I am running a Pi4B with a USB Thumbdrive on the 3.0 bus, and USB DDC on the 2.0 bus. It is feeding DACs in a Yamaha Aventage 2060. Before that a HK 520. Thumbdrive is a "high speed" type and has around 630 Cd's worth of FLAC files. I have had about a dozen dropouts of about 0.5sec, all within the last year.
I noticed this first when I was still running Moode 8.x.x and just today got one occurance with 9.3.0 Moode w/ 0.24.2 MPD. This is also a new PI4B with a different USB thumbdrive.
So here comes the crazy part. All of these dropouts occured when I sat the iPad down on the chair and got up to do something!
I have tried to replicate it many times without one success. It only happens when I'm not expecting it. I have never heard a dropout just sitting there. And no, this is not an early April Fools joke. 
Struggling to even come up with a rational scenerio. The Pi and the ipad are on the 5G WAN. The router is not in direct view. It is two rooms over. I thought somehow I was interfering with the 5G, but doesn't really explain why the dropout. I can switch the ipad between 5G and 2.4G while music playing, no issues. I am fairly certain it is not happening on a screen refresh, or wake from blank screen. I've done that many times trying to cause it. It will be a pain to move the router into the same room, but running out of things to try. Also have a new DDC and USB cable coming. The infrequent occurance doesn't help.
Are there runtime logs I can view? Or is that only when that debug is turned on in the System Config menu? and from the warning, might cause its own problems.
