Hello @Peter_Overbosch,
Thank you for the detailed description — the behavior you’re seeing (the endpoint disconnecting/reconnecting when selecting a new track, then eventually stabilizing) is very similar to a known issue introduced after the 2.58 update, particularly affecting some Roon Ready devices.
There is an ongoing investigation into this behavior, and based on current findings, a ROCK reinstall does not reliably resolve it, which would also explain why your OS reinstall attempt did not help.
We’d like you to please review this community thread and check whether your experience matches what’s described there:
