Replying to [comment:4 aelschuring]:
> I would, but there is no surround71 device for this card and not a
single device that maps to hw:0,2. What would be the difference between
front0 and accessing hw:0 with 2 channels?
Then that's the problem here. If front:xxx does not work then please make
sure that this gets fixed by ALSA. The autoconfiguraton n PA relies on
front:xxx, surround51:xxx and friends to be available.
> > Could you please retry with 0.9.16-test4? Some drivers seem to have
issues with the order in which buffer/frag size is configured. This is
turned around in test4.
> Yep, seems fixed: it also adds more profiles (digital surround IEC), but
still only spdif profiles. module-alsa-sink also appears to work, but it
configures 10/12 out/in channels even though the load-module line says
channels=8. Using device front:0 (without a channel map) gives me the same
10/12 channel options.
Your front:xxx device is broken. It's supposed to support only 2ch. A
front:xxx device that only knows 10/12 channels makes no sense. Please
make sure to get this fixed in ALSA.
If you ask for 8 channels but the underlying alsa drver refuses to do that
PA will pick the next channel setting that is supported, if you use
module-alsa-sink directly.

independant inputs 0.9.16 now introduces the ability to define the set of
exposed profiles via config files. Please read up on this here:

> Quite some text. I'll see what I can find and let you know. One question
immediately comes up: where should I put this configuration? In a new file
in /etc/pulse, in ~/.pulse? Do I need to load-module it manually, or will
it be auto-detected based on extension or filename?
You need to place them in the same dir as the audio4dj files and make sure
to add a rule to /lib/udev/rules.d/90-pulseaudio.rules so that the profile
set is properly detected for your devce. You need to be careful there
however, since quite a few devices are based on the ice1712 chip, so you
must make sure that your file only matches against the Terratec model.
