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.
You have to post output of alsa-info.sh
Seem BIOS only set up the front speakers
How many audio jacks ?
Standard headphone/mic + yellow external lfe (sonic master). There is also hdmi but I am not testing that at the moment.

Do you mean headset ?
Do it support headset or headphone ?
Do you mean there are four internal speakers ?
There are two front speakers which produce sound through the front bottom of the case. There are also two back speakers which do not produce sound in my tests so far.
Do it support surround40 in windows ?
I am not running windows OS on this machine but I suspect it does.
The external sonic master and headphone need two volume controls but alc668 only have three
The best way to test is using latest git version and hda jack retask to
The process has changed somewhat since I last did this.
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/log/sound/pci/h...
- four internal speaker and headphone
- two internal speaker, headphone and external subwoofer
Once you confirm the nodes of the speakers, subwooder You need to decide whether headphone share the volume controls with the speaker/subwoofer
I have spent some time on this step already with 3.14.1
Did you retask the node of subwoofer as speaker or line out ?
For multi channel, the sequence number is ascending and the driver expect they have same type i.e, all speakers or all line out jacks
Did you find the node of the rear speakers in (1) ?
Did surround 4.0 work when you fix the rear speaker ?
Did you find the node of the external subwoofer in (2) ?
Did the sonic master subwoofer detected ? hda jack sense test -a
Do the subwoofer only use right channel ?
Do surround 2.1 works ?
Is there a specific reason this process is not already scripted other than no one has taken the time to do it?
Do surround 4.1 or 5.1 work when you fix both speaker and subwoofer ?
Do you prefer driver create headphone volume control or subwoofer volume control ?
Can we not create a test script that will run through all the logical combinations and provide all the relevant info?
The driver hardcore the name of volume control to bass when there are two speaker nodes for those 2.1
- 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.
