Teams Room Audio

Dear @Jim Monk,

Based on the details you shared, this behavior is expected: Teams will auto-detect and pre-select “Room Audio” by default in BYOD meeting rooms to make it easier for users to join with the room’s shared peripherals.

You can refer to this article: Microsoft Teams: Auto-detect and pre-select room audio in BYOD meeting rooms - M365 Admin

That said, there is a workable alternative, please note it requires each user to configure it on their own device:

Workaround (user-by-user setting):

Open Microsoft Teams > Settings and more (…) next to your profile picture (top-right).

Choose Settings > Devices > under Audio devices, select your preferred Computer Audio device for both:

• Speaker, and
• Microphone

This helps ensure Teams defaults to Computer Audio rather than Room Audio for that user going forward.

Configure the room so Teams consistently uses the desired conferencing devices and avoid fallback to “Room audio” by setting the audio peripherals explicitly and ensuring only the viable devices remain active.

Use these steps on the Teams Rooms device (or via the Pro Management portal if available in the future):

1. On the Teams Rooms console, open Settings → Windows Settings and sign in as administrator.
2. In the Teams Rooms app settings (or in the Pro Management portal when licensed), explicitly set:
   • Conference Microphone = the Yealink conferencing microphone
   • Conference audio speaker = the Yealink speaker device These fields control which devices are used for meetings and help prevent Teams from selecting non-viable “room” endpoints.
3. Verify that no other low‑quality or non‑viable audio devices are active:
   • In Windows Control Panel → Hardware and Sound → Sound, on both Playback and Recording tabs, disable any onboard or console speakers/mics that should never be used for conferencing.
   • This reduces the chance that Teams will fall back to those devices and present them as “Room audio.”
4. If audio quality is poor or the mic appears muted when it is not, disable audio enhancements on the conferencing device:
   • In Control Panel → Hardware and Sound → Sound → Playback tab, select the Yealink device → Properties → Advanced → under Signal Enhancements, clear Enable audio enhancements → OK.
   • Repeat on the Recording tab for the same device.
   • Restart the Teams Rooms device.
5. If the device ever shows as Unhealthy in a management portal, check cabling, power, and firmware for the Yealink device, and avoid unsupported USB extenders. A missing or unstable device can cause Teams to switch to other detected “room” audio options.

Once the conferencing microphone and speaker are explicitly configured and other devices are disabled, users can continue to click Join now and the room should consistently use the correct “Computer audio” path even though the hardware is the same.
