[meta-xilinx] Sound issue

[Mike Looijmans]

I guess you'll have to dig a bit deeper into alsa to find the issue. There are 
too many things than can go wrong here. The drivers support a limited set of 
formats, so start with 48kHz, 32-bit stereo.

As for meta-topic, I know the audio works (both hdmi and adau) if you build 
that design with the master OE branches. I cannot speak for other forks and 
layers.

Mike.
