no audio



Hi All,
I sure have bad luck with maintaining audio on my Linux devices.
But I was going to try to set up my Asus 701 to play  audio from an SDR 
dongle, using SDRtrunk.
So I sent over a tar file to that computer and unpacked it with tar, but I 
hadn't installed it yet.
I did apt update and apt upgrade and all was okay so far.
I rebooted with the dongle in and I heard espeak doing its usual startup 
messages, but I lost audio after that.
I can usually test audio over SSH, and it sends no audio with the usual 
audio tests.
I unplugged the dongle, but still no audio.
I'm thinking that this SDR receiver may be seen as a soundcard, even though 
it is just a receiver.
I rebooted without it plugged in and still only the startup audio, saying 
audio for espeak is enabled and something about cups.
Maybe it has nothing to do with the SDR dongle, and something with the 
update.
It's running Bull'seye 32 bit version.
If anyone has any suggestions on restoring audio, it is much appreciated.
