New Revision: 37600

Log:
Fix playback with pulseaudio >= 6.0 and multichannel audio

This fixes the message "pa_stream_write() failed: Invalid argument when
sending audio to pulseaudio" caused by pulseaudio commit:
https://github.com/pulseaudio/pulseaudio/commit/150ace90f3808bbb7240e18a11140d66a7bda146
(stream: Fail on client submitting non-frame-aligned memblocks).

Fixes trac #2241
