How does PlaybackChannelPos# Work?

[13r0ck]

I found https://github.com/alsa-project/alsa-lib/commit/0ba999591b78e07a4b8e610ebced2c388197e36e but doesn't seem to work when setting audio jack output.

I have a mostly working configuration for a motherboard's 3.5mm audio jack output. The only problem is that the C/Sub and Rear jacks are flipped. I am assuming setting the PlaybackChannelPos in the speaker should work, but it doesn't for some reason.

SectionDevice."Speaker" {
    Commant "Speakers"
    Value {
        PlaybackChannel2 "BL"
        PlaybackChannel3 "BR"
        PlaybackChannel4 "FC"
        PlaybackChannel5 "LFE"
    }
}

Any help would be greatly appreciated!

This feature is not supported in the sound servers at the moment. We just define the way to describe the devices, but the applications using UCM should use those values and implement the functionality.

Thank you for the uodate, is there another way to swap the output terminal for the BR/FC channels?
