Hi all -
I just now tried again (after some months of not fooling with it) and got audio in+out working with no trouble at all... from a clean and recently updated Raspian install (i.e. 'apt-get update; apt-get upgrade) I just deleted pulseaudio: apt-get remove pulseaudio and then slowed my USB down to 1.1 speed by adding the setting: dwc_otg.speed=1 to the file /boot/cmdline.txt plugged in a Griggin iMic (bout $25 I think) and immediately got full-duplex audio. I'm running only one channel in and tried it with an electric guitar with the iMic switched to 'mic in' and all worked. I was able to get audio latency down to 10, didn't try any lower than that.
This is all without any mouse, keyboard or video monitors connected to the pi - I'mm SSH-ing in. Last time I got up to this point, things started to degrade when I put other USB devices on so I'll try that now...
cheers Miller

Yes, I got it goiing for a recent workshop in Nantes ALSA tweaked a bit with the .asoundrc file Hardware: Turtle Beach dongle (Old Amigo 1 I think) Latency: 150ms (total suckage)

Apologies for dragging this up again...
Can anyone confirm that they have got duplex audio working - in any form with any combination of hdmi, usb or the regular audio out of the rpi, and with which OS, version, tweaks?
Still not convinced it's properly doable from our (iMic USB based) experiments.
Regards,
Julian

Thanks, all. I'll check out the iMic & UCA222. Cheers! -- Dirk

in fact, both edirol UA1X and beringer uca222 works. they look so similar that I mix there name. sorry Cyrille Le 04/01/2013 18:55, Pedro Lopes a écrit : edirol? Isn't uca222 a behringer card?

The thing looks like an apple product but (as I discovered today looking at it) isn't. Good job of apple-style-imitation-without- __infringing-trademark. The other USB 'adapters' also worked but beware - some take more power than the Pi can supply and some are physically so bulky you can't get anything in the other USB slot - in either case you have to get a powered USB hub and live with a layer of additional uncertainty. cheers Miller On Fri, Jan 04, 2013 at 08:18:00AM -0800, Dirk Myers wrote: Folks: I've been digging through the list & searching, haven't found a clear answer: what are folks using for audio output from the Raspberry Pi to a mixing board? I'm leaning toward trying a few USB audio interfaces. Curious about what others have used that is working well.
