After some googling around without any results, I'm quite puzzled. Since some past update I can't precise, kernel 2.6.164 works fine, however 2.6.194 has some sound problem in my somewhat old and beaten Toshiba laptop.
-Audacious plays OK but other applications have problems.
-For instance, mplayer acts quirky: when I pause a playing video, sound keeps stuttering endlessly. The same happens sometimes when I close mplayer window.
-system-config-soundcard detects the card and starts to play sample but stuttering all the way, repeating every 4th of a second or so some 16 times, at about a 1/2 second rate.
-Youtube has no sound!
-Software volume control has been lost long ago, unrelated to this problem but interested in recovery anyway
System is fully up to date. Any hints will be appreciated!
Some relevant lines in my /etc/modprobe.conf as is now, with some scars left after unfruitful battles:
alias snd-card-0 snd-hda-intel
#options snd-card-0 index=0
#options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel
options snd-hda-intel model=auto
options snd-hda-intel probe_mask=1
options snd cards_limit=8
