I've recently rebuilt my laptop and now my sound doesn't work. When I add:
to rc.local to set the volume, I get:
aumix: error opening mixer
001:e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
ALSA device list:
#0: Intel ICH6 with STAC9750,51 at 0xdfebfe00, irq 16
When I try to run aumix interactively, nothing happens.
The kernel config is exactly the same as before I rebuilt it, and the sound worked then (I took a copy of the .config file).
Have I forgotten to install something / missed something else?
