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.
