Same problem here.
I have the 5.1 Roku wireless audio setup (Streambar Pro, 4 wireless speakers & the wireless subwoofer) and a TCL Roku TV. Immediately after getting the 11.5 update, I started having issues. The next day my speakers updated to a newer version and the issues seemed to go away for a bit. Yesterday it started happening again.
For me, the audio will clip in and out. Sometimes for extended periods of time, sometimes for just a second or two. It can affect any of the speakers or the subwoofer and may impact just one speaker or multiple speakers. I'm not sure if it's affecting the Streambar Pro. I've noticed on one occasion when checking in the settings the speakers & the subwoofer may appear as (disconnected). The audio issues happen on both Roku apps played directly on the Roku TV and through connected streaming devices such as an Apple TV or an Xbox. I would guess it's a connection issue between the wireless speakers and the Roku.
All devices are fully updated and/or show no updates available. I've power cycled all the devices (including the streaming devices) both via the menus and by physically unplugging them.
