Just to clear things up, with a clean install of ubuntu, stereo sound is perfect. however, in 5.1 mode, I hear high pitched rattling sound, just like this bug reports.
When I install your patch using your script or your PPA in my source.list, stereo stays fine, but 5.1 gets worst. See below.
First thing I did on another clean install was to clear everything in my source.list so that I only install stuff from your repository. Not even official updates, so we start from an easy common point.
then I did what's in the attached file. (remove all repositories from source.list, add only yours and start an upgrade: pulseaudio gets updated)
Then I play desktop-login.ogg and it plays fine because PA is in stereo mode.
Then I set PA to 5.1 surround. The file doesn't play except for a continuous loop of 10ms or so which won't stop until I move PA main volume slider. The same happens with ubuntu's default "beep" sound. Looks like a buffer problem which gets emptied when I move the volume slider, I don't really know...
At this point, I didn't install any more software. Not even updates. Unless you need further testing on my current setup, next step for me would be to start a fresh install again and try the no_simd thing manually as described earlier in this discussion. Sorry I didn't try it before as it's known to only lessen the problem. Well, at least if I do this now, we'll also know if your patch has anything to do with my new problem. Hey it's a new problem! I was getting bored with the old one :P
Oh and just so you know, it takes about 10 minutes to reinstall clean so it's easier and faster than trying to undo everything.
