Have you tried?
Code: Select all
modprobe -r snd_intel8x0
modprobe snd_hda_intel
It will tell you what each pin on the chip is supposed to do. Sometimes the BIOS can tell the chip to use the wrong pin. If you can identify a pin with sound, work out its ID (in hex) and see what hdajackretask says that pin is doing, You can retask the pin. For some people it seems to work. If it doesn't, you can reboot to reset. If it works, apply the boot override. It's part of alsa-tools I think.
