Hey Pierre,
Not sure if the 2 are related but presuming they are... I've just been testing an ESI UDJ6 soundcard and the image I backed up before updating the firmware would only run the card with the usb and ethernet slowdown options. Post rpi-update got 6 channels of audio without either slowdown required though I think it does run better (less system resources) with both options enabled.
My trusty ol' Griffin just 'works' with both installs so didn't notice any difference but I haven't yet checked whether usb slowdown is still required for duplex with that soundcard as of yet.
This is on a rev1 256meg board btw.
Regards,
Julian

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
