Hi,
What is the best way to test/debug the alc668 driver these days?
I am running kernel 3.14.1 (debian testing/sid).
The laptop is an ASUS N750JK.
Sound works for front left/right speakers but the back speakers and external lfe channel is not working on this laptop.
- I have found a couple of kernel bug reports for other ASUS models with this chipset but they are both marked resolved. Should I open a new ticket ?

- I can hear static through the front speakers (with pulseaudio test) if I set pins 0x19 and 0x1a to Line Out (Center/LFE) and Internal (Center/LFE) or vice versa with hdajackretask.
Pin 0x16 does not appear to work at all.
I see this output when I apply the config in hdajackretask.
