Since autumn, i am trying to set up an kit hardware+software with BBB for computer-musicians as stomp box, works quite well, after successfully installed it in a long term sound installation (headless): some points short: system: + BBB moved to Debian since this year (good) + USB Audio works fine und better now with kernel >= 3.12 + Network performance works better with kernel >= 3.12 - IO support doenst use device-tree overlays anymore on kernel > 3.8 + an iio-backend for Jack2 to use the internal AD's in jack for processing sensor data in PD ;-))) but tricky sound: + down to 10ms with PD and cheap 8 channel out, 2 in USB soundcard Logilink 7.1 (EUR 19.90) + 5ms with Logilink stereo USB (EUR 3,90) + success with audio-cape (stereo, but too expensive for the quality) - sound quality is normally as bad as on most notebooks, tablets and so on + but with a trick: filtered 5V supply for the USB-card not the USB power it seems to get reasonable quality (They have all the same chips like expensive USB cards: C-Media) I just made a blog on this, but it is not public only for intern usage, if anyone is interested in the IEM-embedded-Sound-Kit (doing some audio over ethernet stuff) i can make it open (after some polishing, especially the english) and release the PD-lib (GPIO,AD,I2C,... interfacing) for these devices. This dev's should also work for Cubie-boards, Wand-boards, UDOO and other arm based boards. mfg winfried PS: Maybe we can start an own thread on this. > On Thu, Mar 13, 2014 at 3:11 PM, Brian Fay <ovaltinevor...@gmail.com> wrote: > > While I'm sure that Dan is right that the UDOO is the better choice for > > USB audio, I do have to say that I've had decent success using my > > Raspberry > > Pi as a guitar effects processor, with the Behringer UCG102 interface. > > > > There's definitely a lot of quirkiness to getting it running... for > > example ALSA gets in an infinite restart loop when attempting low latency > > on pd-extended, but vanilla starts up fine under the same settings.
