It might also be a bug that Phonon, its gstreamer backend or gstreamer itself
shares with PulseAudio. I remember that I had a time where I never had this
issue: AFAIR that was with the Xine backend of Phonon which is now deprecated
and removed from Debian Testing.

alsamixer -c1 sees the following channels:

- PCM front: two volume controls (left/right) - this is the one relevant for me
- PCM back: two volume controls
- PCM middle: one volume control
- PCM bass: one volume control
- PCM sides: two volume controls

without any additional ALSA configuration that is.

I only use stereo. But officially it is a 7.1 surround card, but my receiver
only handles stereo.

And I correct a wrong left volume setting via alsamixer as well, thus it seems
to work in ALSA.
