I am experiencing some occasional Telepresence Sound Check errors from a few different Telepresence Room Kits.
The soundcheck produces the test tone music, which can be heard. At the conclusion, sometimes it indicates a successful test, other times it indicates an error that the volume may not be loud enough for the test. This result is intermittent (sometime pass, sometimes fail), regardless of room speaker volume. Starting a video conference with a room peer always is successful for both bi-directional audio and video, without further action on microphones, room audio volume, etc.
Could someone direct me to the appropriate documentation regarding the "sound check"? I am interested in any optimization strategies to eliminate nuisance failure warnings, when things are working properly.
