While the bluetooth adapter `0e8d:0616` is supposed to support HFP/mSBC (detected as such by pipewire), when switching to it, it fails and fall back to the low quality HFP/CVSD audio codec.

According to pipewire's dev, it could be an issue with the driver for that specific adapter since my headset (Pixel Buds Pro) works well on another machine with the exact same software stack (Ubuntu 22.10) but another bluetooth adapter where the Pixel Buds Pro works well with HFP/mSBC.

See logs attached.
