Hi, no, problem is still present on 5.1 (so is with no simd). It is hard for me to detect it by your sound tests. What I use is always observation by listening to mp3 or movie.
I think it could be driver thing, too. But as I have mentioned in #1, in older Ubuntu, I have fixed this problem by tuning some values (but I do not remember the fixes now:(() in pulse configs (that was golden times for me!)... After new Ubuntu on the way - I have overwritten cfg and now problem is still here. Also, setting tsched=0 options somewhere works for me (except high cpu load), so I think there could be the way... I could record you some audio samples direct from channel by mic - to understand my problem better, but it would probably not help. Reproducing this bug on another PC would be impossible. I am sure, that this problem is caused by my old onboard realtek (or nVidia or what) soundcard and maybe by its drivers. Hmm... but I have friend which has the same motherboard - but does not have 5.1 channels. I think, I will try 5.1 on his PC to eliminate HW problem (and prove driver's problem?). Let you know.
