When running a game under WINE pulseaudio is showing a constant delay of what I would estimate to be 100-200ms that on occasion climbs to over 500ms. I can't put my finger on why it increases on some instances, though.
I run Xubuntu 13.10 on a 1st (or 2nd generation?) i7 with plenty of RAM and CPU load is not high at all. All games exhibit this behaviour. Haven't messed with pulseaudio's configuration.
I should also say that I haven't noticed any lag or synchronisation issues when playing video files.
How can I go about diagnosing and potentially fixing this annoyance?
