. Just search for this laptop's model number (x360 13-aw0xxx) and "microphone" to see all of the problems! Should alsa-lib just depend on these packages to avoid this problem? Or should pulseaudio?
Cc'ing Polynomial-C since he added these packages and might have an opinion.
To be honest, I only added the alsa-*-conf packages because I saw in upstream's changelog that they had been split off of alsa-lib package. IMHO your inquiry makes sense and we should make alsa-lib depend on these packages.
Thanks! That's great information.
Indeed, we might as well put an explicit dependency without a USE-flag to start with. If an appropriate USE-flag comes to light we can revisit. Non-debuggable breakage is bad.
