Do this switch change the output of center and lfe when you run
speaker-test -c 6 -t wav -D hw:0,0
I only hear the font left and font right in both side of my headphone(the one for android)
seem that your are not using latest alsa driver
The alsa driver? Well, shall I try the latest kernel?
Do the channel swap at the orange rack at rear panel ?
Do you have a speaker to test ?
At the front panel, not swap, I heared front left and front right in both side. At the rack panel, swaped. For the normal headphone(speaker) The font left and font right is switch the side.
Fix the device part of four line out from speaker to line out for ECS A780GM-A
No more "Rear Mic Jack Mode" , "Front Jack Mode" and "Line Jack Mode" after this fix when there is no internal speaker
those jack mode switches are redundant when the computer have both Line in jack and Mic jack
Could you give a proper patch that can be merged to upstream? See Documentation/SubmittingPatches.
thanks,
