Hey Pierre,
Not noticed any particular change in performance as of yet though my Pi is in a constant state of flux.
My limited understanding is that the updated alsa driver now has direct access to the Pi's audio hardware rather than a software workaround where access to the audio stream was routed through the gpu, this *should* trim some latency.
On my rev1 board I only use alsa but the rev2's have jack though haven't updated those ones yet.
Will let you know if anything noticeable pops up.
Sorry can't be more specific.

hi Julian,
Could you please tell us what difference this makes in terms of performance ? Do you use JACK ? Is this any better than with Pd only ?
Cheers,
Pierre.

Thanks to Dan for the 'update alsa mmap' command' Thought I'd buggered up my install until I ran that command, now all happy again.

Hi all,
Dunno if everyone's on this already but looks useful:

Not tested as of yet but anything that squeezes a bit more audio performance out of the RPi is to be welcomed.
rpi-update ahoy,
Julian
