Comment 2 for bug 1905027

Hello,
thanks for this feedback. My problem is that I cannot identify the real root of this. Which alsa to select ?

alsa-lib and alsa-driver are not installed.

This command gives "*alsa*" installed on my computer.
apt list |grep alsa | grep installé

Output is
alsa-base/focal,focal,now 1.0.25+dfsg-0ubuntu5 all [installé]
alsa-topology-conf/focal,focal,now 1.2.2-1 all [installé, automatique]
alsa-ucm-conf/focal-updates,focal-updates,now 1.2.2-1ubuntu0.4 all [installé, automatique]
alsa-utils/focal-updates,now 1.2.2-1ubuntu2 amd64 [installé]
gstreamer1.0-alsa/focal,now 1.16.2-4 amd64 [installé]
libsox-fmt-alsa/focal,now 14.4.2+git20190427-2 amd64 [installé, automatique]

But I cannot select alsa-base for exemple.
