Difficult one. Unless it has solved itself during one of the updates

Here is the log.
I don't know how closely you'll be able to follow what I did, but in
case it helps:
1. I started PA for logging, and started Banshee.
2. I then started playing a high-quality netradio stream.
3. The sound at this point was only coming out of a couple of channels, so I
There are a few strange things in that log, e g these:
E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was

E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_emu10k1'.
Please report this issue to the ALSA developers.

Installing that had no effect.
I hold to the assertion that the bug *must* be in PulseAudio: If I

sounds *just* fine. The only problem is that most ALSA applications do
not output 5.1 channels directly, and PulseAudio is
ALSA works just fine by itself. ALSA has _never_ been the problem.
There is no squal or high-pitched whine when running your test, and the

pasuspender -- speaker-test -D plughw:0 -t sine -c 2 in a terminal? If
it does not work (i e two alternating tones, alternating left - right),
it is more likely to be an ALSA problem.
