ras pi 4b no ALSA sound cards

I haven't worked with a Pi4 but a few of us were throwing stuff into this post concerning audio. 

/products/raspberry-pi/b/blog/posts/alsa-no-audio-glitch-issue-pi-4-fix

It was centered around Raspberry Pi OS, not sure if it helps.

Thanks, colporteur. I read that post pretty carefully, I think, but did not notice any clear suggestions other than the removal of pulseaudio, which did not do the trick for me. If I missed something else that's worth trying please advise and I will definitely do it. There were unfortunately no reports there that mentioned VoidLinux and that may have some bearing on my problem, but it does seem hard to imagine that ALSA and/or other kernel drivers should have any VoidLinux-specific issues.

Thanks again!

Sorry if I provided false hope. My experience is limited to Raspberry Pi OS and a few Linux distros. I look at the posting link I sent you, like a collection of threads I pull on when I have audio issues. I have gotten some success in the past but maybe that is long past.

I have never managed to get my head around the ASLA and Pulse audio framework. Throw Jack into the mix and yeah it is a mixer.

No worries, I greatly appreciate your effort to help me and many other folks solve this problem!

I was able to fix my problem after further web searches. My original installed /boot/config.txt contained the line

#dtparam=audio=on

Note that the line was commented out, thus apparently disabling audio. I had to uncomment it, and then the ALSA service installed from the VoidLinux alsa-utils package was able to detect both my HDMI and analog jack output devices.

Curiously, /var/log/dmesg.log displays a kernel command line near the top of the file which includes the rather suspicious-looking option

snd_bcm2835.enable_compat_alsa=0

I did not make any attempt to change that, but perhaps dtparam=audio=on effectively overrides that?

Hope others find this info useful, although perhaps it is specific only to VoidLinux.

If you don't mind, I am going to put this detail in the ALSA post for future reference?

PS: Just for grins I put back all of the pulseaudio packages I had removed earlier and then started the pulseaudio service.i.e., I now have both of the commands pulseaudio --system and alsa started at boot time. The only I app I really need to run is mpg123 -a outdev mp3file and that continues to work as before. I have no need for pulseaudio so I did not attempt to run any pulseaudio-specific commands.

Definitely not, please do!

I'm beginning to suspect (see my PS post re: pulseudio below) that the problems and solutions for the bulk of the posters in your ALSA reference may be specific to Raspbian, while mine are specific to VoidLinux? Still, the additional info my be of use to someone.
