If anyone uses a Bluesound Node, a recent software update may cause dropouts- it did in my case. ‘Audio Clock Trim’ was added as a default under audio in the settings menu. I turned it off, and it solved the issue.
It appears to have something to do with using an external DAC, though I’d be lying if I said understood their explanation.
I’m just throwing this out there for any that may have experienced this- it was quite annoying for me; I stumbled upon the solution out of frustration.
