I just bought a laptop and installed debian next to Windows on aT dual boot. The only way I can get sound to work is with an .asoundrc file through my USB headset. It works perfectly that way, but I need sound through the system speakers.
Here is some information about my system:
e$ cat /proc/asound/cards
0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfeb44000 irq 19
1 [Headset ]: USB-Audio - Logitech USB Headset
USB Headset at usb-0000:00:12.0-5, full speed
2 [Generic_1 ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfeb40000 irq 16
$ cat /proc/asound/devices
2: : timer
3: : sequencer
4: [ 1- 0]: digital audio playback
5: [ 1- 0]: digital audio capture

$ cat /proc/asound/modules
$ lspci | grep Audio
00:01.1 Audio device: ATI Technologies Inc Device 1714

# this makes sound work with my headset. i've tried choosing different defaults without the headset, but nothing seems to work
$ cat .asoundrc
When I run alsamixer, if I choose card 2, HD-Audio Generic (card 0 is also named HD-Audio Generic), I can see the usual 6-10 channels for the different devices and adjust them like usual, but if I choose the same card in gnome-volume-control, I can't see any channels at all, there is just a check in a box for IEC598. Gnome does not seem to recognize something I need it to recognize.
I know that the laptop tspeakers work, because they work in the Windows half of the dual boot. I can't use the FN button to adjust
volume in Linux though, like I do in Windows. Pressing the FN + F8 key (volume up on my computer) in Linux brings up the little volume splash screen, but further presses do not adjust the volume in any way. I don't think this is the problem though. It seems that gnome doesn't recognize the sound card I want it to.
I have RTFM, at least a good part of it, but I'm a little confused as to how to proceed. A lot of things that have worked for other users I can't get to work for me. Any help you could offer would be much appreciated.
