Description Rick 2013-03-13 23:38:41 UTC

Created attachment 95351 [details]
alsa data collected with script file alsa_utils_alsa-info.sh

Alsa doesn't work on this laptop in kernel 3.7 but does work with LTS kernel.

In short:  
- 3.0.67 works
- 3.7 doesn't see outputs without model=6stack
- 3.7 doesn't switch GPIOs with model=6stack
- 3.7 works with model=6stack and GPIO 0 enabled manually

All trouble-shooting details can be found here:  https://bbs.archlinux.org/viewtopic.php?id=158677
(Worked through issue with mich41)


The attachment was collected with alsa_utils_alsa-info.sh

I collected it after a normal boot (using kernel 3.7, not the LTS -- and without mmodifying alsa settings with modprobe or in any other way).

If you need any additional information, please contact me and I'll be happy to gather it for you.

Best,

Rick

You need to figure out which pin actually corresponds which I/O.
BIOS on your machine is utterly broken, and sets all the pin default configuration to 0, thus the driver has no way to know about pins.

It can be done only with the real hardware, so no other can help, unfortunately.
