Thank you everybody.
If the problem is data congestion along the USB bus, what measures could I take to improve things?
I could install my old Allo BOSS DAC HAT instead of the USB DAC. That would be a useful experiment, I guess.
The problem there is that the bedroom RPi must use a WiFi connection to my network, and installing the BOSS DAC HAT knocks out the RPi3B+ built-in WiFi adapter. I dug up a USB WiFi adapter that should work, but wouldn't that be a sideways move? Which device demands more data I/O throughput from the USB bus, a stereo DAC or an AC600 WiFi adapter?
I had the CPU governor set to On-Demand. I've set it to Performance. We'll see if that helps.
Which cache setting did you alter?
Audio buffer ?
Output buffer ?
Input cache ?
My RPi3B+ has 1GB of RAM.
The input cache on my RPi was set to 128MB (the default). I'll try increasing that to 512MB and see if that makes the clicks/pops go away.
