Four Conductor Headset - Alsa Setting - Asoundrc

posted it in the official boards also

Folks,
I'm struggling with audio settings in Alsa (.asoundrc) to make this headset function properly. Microphone works ok (Sub Mic as Right Input Source), though output sound seems to be missing a channel (sounds like it is inside a pipe, distant sound). When i press on/off button (cuts mic input), sound plays perfect.

edit:

Any ideas? Merge/swap channels? Pulseaudio?

thanks for any help

And as discovered in the other forum, iPhone headphones, proprietary connector not compatible with Pandora.
Cut something open and switch the microphone and ground lines.
