Hi @Kay_Levermann ----- Thank you for the follow up and clarifying that information for me! My apologies for the delayed response here.
Moving forward, I would like to enable diagnostics on your account so our techs can try to get a sense as to what could be causing the issue here. However, may I very kindly ask you to first reproduce the problem and note the time of day when you receive the mentioned error message in the application (i.e "Roon lost control of the audio device).
Once I have a sense of when the error occurs I will then enable the mentioned diagnostics. Many thanks!
