Comment 3 for bug 1496577

I'm also hit by this bug. Mainly when I'm playing games and Youtube at the same time.

From journal:
pulseaudio[6323]: [alsa-sink-USB Audio] xmalloc.c: Assertion 'size > 0' failed at pulse/xmalloc.c:60, function pa_xmalloc(). Aborting.

backtrace:

Since there seems to be a fix upstream can we merge this into Ubuntu 15.10?
