[Qemu-devel] [PATCH v2 0/9] audio: multi channel audio support

[Kővágó, Zoltán]

This patch series adds support to more than two channels of audio (5.1,
7.1, etc.).  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,...).

For backward compatibility reasons, you have to specify multi=on when
creating the usb-audio device:

  -device usb-audio,id=foo,multi=on,...

Please review.
