Intermittent audio after startup. ‘20 AT4

[ForkliftJeff]

I’ve had my 2020 AT4 for a few months now and occasionally right after startup I will get intermittent audio for about 30 seconds. It’s happened on all sources (usb, radio, Sirius, iPhone over Bluetooth).  Everything else seems fine I can even watch the time of the song keep going and even pause while I can’t hear anything. Always clears up after 30 seconds or so.

Nobody else having this issue? It’s happened a few more times. I have noticed a few times while it does it it shows “media indexing”. I think it says that when I’m on USB. I was wondering if it might have something to do with my 32GB USB stick full of music.  Maybe too much info for it to read while the radio is starting up?
