Need help to decrypt error messages
I have no sound with this sound card
VIA Technologies|VT8233 [AC97 Audio Controller], the module snd-via82xx seems to be loaded correctly. I have found the following error message extracted from dmesg
via82xx: Assuming DXS channels with 48k fixed sample rate.
Please try dxs_support=1 or dxs_support=4 option
and report if it works on your machine.
PCI: No IRQ known for interrupt pin C of device 0000:00:11.5. Please try using pci=biosirq.
unable to grab IRQ 0
VIA 82xx Audio: probe of 0000:00:11.5 failed with error -16
I tried the options dxs_support=1 or = 4 (no effect) but I'd like to understand what mean the last 3 lines.
(Other error message extracted from /var/log/boot.log:
Feb 26 23:15:23 portable_linux alsactl: alsactl: load_state:1134:
Feb 26 23:15:23 portable_linux alsactl: No soundcards found...
Feb 26 23:15:23 portable_linux sound: R?glage des param?tres du mixeur failed)
Thanks for help
