Comment 37 for bug 198453

As noted, running pulseaudio through dmix is almost certainly a bad idea. Which means that, short of disabling pulseaudio by default (not a great idea one week before release as it would leave us with the converse problem of re-testing everything without pulseaudio), any fix for this needs to happen in alsa-lib rather than in pulseaudio.

Leaving the ubuntu-8.04 milestone in place, but in practice we need to get a pretty high degree of confidence, pretty quickly, in any proposed fix in order to get it in on time.
