Glad to hear I'm not alone on this, Nick DiFeo. For what it's worth we're also running Lenovo SRS units and they work fine, it's just Surface Pros which are experiencing the issue with non-responsive touch screen / freezes.
It sounds like your experience is identical to our's. I've been monitoring the thread count for the SRS app and it seems there's something odd going on.
The moment the thread count started rapidly increasing, the app became unresponsive, the dip is where I initially rebooted it then it crashed again afterwards and had to be rebooted.
From looking at the trace logs I can't find anything that jumps out as potentially useful other than this:
06/11/2018|12:15:00.523 1D00:1E7C INFO :: CUccMediaDeviceManager::DeviceRemoved - Device was removed: id=2812440981328 name=[SyncMaster (Intel(R) Display Audio)]
06/11/2018|12:15:00.523 1D00:1E7C INFO :: CUccMediaDeviceManager::FireTelephonyDeviceCollectionChanged - Telephony device was removed type=0x4 name=<[NULL], [SyncMaster (Intel(R) Display Audio)]>
I've looked at 4 trace logs today and 3/4 had this event right when the crash occurred.
I can provide these logs to David or anybody else at Microsoft if they are interested.
On an unrelated topic (but more relevant to this thread), we're having issues with HDMI ingest on a Surface Pro 2017 unit with SRS 3.1.112.0. A staff member is doing HDMI ingest and presenting their screen and they experienced poor framerate and audio issues. This is only a single display unit.
Our monitoring for that unit showed the CPU utilisation stuck at 100%.
