If you have a problem with a specific card then there are essentially 
two possibilities:

1) The alsa level driver sis providing incorrect timing information to 
PulseAudio and as a result messes it up. You can work around this to a 
degree by passing tsched=0 to module-hal-detect (it's an ugly hack and 
the correct fix is to correct the bugs in the alsa driver).
2) The mixer path is not correctly interpreted in pulseaudio. A more 
flexible mixer logic has been introduced in pulseaudio 0.9.16 to address 

Overall, without seeing any actual debug info about the problem you're 
having, I'd guess at 1.

Well, those patches on that branch are recommended to distro packagers, 
so regardless if it fixes this bug, if someone is shipping 0.9.15 then 
they should be applied.
