Question VT8233/A/8235/8237 audio problems on fedora 6


is anyone can help? I have a problem with sound on my pc. It did work at first, but when after I rebooted it doesnt. system-config-soundcard still shows that detected soundcard is VT8233/A/8235/8237 AC 97. However, when I try sound test, I hear nothing. Also, no PCM devices are present in this dialog box. I use fedora core 6. The output of lspci:

[root@winlin ~]# lspci

Unhappy It's not just Fedora

I'm running OpenSuse 10.2 and I also have what appears to be the same problem. In my case the sound card installer (a part of YaST) gave me the message:

Quote:
The kernel module snd-via-82xx for sound support could not be loaded. This can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
Sound was working for me until recently, so I suspect that some slightly botched kernel update is the villain here. I will admit that I have not tracked all the revisions to my system introduced by online updates, so I can't tell what change induced the error.

The net effect is that sound doesn't work at all.

I dont have this issue anymore... I mean I do but I have a solution. If you can call that solution
I found out that sound sometimes would work after reboot. sometimes it wouldnt. Whenever I reboot and I have sound, I dont turn off my PC anymore So thats my solution. I dont know if you have the same thing but try rebooting your PC.
By the way, another interesting thing. I had kind of the same issue with my printer. Sometimes it wouldnt work, sometimes it would. If it would work after reboot, I wouldnt turn of my PC Another great solution. That's what I would get from dmesg if it wouldnt work:

usb 1-2: new full speed USB device using uhci_hcd and address 5
usb 1-2: new full speed USB device using uhci_hcd and address 6
usb 1-2: configuration #1 chosen from 1 choice
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 6 if 1 alt 0 proto 2 vid 0x03F0 pid 0x4D11
usb 1-2: USB disconnect, address 6
drivers/usb/class/usblp.c: usblp0: removed

It seems that rebooting is a cure for all diseases...

I just updated ALSA from version 1.0.10 to version 1.0.13 and -- miracle of miracles -- my sound is working again.
