[pulseaudio-discuss] Current status of wideband speech?

[Ta-Lun Yen]

Diego,

Thanks for the info. Seems like I am missing something here, since it will error on entering HSP/HFP mode:

I: [bluetooth] module-bluez5-device.c: Transport /org/bluez/hci0/dev_<redacted>/fd45 resuming
D: [bluetooth] module-bluez5-device.c: Stream properly set up, we're ready to roll!
E: [bluetooth] module-bluez5-device.c: Invalid codec for encoding: 0
D: [bluetooth] module-bluez5-device.c: IO thread failed
D: [lt-pulseaudio] sink.c: bluez_sink.<redacted>.headset_head_unit: state: INIT -> IDLE

D: [lt-pulseaudio] module-device-restore.c: Could not set format on sink bluez_sink.<redacted>.headset_head_unit
