Hello,

I don't know to what degree, if at all, the following is related to your 
issue. It looks to me as if your audio hardware is Intel related. For 
some time now that speaker-test, from alsa-utils, is not working for me. 
I think the whole sound system does not work. speaker-test is just a 
sympthom. Some more details are: 

Kernel driver in use: snd_hda_intel

    linux 5.15.2.arch1-1
        (I have newer kernel. it is just when I wrote down 
         the alsa packages version)
    alsa-lib 1.2.5.1-3
    alsa-topology-conf 1.2.5.1-1
    alsa-ucm-conf 1.2.5.1-1
    alsa-utils 1.2.5.1-1
    zita-alsa-pcmi 0.3.2-3

There is no problem with a live CD, which is an arch deraivative. It has 
the following:
    linux 5.12.13.arch1-1
    alsa-firmware 1.2.4-2
    alsa-lib 1.2.5.1-3
    alsa-oss 1.1.8-3
    alsa-topology-conf 1.2.5.1-1
    alsa-ucm-conf 1.2.5.1-1
    alsa-utils 1.2.5.1-1
    zita-alsa-pcmi 0.3.2-3

There fore, I think something between June 2021 and now broke the sound 
system.
I am trying to bisect it, but have no results so far.
