This is the debdiff for groovy. thx.
** Description changed: - This bug is for tracking purpose. + [Impact] + Recently the ucm added some amixer settings, like this one: + cset "name='rt711 ADC 23 Mux' 'MIC2'" + This setting is needed for Dell soundwire audio machines, and only + this setting is set correctly, the headset-mic could work. And we + already backported this ucm to focal. But the alsa-lib ctl parse + doesn't support the enum value in the '' yet, so this amixer setting + can't be set correctly under current focal and groovy, we need to + backport a patch from alsa-lib master branch. + + [Fix] + Backport a patch from upstream, this patch is not in the groovy + yet (not in the alsa-lib v1.2.3.2), so both groovy and focal need this + patch. + + [Test Case] + On the Dell soundwire audio machine, run alsactl init, then check if + the amixer "rt711 ADC 23 Mux" is set to "MIC2" or not, if it is set + correctly, it means the alsalib enum ctl parse support both "" and '' + now. + + + [Regression Risk] + This could introduce failure on setting enum amixer settings, users + will experience the failure of audio device like the speaker can't output + sound, the mic can't record sound. But this possibility is very low since + we have tested this SRU on many LENOVO and Dell machines (with and without + soundwire audio), all worked as fine as before. ** Patch added: "alsa-lib_1.2.3.2-1ubuntu2.debdiff" https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1899857/+attachment/5422368/+files/alsa-lib_1.2.3.2-1ubuntu2.debdiff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899857 Title: [SRU] alsa-lib: support the enum value settings both in "" and in '' To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1899857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
