Issue: Using a Core 24f in I/O-Core 24f mode currently incurs an additional 1.75 mS of latency, round trip.

Workaround: This issue is under investigation to be resolved in the next maintenance release.

Earliest Reported Version: 10.0.0.

Version Fixed: This issue is under investigation.

Issue: Under high-frequency serial traffic (e.g., tick rate ≤ 0.1s), the QIO-FLEX4A peripheral intermittently loses its reservation and reports an error, “Missing - In use by another design.”

Workaround: Avoid using extremely low tick rates (e.g., 0s or 0.1s). Increasing the tick rate to 1 second or higher appears to prevent the issue, even with large payloads. Customers should stress-test serial communication before updating to 10.0.

Earliest Reported Version: 10.0.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

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.

Issue: When the PL-DC8 is set to biamp mode with a 125Hz crossover, the high-pass filter is missing in both Default and Flat modes. This results in incomplete filtering for the high-frequency path. 

Workaround: A corrected Lua file is available and ready for use. Applying the updated Lua resolves the missing filter behavior. In the meantime use the 80Hz or 100Hz crossover.

Earliest Reported Version: 9.10.1. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

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

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

Earliest Reported Version: 9.7.0. This does not affect the LTS (9.4.x) branch.

Version Fixed:  This issue is under investigation.

Issue: Using the TSC-G2 touchscreen controllers with any multi-gigabit switch may show "Offline" and/or "No Link" when checking the test screen.

Workaround: Connect the touchscreen controller to another switch and downgrade to QDS version 9.10.1.

Earliest Reported Version: 9.10.2 and 9.4.7 LTS.

Version Fixed:  This issue is under investigation.

Issue: The 2nd page experience is incorrectly shown on the UCI when joining a Zoom call.

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

Earliest Reported Version: 9.10.0 and 9.4.6 LTS. 

Version Fixed: This issue is under investigation.

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.

Issue: Custom Font Styles are not applied properly for the Controls & Tools via UCI Style Controller.

Workaround: Specify different font-family names for your imported @font-faces.

Earliest Reported Version: 9.8.2 and 9.4.5 LTS Branch.

Version Fixed: This issue is under investigation.

Issue: If a design schematic contains a Call Sync component and the Core Model is changed to 'vCore Control', the Call Sync component remains enabled while any wired Call Systems or Endpoints become properly disabled (grayed out).

Workaround: None. Call Sync is not supported with vCore despite not showing as disabled in designs that use vCore.

Earliest Reported Version: 9.6.0 and 9.4.4 LTS Branch. 

Version Fixed: This issue is under investigation.

Issue: When opening a design file saved in previous versions to 10.0 - TSC USB A/V bridge is disabled and removed from inventory, but component is still accessible and can be used in schematic causing distorted audio.
Workaround: While the file is opened in 10.0, delete the USB bridge components from the schematic.  Select the TSC in the inventory and (re)enable the USB bridge components in its properties. Go back to the inventory item and drag the USB components back into the schematic.
Earliest Reported Version: 10.0.0.
Version Fixed: This issue is under investigation.

Issue: When clicking the Reflect Sign Out link, the “QSC ” webpage is opened and the QSD instance remains signed into Reflect.  Further clicks will only open more QSC  pages.

Workaround: With an instance of QSD 10.0.0-2505.007 actively signed into to Reflect, open a QSD 9.13 instance and click its ‘Sign Out’ link (This forces the 10.0 instance into an actual signed-out state, although the 10.0 instance still reads ‘Sign Out'). At this point, clicking the ‘Sign Out’ link in the 10.0 QSD instance will change it to ‘Sign In’

Earliest Reported Version: 10.0.0.

Version Fixed: This issue is under investigation.

Issue: Core processors can unexpectedly reboot when receiving audio from DVS NICs that are also sending/receiving out large volume of traffic.  (The core will automatically recover per @Fernando Nieves Marrero )

Workaround: If possible, limit the amount of bandwidth being used by the DVS NIC while sending audio to a Core (speed tests, large files transfers to/from the core, etc)

Earliest Reported Version: 9.13.0

Version Fixed: This issue is under investigation

Issue: When upgrading vControl core firmware from versions 9.12 or 9.13 to 10.0, the process fails with the error: "Login failed: License start date not yet reached. (Error Code: 210188)".

Workaround: Rebooting the vControl core after encountering the error resolves the issue and allows the upgrade to proceed successfully.

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

Version Fixed: This issue is under investigation.

Issue: Enabling the Secure Communications and Trusted Peripherals feature for larger systems (more than 64 Peripherals) may result in the Core becoming unresponsive and undiscoverable by Q-SYS Designer.

Workaround: At this time, we do not recommend enabling this feature on systems with more than 64 Peripherals. 

Version Introduced: 10.0.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This limit will be removed in the next patch release

Issue: When connecting an HID device to USB A, Port 1 on Core 24f, the device connection is not indicated in the USB In component but does function. Port 2 is not affected and indicates its device connection as expected.

Workaround: None. This will be resolved in a future release.

Version Introduced: 10.0.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

Issue: The HID component stops working with the G7500 when HID Keyboard or HID Media blocks are included in the design.

Workaround: To resolve this, remove the HID Keyboard and HID Media blocks from your design.

Version Introduced: 9.10.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

Issue: The 'Verify Validity Period' checkbox in Peripheral Manager erroneously accepts clicks and displays a "Security options saved" message, even though it should be either grayed-out or absent in the 'Secure Communication' tab for QIO, NL, and NM Series devices.

Workaround: None.

Earliest Reported Version: 10.0.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

Issue: When accessing Q-SYS Peripheral Manager (QPM) from a web browser, some connections may remain open, resulting in excessive polling of certain status URLs.  This excessive polling may cause timeouts for other web responses from a QIO, NL, or NM, series device. This may impact QPM performance and the device’s ability to support the Trusted Peripherals feature, resulting in authentication issues between the Core and the Peripherals. 

Workaround: Do not leave QPM connections open and close browser windows after logout. Refresh the browser if a connection times out.

Earliest Reported Version: 10.0.0. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.

Issue: If you rename a Q-SYS device, both the original and new name can sometimes appear in Configurator.

Workaround: Close and re-open Q-SYS Designer Software. This will be fixed in a future release.

Earliest Reported Version: 9.7. This does not affect the LTS (9.4.x) branch.

Version Fixed: This issue is under investigation.
