USB audio on VF3000-L33-AVS
Posted: Sat Apr 21, 2018 9:16 am
Hi, I'm trying to get USB audio working from a VF3000-L33-AVS dev kit. I understand that the device should just plug in and show up as USB speaker and microphone.
I flashed firmware from here - http://www.xmos.com/published/vocalfusi ... ion=latest - as it didn't seem to come with any on by default. I have tried 1i1o2_lin33_asr and 1i2o2_lin33_48khz. After both of those, I can see the device show up as speaker and microphone on my mac and a linux device - however, when trying to play sound through the output device, nothing can be heard. I also noticed that alsa mixer AND mac system preferences said there was no mixer capabilities (output controls on mac) with the output device, so I wondered if that was related?
A lot of the instructions on the site talk about building firmware, but that doesn't seem possible at the dev-kit stage, so I was left a bit confused. I guess my question is - what's the best firmware to flash on to a VF3000-L33-AVS dev kit to get USB mic and speaker working and could you give me a direct link please?
Thanks,
Steve
