Simple mixer control 'Swap Center/LFE',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off]
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 ?
I am very sorry, I mistake the meanings of the mircophone and speaker. What I used is the headphone. For the android headphone 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.
This switch seem lost in the latest alsa driver
Thank you
