Currently only usb-audio frontend and alsa and pa backends are updated. Using more than two channels requires turning off mixeng (-audiodev backend,id=foo,out.mixeng=off,...). Currently you have to specify the number of channels you want to use when creating the usb-audio device, see the last commit for details. To do this I currently dynamically allocate the whole USBDesc structure, which looks ugly. If there's a better way, please let me know! These patches requires my previous -audiodev patches: https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00827.html Please review.
