    In using a USB connection log with the Silicon Labs virtual driver, I'm unable to get audio from the Mac via a CODEC to the rig. Receiving through the 2nd CODEC works just fine. With Audio MIDI Setup, there appears no way to increase the audio level (effectively greyed out).

    This is confusing as I'm basically doing the same thing with a TS-590SG which works flawlessly.

    Appreciate any help!

    I don't what to say and again, I haven't learned anything. This began working on it's own without any intervention from me. Bah!

    USB Audio CODEC is "out" only (0 ins / 2 outs), while USB Audio CODEC 2 is "in" only (2 ins / 0 outs). You won't be able to received audio on the first USB Audio CODEC as the sound isn't flowing that way.

    USB Audio CODEC 2 is "in only" and as with all of the SI Labs chipsets, the audio input level is not adjustable. The audio output level on USB Audio CODEC 1 is adjustable.

    I'm not really certain what the problem is here, other than perhaps a bit of confusion, but I see you got it working so that's good.
