Re: [PD] Raspberry Pi USB2 audio fixed (apparently)
OK. For your information, pulseaudio doesn't come with the new version of Raspbian apparently (I couldn't remove it cause it wasn't there !). No idea why. Pd seems to work a little bit with my soundcard, but after a couple of seconds everything freezes. I'll try with no gui in the coming days. Cheers, Pierre. 2013/7/3 Julian Brooks jbee...@gmail.com 'off Millers site' not 'of' And also another thing with the power supply. Although 1a is supposed to be fine 2a actually works really well if you're driving any peripherals, giving plenty of overhead.

I also found that powering off a 2amp 5v usb hub gave dramatically better results. Full duplex two channels at 44.1khz without dropouts. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Raspberry Pi USB2 audio fixed (apparently)
Hey Pierre, Damn that's rubbish! Have you checked that pulseaudio is uninstalled? Also try: sudo rm /etc/asound.conf My understanding is that after the recent also fixes the asound.conf is redundant and can cause issues. 1st couple of options that spring to mind (also feel bad for promoting possibly duff info:( Hope you can sort it, Julian On 2 July 2013 20:52, Pierre Massat pimas...@gmail.com wrote: Hi all, I did a fresh install of Raspbian using the NOOBS installer.
