The channel mapping is defined by bChRelationship, not bChPurpose.

The change looks OK, but your sign-off is missing.
If you submit a patch, please give always your signed-off-by tag, no
matter whether it's your original patch or not.

Also, the Fixes tag would be helpful for such a correction.


thanks,

Takashi

Somehow I overlooked this, so in my case of Generic Audio it is always
mono.
