Ok, I've done a few tests with ogg/vorbis.
On the raspberry pi (non-overclocked) the use of ogg/vorbis basically
pushes the CPU to 97-100% and the audio is totally unusable. I tried both

Sure thing... I won't have a chance to play with it for a couple of days,
but I will report back when I do.
I've also just received an OLinuXino A20 embedded sbc, which is quite a lot
more powerful and as an on-board audio device.. I've just got it booting
linux so will be running some tests on th
Hi Matt,
Congratulations to your work!
Could you please additionally benchmark with ogg/vorbis?
I would be interested in the results.

If you make your logged-in user a member of the audio group, you can use
rtprio, memlock and nice as shown here:

Cool, sorry it had to be so painful..
