Hi @Jared_Rodeheaver,
Thanks for reaching out to us to ask about this issue. If you quit Roon and then restart it does it immediately start using a high amount of the CPU or does it take some time to reach that level? Also are you seeing any slowdowns in Roon’s performance when this happens?

When I restart Roon the CPU usage does go down at last for a while but it doesn’t have a consistent behaviour. Sometimes the CPU usage will spike within minutes of a restart and other times hours later. There is no correlation to performance issues that I can tell. I do have intermittent times when it claims network performance is an issue when using Qobuz but since Qubuz works fine nativity and all network tests are good I think this is some issue with Roon. Let me know if I can provide any other info or logs etc. Thanks!

Note this only seems to happen when bluesound nodes are my endpoint.
