Hello Group -
I'm really confused about what's gone wrong with my sound. Total
Silence even though it was working less than two weeks ago after an
upgrade to 8.10. User error?, or a bad patch maybe...can you help?
I'm running ubuntu 8.10 on a 64-bit machine

I have done some research and have been following the steps I found at

First step is this:
results appear normal.
reid@linux-rv:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: V8237 [VIA 8237], device 0: VIA 8237 [VIA 8237]
Subdevices: 4/4
Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
Subdevice #2: subdevice #2
Subdevice #3: subdevice #3
card 0: V8237 [VIA 8237], device 1: VIA 8237 [VIA 8237]
Subdevices: 1/1
Subdevice #0: subdevice #0
reid@linux-rv:~$

Second step:
reid@linux-rv:~$ lspci -v
00:11.5 Multimedia audio controller: VIA Technologies, Inc.
VT8233/A/8235/8237 AC97 Audio Controller (rev 60)
Subsystem: ASUSTeK Computer Inc. Device 80b0
Flags: medium devsel, IRQ 22
I/O ports at c800 [size=256]
Capabilities: <access denied>
Kernel driver in use: VIA 82xx Audio
Kernel modules: snd-via82xx
Looks Ok, I think
______________________________________________________________________
Third step:
reid@linux-rv:~$ sudo modprobe snd-via-82xx
[sudo] password for reid:
FATAL: Module snd_via_82xx not found.
reid@linux-rv:~$
That's not good, or expected.
Fourth step (sorry about the screwy formatting):
reid@linux-rv:~$ lsmod|grep snd
snd_via82xx 36904 3
snd_via82xx_modem 21900 0
gameport 21776 1 snd_via82xx
snd_seq_dummy 11524 0

snd_page_alloc 17680 3 snd_via82xx,snd_via82xx_modem,snd_pcm
soundcore 16800 1 snd
So...I'm not sure what to look for here....
Any thoughts would be appreciated.

Hi Reid.
The first thing I'd check out is alsamixer, as all the modules appear to be
loaded. There is a typo on your 3rd step. Module should be snd-via82xx, not
snd-via-82xx. That aside, open alsamixer as user, as below, and check for
sliders that may be down at zero, or may be muted since the updates. Typical
controls are, Master, PCM, Front, CD. "M" key toggles the mute/unmute.
alsamixer -D hw:0
All the best.
Nigel.
