'Twas brillig, and Lennart Poettering at 06/01/10 13:18 did gyre and gimble: >> I stumble into it almost every day ?

I still see this too, but not for the full duration of the louder sound, just at the fringes - e.g. when it starts and when it ends. We discussed the problem a while back Lennart and you reckoned it was something that wasn't going to be solvable at the time. It's noticeable with music volume set to e.g. 17% and event sounds set to 100%. Testing just now it's much better than I remember it being in the past, but still definitely there and quite obvious.
