Looking at the code, it seems like unnecessary changes should already be avoided (?)
The following is the console output when I skip to the next track in this album
Not totally sure what's happening here, there seem to be two detections with both 16 and 24 bitDepths based on the Apple Music logs

fwiw I tested that album and couldn't repeat the error (v1.1/b11)

I imagine some DACs handle sample rate resets more gracefully than others without dropouts.
It seems like LosslessSwitcher is doing something on every track change on this album on my system but I haven't worked out what exactly

thats the thing, no change happened, because they're all 44.1
the dac I was using actually has a noticeable dropout usually, with a physical click on changing. No changes or system confusion for me.

I found one particular repeatable sample rate change (but not reset): when adding tracks to "play next" it switches the sample rate to that of the new track

I can confirm the excessive switching - using an M Track 2x2 and M Audio AIR 192 4, as well as my Built-in Macbook Pro M1Max DAC.
It causes more like 2-5 seconds of total dropouts for me, switching often more like 2 or 3 times between sample rates, I have bit depth switching deactivated.
I can also confirm switching fairly early (too early) to another sample rate when the upcoming song has different properties, something like 2-3 minutes of playback too early.
Lmk how I can provide some logs, if needed! :)

I use a Fiio Q3 and at the start of every song it drops out for 1-3 seconds even when there isn't a switch (listening to an album rather than random songs)
Also happens whenever I drag the slider to another part of the song (forwards and backwards)
As soon as I quit the application and skip song/drag slider the issue goes away immediately.
