I've recently installed a2dp packages on my N810 and that is working pretty good, unless I try to use anything else on the tablet at the same time. :( But even when the tablet was idle, I mean just Canola playing music, I've had quite frequent, short skips of 1-2 secs - really annoying.

Today I've installed dsp-sbc tough (great stuff, lardman!), CPU usage dropped to almost-zero, and to be honest there are significantly less drop-outs in the 'idle' mode, but then it seems like it's way more sensitive to any other activity - event sliding the keyboard up/down, or locking screen and keyboard with slide button results in drop. :-o (which is quite strange, as CPU is almost not busy at all, so such tasks should have no effect...)

The only thing I didn't do tough, is flashing that custom kernel image provided with dsp-sbc. I've read release notes and I know it gives the ability to tweak CPU/DSP speed, but are there any other improvements and/or changes than that?
