[alsa-devel] Smart 5.1 function not working on VIA VT1708S with *three* jacks on mainboard

[Viliam Kubis]

Oh my god!! It actually works!!! :) At first speaker-test was not working,  
but with

[kbs1 at localhost a]$ speaker-test -c4 -twav -Dsurround40 <--------- THIS

speaker-test 1.0.23

Playback device is surround40
Stream parameters are 48000Hz, S16_LE, 4 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 32 to 8192
Period size range from 16 to 4096
Using max buffer size 8192
Periods = 4
was set period_size = 2048
was set buffer_size = 8192
  0 - Front Left
  1 - Front Right
  3 - Rear Right <-------------- THIS PLAYS
  2 - Rear Left <-------------- AND THIS PLAYS!!
Time per period = 5.718945
  0 - Front Left
^C
[kbs1 at localhost a]$

Finally! My audio experience is now at a whole new level. Thank you very  
much, I will post this patch to alsa-bugtracker and close the bug, I was  
starting to think that this is a kernel problem, but now it just works  
GREAT.

Maybe you can add this patch to official alsa-driver version on next  
release.

Have a nice day!
Best Regards
