A recent update to the ALSA package (1.2.6) in Alpine Edge has broken audio profile switching when phone calls are placed.
A proper fix is still being investigated. In the meantime,
have been forked to pmaports and downgraded to 1.2.5. They show up as version
9999-r0 when upgrading:
(1/6) Upgrading alsa-lib (1.2.5-r2 -> 9999-r0) (2/5) Upgrading alsa-plugins-pulse (1.2.5-r2 -> 9999-r0) (3/5) Upgrading alsa-ucm-conf (126.96.36.199-r1 -> 9999-r0) (4/5) Upgrading alsa-utils (1.2.5-r2 -> 9999-r0) (5/5) Upgrading alsa-utils-openrc (1.2.5-r2 -> 9999-r0)
Once a proper fix for the ALSA ucm config has been identified, the packages will be removed and replaced with versions from Alpine's aports.
