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
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.
