Request for testers to test the patch
Multistreaming allows you to listen to one audio source through the back panel speakers and a second audio source through front panel headphones
or
speakers.
Hardware requirement
- 10 channels realtek codec (e.g. alc892) which already work with
model=auto 2) Headphone at front panel and Line out at rear panel
"hw:0,0" is used for the rear panel audio jack "hw:0,2" is used for the front panel headphone when "Independent HP" is switched ON
Add an "Independent HP" switch to turn this feature on/off for desktop
for
those HDA codec
Test:
- speaker-test -c 8 -t wav -Dhw:0,0
- speaker-test -c 2 -t wav -Dhw:0,2
It will need modification to support this feature for those desktop with
8
channels codec
So i made the test, i correctly hear the tests, 7 outputs for the rear panel, and 2 for the front, but when i play the first test, i hear on the front panel some noise and realy crackly and whispered the tests when front left and front right are played, i guess it is not normal, may this help?
using hda-emu , it seem that the "Headpone Playback Switch" still using 0x0c instead of 0x26
