I have a Bridge wired into the router in my Family Room. In that same room are two Play:1 speakers, stereo paired together (Family Room L+R). In my Living Room, I have a turntable that's connected to a Play:5 via the line-in component (RCA -> 3.5MM). For months I've had this set-up working seamlessly. The Play:5 starts the vinyl sessions, which is then channeled through the Play:1 pair and played in both rooms without issue. Sounded great, loved the setup.
Recently, I had an issue with the Play:5 (out of the blue) in which it wasn't appearing in my app nor was it connecting to my other speakers. Upon troubleshooting that issue with Sonos, the problem was traced back to a faulty wi-fi card in the Play:5 (a known issue apparently), and I was issued a replacement speaker. Bummer but glad they replaced it at no cost. So...now to my issue...
Upon connecting the new speaker, I am now having intermittent audio drop out on my Play:1 speakers when they are paired with the Play:5, but ONLY when playing the line-in audio. This doesn't happen with music services such as a Spotify are played in both rooms, and it doesn't happen from the Play:5 at all. I spent nearly 2 hours on the phone with customer support and while the gentleman who helped me did a much appreciated deep dive into what was causing the issue, I wasn't really thrilled with the solution.
Essentially, after all the diagnostic tests, unpairing/repairing the speakers, trying each speaker individually, disconnecting wifi, resetting the bridge, changing the SonosNet channels, changing the channels on my actual router etc. etc., the solution he landed on was to change the compression for my line-in source from "uncompressed" to "compressed".
I'd really prefer not to degrade the audio quality here, especially when it played for months under this setting with no drop-outs at all. Any solutions? Anything else that can be tested?
Thanks in advance!

Note that in practice it's unlikely you'd be able to discern an audio quality difference between Line-In Compressed and Uncompressed, especially with the relative low quality of vinyl. It's the 3s buffering delay that I found more annoying.
