There is a generic problem with multichannel devices that only accept being opened with many channels and not fewer, in your case 6 x 10 channels probably. I started working on a patch for that (primarily for the new firewire drivers) but then got busy with other things. The workaround for now would be to write your own profile/path according to this link: http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles/ On 2014-07-03 15:13, Benjamin Tegge wrote: > Hello everyone, > > Somehow my message from earlier either didn't make it to this list (too > large attachment) or didn't receive any replies.
