Hi @Hectorson ----- Thank you for the report and sharing your feedback with us. The insight is appreciated!
Moving forward, to help aide in our evaluation of this behavior may I very kindly ask you to please provide the following:
An expanded description of your current setup using this link as a guide.
My assumption is that there are no issues when the sample rate stays consistent between tracks, correct?
Are any other audio zones experiencing this behavior or is it just the SBT + Meridian speaker zone?
Can you please provide screenshots of your signal path leaving Roon when you notice this behavior and all the playback settings being used in the application.
