First of all i am very excited about your work!
I have just bought the new audio-gd di2014 - which uses the VIA chip to create spdif / i2s output.
But, when i use it with my bbb board the sound is all wrong with lots of noise and cracks.
When i use it with my r-pie there are no issues and the sound is playing fine.
But i would like to use my bbb instead - mainly because at some point i plan on using the up and comming bbb i2s cape.
Is there a known issue with the bbb and the via chip - used in audio-gd products?
