Learn about the known issues associated with Q-SYS Designer Software version 9.12.0.

Updated at December 17th, 2024

Warning

An update to Q-SYS Designer Software can result in “Missing” peripherals and/or Q-LAN streaming faults in systems based on the Core 5200, 6000, 3100, and 1100. This issue does not appear in systems based on any other Q-SYS Core model. 

At this time, we do not recommend updating any system to v9.12.0 using these Cores. This will be resolved in a maintenance release currently undergoing validation. 

 

Audio Peripherals and Components

FLEX4A amplifier not initializing correctly

Issue: The FLEX4A amplifier may not initialize correctly with 9.12.x. When the initialization fails, the output is corrupted and the behavior is nondeterministic. 

Workaround: Power cycle the unit if the amplifier output is corrupted.

Earliest Reported Version: 9.12.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

 
 

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.

HDMI output stops working after switching HDMI I/O Device Type: Encoder to/from Decoder 

Issue: If you change the HDMI I/O component Device Type property from Encoder to Decoder or vice versa and then redeploy the design, HDMI output may stop working.

Workaround: In rare cases, the affected NV-32-H unit may require a power cycle after changing Encoder / Decoder modes. Unplug the NV-32-H from power for a few seconds and then plug it back in.

Earliest Reported Version: 8.2, which includes all versions of the LTS Branch.

Version Fixed: This issue is under investigation.

 
 
 
 

NV-21-HU

Note

Since the NV-21-HU requires QDS version 9.8.0 or higher, none of the following issues impact any of the LTS branches.

 

NV-21-HU Frame Misalignment

Issue: When connecting an HDMI source to the NV-21-HU HDMI input, the frame may become misaligned. This issue occurs with both hot-plugging the video source and normal AC power cycling.

Workaround: Hot-plug the source until frame alignment is correct

Earliest Reported Version: 9.12.0.

Version Fixed: This issue is under investigation.

 
 

Packet loss when Shift AV and USB Video Bridge are both active on an NV decoder

Issue: Netgear 26G4F M4250 drops packets when Shift AV and USB Video Bridge are both active on an NV decoder.

Workaround: Increase NC camera bitrate to 16 Mbps or higher, decrease Shift AV bitrate to 600Mbps

Earliest Reported Version: 9.8.2.

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.

 
 
 
 
 
 

Control Peripherals and Components

Lua comments and strings are blue in the legacy editor

Issue: In the legacy editor (File->Preferences->General->Script Editor->”Legacy”), Lua comments appear in the same blue color as keywords like if, then, else, local, and do. This makes the comments harder to read, although it doesn't affect functionality. 

Workaround: Use the VSCode editor.

Earliest Reported Version: 9.12.0. This does not affect the LTS (9.4.x) branch.

Version Fixed:  This issue is under investigation.

 
 

Network.Interface call not showing all interfaces when in Emulation Mode

Issue: The script is failing to consistently detect and list all network interfaces.

Workaround: None. This will be resolved in an upcoming release.

Microsoft Teams Room: Loses connection if the device is accessed by hostname and its IP changes

Issue: When the MTR component is configured to connect via hostname, and the MTR compute is scheduled for automatic ,nightly reboots, it is possible that the underlying IP address may change with a new assignment from the DHCP server over extended durations. If the IP address changes does change, the MTR component will lose connectivity to the MTR compute and enter a fault state.

Workaround: A reboot is required to pick up the correct address. This will be resolved in a future release.

Earliest Reported Version: 9.9.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.
