Went ahead and upgraded to 12.04 from 11.10 finally, and lost my sound. Not sure what's going on. If I look at the sound settings in Ubuntu, no devices are listed, however, aplay -l gives me:
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: VT1705 Analog [VT1705 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
Even stranger (to me), if I do an: aplay -D hw:1,3 /usr/share/sounds/alsa/Front_Center.wav, I get this:
Code:
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1087: Channels count non available
I check alsamixer, and I see that the Intel PCH card shows up. Switch to the Nvidia Card, and I just get two devices set to [00] and no ability to change them. So something's screwy.
I also suspected that Ubuntu is using pulse instead of alsa, so I checked pulseaudo -vv from the command line, and the interesting lines appear to be:
Code:
D: [pulseaudio] module-device-restore.c: Database contains invalid data for key: sink:alsa_output.hw_1_3:null
I: [pulseaudio] module.c: Loaded "module-alsa-sink" (index: #4; argument: "device=hw:1,3").
D: [pulseaudio] alsa-util.c: Trying hw:1,3 with SND_PCM_NO_AUTO_FORMAT ...
I: [pulseaudio] (alsa-lib)pcm_hw.c: open '/dev/snd/pcmC1D3c' failed (-2)
I: [pulseaudio] alsa-util.c: Error opening PCM device hw:1,3: No such file or directory
E: [pulseaudio] module.c: Failed to load module "module-alsa-source" (argument: "device=hw:1,3"): initialization failed.
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.
Now, the only thing I can add is that during the upgrade, Ubuntu asked if I wanted to keep an alsa file (I believe ... I skipped through it too fast, but it could have been a pulse file it asked), and I said to keep, rather than replace it. That may have been a mistake. So it could easily be something in either my alsa configuration or my pulse configuration, but I've no idea what or where (and they both seemed too large to just post here randomly unless someone thinks they may be the culprit).
Any help figuring out where to look would be greatly appreciated. I figure I could probably roll back to 11.10 in the worst case, but who knows.
