Just received the unit today and so far very happy. NFS mounting works great and the sound quality is excellent.

3 problems though so far:

1. In the WebUI, on the playback screen, selecting the mute button (on the left of the volume slider) caused very loud popping noises making it unusable and a little scary. Will have to use pause for now.

2. Adding web radio stations. The "+Add web radio" select does not always appear on chrome (works fine on Firefox). When I do enter anything into the popup and select "Add", a red error dialog appears which says: "Search error".

3. Tried using multiple Android UPNP players and I can use my media source and play locally on the phone, but the AxiomAir never appears in the list of renderers. Not sure what else to do to debug this one.

Can you tell me if any of these are known issues?
