Hi, Josh!
Thanks for the quick reply.
I used linux out-of-box. Just plugged the USB cable into PC and used putty to connect to root console. Then I tried to call arecord. I did not change anything at first. However, I called alsactl init at one of my tries.It started to re-configure alsa core, but nothing changed.
Well, I participate in this project mostly as a hardware engineer/designer. Now I just want to check AIC connections so that I could give the kit to my colleagues who will prototype the full application. So, for the first demonstration the simple test will be enough: I plug one end of 3.5 mm audio cable into PC headphones jack then plug another one into AM335x kit line1 jack, record some wav played by PC. Then I switch mixer to line2 and record second wav form PC. The I play them both, one after another, to see they sound diffrently according to input lines. If this works, I would start drawing target schematics while programmers will evaluate end application, in parallel, having closer look on linux SDK, ALSA, etc.
Best regards, Vladimir...
