BTW.

The good news first. The 2048:2048 buffer setting works, even with
24/96.

It seems that it is the bulk-data-buffer-load at the beginning of a
track -- when using rather huge streaming buffers and high samplerates -
that's causing task scheduling issues on a low steam machine like the
PI.

It seems that the playback gets messed up if SL  with the its rather
high playback priorities (default=45)  gets in trouble with the priority
scheme of other involved services and IRQs. 

On my Arch installation not any other service/interrupt seems to be
elevated. E.g. on the SB Touch it's different. Pretty much all relevant
services and interrupts are elevated to 40 by default. 
SL is slightly above that. That's presumably causing less priority
issues on SBT. That's my experience at least.

Anyhow. It seems that I have to have a closer look at my task priority
scheme of the RPI, if I want to run in full-file-buffer mode. 

And lets stop the guessing. I'll also do a bit of debugging. ;)


Cheers
