Hello, for quite some time the "Smart 5.1" function in alsa is not working  
properly when motherboard has only 3 audio jacks.

Me and Raymond on alsa-bugtracker have been trying to solve the issue for  
a long time but were unsuccessful.

Please take a look at this alsa bug ticket:  
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4895

It contains A LOT of info on the problem + steps that we tried, which  
included patching the code.

Synthom : NO "Surround" , "Center" and "LFE" Control and switch with  
VT1708S on a motherboard with 3 audio jacks
Also NO surround sound.

speaker-test -c 4 -t wav -Dsurround40

Channels count (4) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument

Please advise if you can.

Thank you
Best Regards
Viliam Kubis

>> It might be. It is important not to mix VT1708 and VT1708S. For VT1708S,
the following DACs are used in code:

  /* config dac list */
  switch (i) {
  case AUTO_SEQ_FRONT:
  	spec->multiout.dac_nids[i] = 0x10;
  	break;
  case AUTO_SEQ_CENLFE:
  	spec->multiout.dac_nids[i] = 0x24;
  	break;
  case AUTO_SEQ_SURROUND:
  	spec->multiout.dac_nids[i] = 0x11;
  	break;
  case AUTO_SEQ_SIDE:
  	spec->multiout.dac_nids[i] = 0x25;
  	break;
  }

>>  So 0x12 is not used for any of the surround outputs.

I think your testing config is not compiled with smart 5.1 requirement

Refer to smart51_get() , this function exepct red jack and blue jack
are configued to Output

But you still plugged in Mic into the pink jack according to your photo.

Your speakers have to plugged in both pink and blue jacks
