Subject: audio: basic support for multichannel audio
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5c7db3eefeba1cb661c86b2e530ea387319db1d;p=qemu.git

audio: basic support for multichannel audio

Which currently only means removing some checks.  Old code won't require
more than two channels, but new code will need it.
