This feature is currently being deployed with an expected completion by January 2022.
When the feature is available on your Teams client you will be able to use high fidelity music, meaning you will be able to have a richer sound experience.
With this mode Teams will support a 32 kHz rate at 128 kbps if you network bandwidth allows it.
To turn it on, access the Settings\Devices menu
If you can’t wait to get it you can switch your Teams client to use the Preview settings – if your Teams administrators allow it
