Sound configuration on ASUS G752VT

Hello! I am having some issues with setting up the sound properly on a recently purchased ASUS G752. I tried tackling it on my own; I did get somewhere, but there's still a couple of issues. Googling around didn't produce any useful results (it only produced results for G751, but some of the things I tried didn't work).

The laptop has a 2.1 sound system—at least from what I can tell—two speakers on the back of the screen, and a subwoofer, however ALSA reports Front, Surround, Centre and LFE (apart from Master, PCM, Side, S/PIDF, S/PIDF Defa and the Microphone(s), the S/PIDF ones don't allow for volume control, though). It also has 3 ports on the side:


(For people who can't see images), left to right the ports are:

  • "S/PIDF" and Headphones icon

  • Microphone icon (Analog input, I presume)

  • Line Output

So the problems I am having are:

  • Can't seem to get the 2.1 thing to work.

  • Headphone support / jack detection is broken

I managed to get 2.1 working by setting the profile inside pavucontrol to either one of Analog Stereo Output or Analog Stereo Duplex and then messing inside alsamixer with the volumes and hdajackretask with the pin overrides; I don't believe this is the right way to approach the problem, since there *is* a Analog Surround 2.1 profile available in pavucontrol, I just can't seem to get it to work.

Also, I managed to get headphones working through the Line Out and muting the internal speakers, but I don't feel like that's the proper solution. Moreover, there was an audible high pitch when not playing anything that was coming through the headphones (tried multiple ones to eliminate headphones as the problem, and the problem wasn't present on Windows, so I assume it has to do something with the misconfiguration of the output).

However, there's just too many possible combinations to tackle this via my current "bruteforce" method, especially since each method requires a lot of "downtime" while I test the actual sound. Is there a smarter way of approaching the problem?

Furthermore, I am not sure which model to pick, since there is at least eight of them:

  mario			Chromebook mario model fixup
  asus-mode1		ASUS
  asus-mode2		ASUS
  asus-mode3		ASUS
  asus-mode4		ASUS
  asus-mode5		ASUS
  asus-mode6		ASUS
  asus-mode7		ASUS
  asus-mode8		ASUS
  inv-dmic		Inverted internal mic workaround
  dell-headset-multi	Headset jack, which can also be used as mic-in

Interestingly, most (not sure if all) seem to work, but each with its own quirks. I settled on asus-mode5 for now, since that seems to be the one used by G751. I hope I won't have to wait for an  asus-mode9 to be introduced. :P

Re: Sound configuration on ASUS G752VT

I had the same problem.

I haven't tested the microphone or SPDIF capabilities.  But this is a workable pinout for most uses.

#Pin 12 is Internal Mic
0x12 0x90a60160
#Pin 14 is Internal "front" speakers
0x14 0x90170110
#Pin 15 is "Line Out" according to the manual, But Pin 15 won't let me pick that in HDA Jack Retask.
#Trying to use this as an output will have a constant tone too.
#Using this as an output breaks the front speakers working correctly with headphone detection.

#Pin 16 is the headphone jack.

#Pin 18 is the external Microphone jack.

#Pin 19 is nothing.

#Pin 1a is the internal subwoofer.  (Set the sound system to Stereo 2.1)
