Hi Mikel,
I’m encountering the same problem, but my error is pcm_read:2152: read error: Input/output error.
Could you have any progress? Btw, I’m using beaglebone black, and I still can’t make it work. I’ve also modified the codec, compiled a kernel and configured ALSA paramaters as detailed in this discussion.
I really appreciate it if you could share some of your experience with this.
