Done. Rebooted.

Yes, the _very_ first thing I did was ensure the sound was on in
alsamixer.
Tried to play an .mp3 file with mpg123:
[oss.c:172] error: Can't open default sound device!
[audio.c:630] error: failed to open audio device
[audio.c:180] error: Unable to find a working output module in this list:
alsa,oss
[audio.c:532] error: Failed to open audio output module
[mpg123.c:897] error: Failed to initialize output, goodbye.
aplay -l also tells me there's no sound card found. Sigh.
I had a much earlier Sony Vaio model for years (2004-2010) that did not
exhibit these issues. What is my next step?
Many thanks,
Rich
