I have had skipping issues with Roon since day 1.
I’ve experienced this with Qobuz, Tidal and external drives (different drives).
I’ve experienced this with different cores MacBook Air, a purpose built PC which runs nothing but the Core.
I’ve experienced this with different routers, both WiFi and hardwired set ups.
I’ve experienced this with different broadband providers.
It drives me mad.
Sorry to hijack your thread. I hope you find a solution.
If there was a decent alternative around I would give up my lifetime subscription just to solve this issue.
