complete output of pulseaudio -k; pulseaudio -vvvvv

I'm trying to get a Behringer FCA610 (connected via USB) to work with
PulseAudio on Fedora 20 Heisenbug running with kernel 3.14 (and also
Ubuntu 14.04 with Kernel 3.14). As far as I understand the device works
fine with ALSA, but PulseAudio fails to configure the device properly.

The device itself seems to be detected fine according to dmesg:

I really like to get this device working pulseautio. Any assistance is
very much appreciated.

6 channels capture can be added similar to 4 channels capture

Thanks for the verbose log. Unfortunately, it still does not contain all
the information that is needed to debug this. Your message indicates
that aplay can produce sound. Could you please paste the output of the
following command?

aplay -vv -D plughw:CARD=FCA610,DEV=0 Musik/test-6ch.wav

If that fails:

aplay -vv -D plughw:CARD=FCA610,DEV=0 -c 10 Musik/test-6ch.wav

Also, there was a very similar discussion in January this year. Please
read it, maybe it contains some ideas applicable to your case:

Wow, thank you very much Alexander. I followed David's suggestion for a
workaround (http://lists.freedesktop.org/archives/pulseaudio-
discuss/2014-January/019748.html) to create the multichannel.conf
profile and added the following to
/lib/udev/rules.d/90-pulseaudio.rules:

# Behringer FCA610
ATTRS{idVendor}=="1397", ATTRS{idProduct}=="0003", 
ENV{PULSE_PROFILE_SET}="multichannel.conf"

I can use the device for the first time! :) I haven't read the entire
thread yet, but it's very late and I need to get some sleep. Getting
6ch/5.1 playback functionality (and probably stereo input) is what I
wanted from PulseAudio. (If really want to make use of all channels I'd
look into JACK.) I will come back once I looked deeper into this.

you need jackd for stereo capture since pulseaudio downmix 6 channels

Pulseaudio 6.0 -vvvvv output on Ubuntu 15.04

Sorry for replying so late. I noticed that 6.0 was uploaded to Ubuntu
15.04 recently. On my clean testing system 6 inputs are now available in
sound settings and pavucontrol, but outputs are still not discovered.

I think I see what the bug is in the latest log - the "multichannel"
mapping seems to be shared between input and output mappings:

 1) Detect that output supports only 10 channels
 2) Change mapping "multichannel" to 10 channels
 3) Detect that input supports only 6 channels
 4) Change mapping "multichannel" to 6 channels
 5) Try to open output on mapping "multichannel" with 6 channels, and fail.

The second of the three is a patch as suggested by Raymond and should
fix this issue, but the third makes sense to test in combination with
the second.

If you have time, please test and let me know if it fixes the issue.
Thanks!
