The problem is not your configuration, it is the motherboard.  I have 
tried that exact same motherboard and it just will not work.  I think it 
is the NM-70 chipset, because I had another motherboard using the exact 
same chipset with the same problems.

The simples solution is to get a different motherboard, e.g. the Atom 
using the NM-10 chipset.

What you will find with the problem motherboard is that the alsa utils 
such as aplay and alsa-mixer works perfectly.  You can play audio to the 
URIx using aplay (connect up powered speakers to the audio out pins). 
However, neither Asterisk nor uridiag will correctly output audio.

I have spend weeks trying to diagnose exactly what the problem is, 
inserting diagnostic prints in both uridiag and the chan_usbradio code, 
but I have not been able to figure it out what the issue is.  The mixer 
settings seem to get set correctly, but the audio ends up nowhere.

If you simply get a different motherboard, you could download your exact 
same config and it will work perfectly.  I tried that with my node on five 
differnt computers, and the two using the NM-70 chipset would not work, 
and the other three using differnt chipsets worked perfectly.

If somebody DOES figure out what makes this motherboard (or chipset) 
whacky, I would love to know, but my advice is to repurpose that 
motherboard and get one NOT based on the NM-70 chipset.
