[pulseaudio-discuss] Behringer FCA610 (USB) cannot be picked up and configured by PulseAudio

[Benjamin Tegge]

Hello everyone,

Somehow my message from earlier either didn't make it to this list (too
large attachment) or didn't receive any replies. I just filed a bug at
the bugtracker (https://bugs.freedesktop.org/show_bug.cgi?id=80850) this
time using Fedora.

Any help is still very much appreciated.

Regards, Benjamin

Hello,

I'm trying to get a Behringer FCA610 (connected via USB) to work with
PulseAudio on Ubuntu 14.04 (Kernel 3.13). I have already asked for
assistance at the alsa-user mailing list a few weeks back, because back
then I thought my problems were caused by ALSA. As far as I understand
the device works fine with ALSA, but PulseAudio fails to configure the
device properly (see the attached output of `pulseaudio -vv`).

Here is the dmesg output, showing that the device is detected:

[15217.305729] usb 3-1: new high-speed USB device number 2 using
xhci_hcd
[15217.324934] usb 3-1: New USB device found, idVendor=1397,

[15218.722923] usbcore: registered new interface driver snd-usb-audio

Playback of multichannel WAV files with aplay also works:

$ aplay -D plughw:CARD=FCA610,DEV=0 -c 10 Musik/test-6ch.wav
Playing WAVE 'Musik/test-6ch.wav' : Signed 16 bit Little Endian, Rate
44100 Hz, Channels 6
^CAborted by signal Interrupt..

These are the last few lines of `pulseaudio -vv` (as said above see the
attachment for complete output):

There are also a lot of lines containing SND_PCM_NO_AUTO_FORMAT like:

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