Audio Peripherals and Components
Softphone not responding to 407 requests after a BYE message
Issue: Symptoms experienced will show that when a call is made from the Core and a hangup is made from the Core, the call will not disconnect. If the call is disconnected from the far end then it will disconnect properly. Sending a BYE message results in the system sending a 407 request, which the Softphone does not respond to.
Workaround: Hanging up from the Softphone or far end caller works, but not from the Core.
Earliest Reported Version: 9.9.0. This does not affect the LTS (9.4.x) branch.
Version Fixed: This issue is under investigation.

USB-C Audio Requires USB Soundcard
Issue: When a Generic AV Source is connected to the NV-21-HU’s USB-C input, the Audio Channels are set to zero and grayed out. The USB-C input does not support audio via the DisplayPort alt-mode path.
Workaround: To enable audio via USB-C, a USB Soundcard must be added to the design. This requires activation of a Q-SYS AV Bridging License. For more information on the workaround, visit Routing Audio Using USB Audio Bridging or see example design below.
Earliest Reported Version: 9.8.1
Version Fixed: This issue is under investigation.
USB Bridging
Intermittent Mediacast video freezing during camera switching
Issue: The Mediacast video feed freezes randomly when switching cameras using the gooseneck audio input. The video output shows as offline in Zoom, although the cameras appear functional in Configurator.
Workaround: Reboot the core to restore functionality.
Earliest Reported Version: 9.10.0. This does not affect the LTS (9.4.x) branch.
Version Fixed: This issue is under investigation.
Intermittent camera switching issues in Dividable Room System
Issue: You may experience inconsistent camera switching behavior when alternating between ‘Divide’ and ‘Combine’ room states on the UCI of an MTR. The issue manifests as black squares instead of camera feeds, delayed image updates, or incorrect camera feeds being displayed despite different selections.
Workaround: A temporary fix is to use a single camera preview on a common layer accessible by both ‘Divide’ and ‘Combine’ states, which seems to resolve the issue. Additionally, ensuring that the Mediacast Router component does not display actual images of the attached cameras on its buttons may help.
Earliest Reported Version: 9.10.1. This does not affect the LTS (9.4.x) branch.
Version Fixed: This issue is under investigation.
Cameras
Peak Frame Bitrate control synchronization
Issue: The Peak Frame Bitrate Control does not stay in sync between the USB Video Bridge and the selected camera. When the Peak Frame Bitrate control is manipulated in either the bridge or the camera component, the corresponding control in the other component does not change as expected. This issue has been observed with a 100% frequency on build 9.12. The workaround is to adjust the Peak Frame bitrate at each camera control instead of on the bridge.
Workaround: Adjust the Peak Frame bitrate at each camera control instead of on the bridge.
Earliest Reported Version: 9.12.0. This does not affect the LTS (9.4.x) branch.
Version Fixed: This issue is under investigation.
