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 On Fri, Jan 18, 2013 at 01:27:46PM +0100, Cyrille Henry wrote: > hello, > > could you tell a bit more about the alsa tweak? > > thanks > Cyrille > > > Le 18/01/2013 12:06, [email protected] a écrit : > >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) > > > >On 18 January 2013 at 10:49 Julian Brooks <[email protected]> wrote: > >>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 > >> > >>On 5 January 2013 17:54, Dirk Myers <[email protected] > >><mailto:[email protected]>> wrote: > >> > >> Thanks, all.
