Roku Ultra loud electrical/buzzing sound when waking from standby

Purchased a new Roku Ultra (4800R) recently and am experiencing a loud electrical/buzzing type sound when waking it up from sleep mode in the morning.  This happens every few days and requires a restart to make the sound go away.  Previously had a Roku streaming stick on this TV with no such issues.  Anyone else having this issue and figure out how to resolve it?

I am having the same issue. Any fix besides unplugging the power and reconnecting?

Yes I am having the exact same issue. Glad to know I’m not alone. Mine is the most recent Ultra. I have two of the previous version with no issues. I have to pull the power cord and completely reboot the device. I plan to contact ROKU for an exchange or return. I have others that work fine.

Same here.  Curious to see what ROKU says about the issue.  Please keep us posted.

Having same issue. Started hitting Roku home button before turning off tv or walking away. Been a few days since Ive last seen the issue. Might be a viable work around until Roku gets around to fixing this.
