Hi, A new laptop and as usual I need your help. I cannot see the controls for the 7.1 channels supported by the laptop. I tried to compile a new alsa snapshot just in case it's fixed but I lost the audio device altogether after rebooting. I also tried https://launchpad.net/~ubuntu-audio-dev/+archive/ppa which should be the proper way to update alsa in ubuntu but again the audio device disappears altogether.

I tried to use options snd-hda-intel model=targa-8ch-dig and though I can see alsa controls now for the surround system but only 1 jack is working and the sound is coming from the wrong jack (rear instead of front/headphone) beside other problems.

Attached is alsa-info
