(I add the same problem with prior kernels, I first tried with 2.6.8). This is a IBM x40 laptop (23865FU) with an intel chipset. The relevant lspci line is: 0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 Audio Controller (rev +01) The driver I use is snd_intel8x0. The problem is that after a suspend/resume cycle the sound output is either off or only on one side or with statics. I tried to do: ~$ alsactl power off ~$ alsactl power on without any change. If I suspend/resume multiple time I can get the sound output a little better (like on one side instead of off). But so far to get the correct sound back I need to reboot. Is it a known problem? Is there a way to force the driver to reinitialized the chipset? Thanks for alsa, Christophe ====================================================================== ---------------------------------------------------------------------- danone - 03-17-06 10:52 ---------------------------------------------------------------------- I have a similar problem on my HP Compaq nx8220. After resuming from s3 sound seems to work with headphones but the inbuild speakers stay mute. Tried several things: rmmod/modprobe soundmodules => doesn't help alsactl power off => wrecks resume playback while suspending => wrecks suspend diff content of /proc/asound before/after => no difference Could it be related to this problem? ---------------------------------------------------------------------- iMil - 05-29-06 11:23 ---------------------------------------------------------------------- same problem here with a nx8220 laptop, kernel 2.6.16, FC5.
