3.6 External USB audio support for Rally Bar and Rally Bar Mini

From CollabOS 1.11 onwards, Rally Bar and Rally Bar Mini support using a 3rd-party external audio device, such as a USB audio digital signal processor (DSP), as the primary microphone and speaker. This feature expands the use of Rally Bar and Rally Bar Mini to a wider array of meeting room spaces than was previously possible.

When enabled, the 3rd-party external audio device becomes the primary microphone and speaker, and the Rally Bar or Rally Bar Mini built-in speakers and microphones are disabled. Before activating this feature, please ensure that the 3rd-party external audio device can perform appropriately in the room setting, including features such as automatic echo cancellation (AEC), automatic gain control (AGC) and background noise suppression (NS), as CollabOS audio processing capabilities are disabled when a 3rd-party external audio device is used.

Frequently Asked Questions

  1. Will Mute Sync and Volume Control work?

  • Yes, we have verified that Mute Sync and Volume Control work for BiAmp, Shure, and Q-SYS devices. In some cases, it may be necessary to make changes in the DSP device settings/designer files.

  • For other USB audio devices, these features will work, as long as they comply with the USB HID standard for audio control.

  1. Why am I seeing "This room is not available"?

  • If you see the message "This room is not available," it could be because the built-in microphone and speaker are selected as the default for Zoom Room through Zoom settings or ZDM. Enabling External Audio will disable the built-in microphone and speaker and reboot the device. If Zoom's preferred devices are not present, the message "This room is not available" will appear. To resolve this issue, change the preferred devices in Zoom Rooms settings or Zoom admin portal.

  1. Why is audio processing unavailable on Rally Bar / Rally Bar Mini when external audio is enabled?

  • If you are using Rally Bar or Rally Bar Mini and external audio is enabled, audio processing will no longer be available. The connected third-party audio devices must handle audio processing, such as automatic echo cancellation (AEC), automatic gain control (AGC) and background noise suppression (NS).
