I do that so seldom, I had forgotten I could. Its been years, literally.

And just how do I accomplish that when no one is logged in? I've
tried /path/to/aplay /path/to/file in /etc/rc.local and its as if
its ignored. There are other things in rc.local that do get done.
Not there now as I took it out when it didn't work. If aplay doesn't work in rc.local and other things
do work in
rc.local, what makes you think that ALSA works before logging in to
TDE?
I can hear the background noise of the sound system when it has no input.
That comes on when the boot log is only about half done with a pretty
obvious thump in the speakers. So I have to assume the sound is usable
at that point, but goes away as x starts.
Don't forget that I have 50 some years in as a broadcast engineer, and I
notice such things and connect the dots a lot easier than most. My ears
at my age aren't great, carhart notches at 4 khz are 140 db deep, but
voice frequencies are good yet. As are crickets amazingly. I wore out a
couple 30-06 barrels before they started selling decent earmuffs in the
1960's. That will give anybody carhart notches.
The speaker-test will tell us whether ALSA is working
before TDM
login.
I'll do that next time I reboot. My system is simple stereo, left and
right only, but I expect the man page will tell me how to test both
sides. Thanks for the reminder.

Sound of any kind. Even the beep of incoming email is silent until I do
the alsactl restore thing.
