Hmm. I re-enabled hyper-threading (to test) and sound didn't come back.
So I disabled hyper-threading again.
Before I disabled hyper-threading the first time I tried updating my
BIOS, and in order to do that my BIOS reconfigured itself to enable some
networking features so it could update the BIOS over the Internet.
Turned out my BIOS was already at the latest version (details are here [1]).
I'm not sure how to diagnose a "no sound" issue. I've checked all the
volume controls I know about, and nothing is mute and/or low volume.
Sound was working this morning, and now, after I changed my
hyper-threading settings, it's not.
Dunno what happened or why. Totally stumped.
