Listmates,
I have the most atavistic sound known to mankind on my laptop running arch.
Sometimes it works, sometimes it doesn't. The card specs are:

When I first start arch and start kde, everything is fine. However, if I log
out and then back it, most times the sound is gone -- dead. The sound will
not start again until I reboot. Anybody got any ideas on what to check or
what to keep a watch out for? Also, any ideas on how to bring the sound back
once it dies without having to reboot?
Thanks for any help you can provide. I always hated chasing sound problems.
snd-hda-intel encompasses many different chipsets/codecs. Which one
does your card use? You can find out like so:
[darose@daroselin ~]$ grep Codec /proc/asound/card0/codec#0
Codec: IDT 92HD71B7X
As far as general things to check/try:
* Try restarting the KDE sound system.
* Try checking to see if anything got muted in the mixer (i.e., check in
Kmix or alsamixer).
* Try seeing if this is a KDE issue or not by hitting ctrl-alt-F1,
logging into a non-X console, and testing the sound using alsaplayer.
* I had a problem with my sound card whereby "analog loopback" was
getting set and muting the sound. (See:
http://bbs.archlinux.org/viewtopic.php?pid=535521#p535521) Tore my hair
out over that one for a LONG time. Maybe this is your issue too?
HTH,
DR
