I finally got it work using this alsa configuration:
Because MythTV setup woun't let you set these new output device and
mixer control, you'll have to set them directly in the database by hand:
update `mythconverg`.`settings` set data='ALSA:softvol' where
update `mythconverg`.`settings` set data='SoftVol' where
All other audio settings are the same as described in my initial mail.
Now my remote makes use of the new SoftVol mixer control which is
responsible for all six channels.
