[alsa-devel] Intel HDA & Realtek issues on ASUS G751JM

[Nicolae Rosia]

Thank you very much!
I have compiled hdajacksensetest from source and found out that one
pin was marked as Not connected even though it was present, and
another one was marked as Microphone.
I have used hdajackretask to force the retask at boot time (it didn't
work at runtime - it always displays tee:
/sys/class/sound/hwC1D0/reconfig: Device or resource busy) and now it
looks like this:
./hdajacksensetest -c 1 -a
Pin 0x12 (Internal Mic): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x15 (Green Line Out, Rear side): present = Yes
Pin 0x16 (Green Line Out, Rear side): present = Yes
Pin 0x18 (Green Line Out, Rear side): present = Yes
Pin 0x19 (Not connected): present = No
Pin 0x1a (Internal Speaker): present = No
Pin 0x1b (Not connected): present = No
Pin 0x1d (Not connected): present = No
Pin 0x1e (Internal SPDIF Out): present = No
Pin 0x1f (Not connected): present = No

After this, I have modified the pulseaudio config,
/etc/pulse/daemon.conf, by adding the following:
default-sample-channels = 6
enable-lfe-remixing = yes
and 5.1 works!

How can we fix this for other owners?
