For a USB interface that does balanced audio, I've had good luck with the following:

I'm testing one right now on an Intel NUC running Rivendell. The output levels seem awfully low; I'm not sure why.
A 1 Khz tone played on rdairplay at the level indicated as nominal comes out of this adapter at -10 dBu, measured with a VOM with no other load. That's with the volume turned up all the way in alsamixer.
This adapter is not capable of +4 dBu output. Its output does appear to be balanced, though.
I did not test the input to see how it handles a tone at +4 dBu. Rob _______________________________________________ Rivendell-dev mailing list [email protected] http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
