Bluetooth speakers work only in mono audio mode
Closed, ResolvedPublic


Hi guys,

My Sony MDR-XB80BS bluetooth headphones get paired/detected but only work under a 'Headset Head Unit (HSP/HFP)' profile. Which means I only get a 'mono' audio mode, unlike nice stereo audio quality I used to get until (about) a month ago or so, when I could select 'AD2P' and audio quality was great.

Already asked about it on the forums:

@sunnyflunk was really helpful and helped me cover the basics, but sadly issue is still there.

Any info about my system that I can provide to you that could help please let me know.

In case it's useful, this is my inxi -F output:

Wasn't aware of the lsusb command used by @swoop. In case it's useful, here's also my output:

lsusb | grep Bluetooth
Bus 001 Device 009: ID 413c:8160 Dell Computer Corp. Wireless 365 Bluetooth
Bus 001 Device 003: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

Hope it helps.

Bluetooth headphones DGTEC also only receiving mono sound on Asus tablet EP121, was previously able to select High Fidelity AD2P - (Sound Settings) - (Output Tab) - Profile: Headset Head Unit (HSP/HFP) is all that's available for selection.

I can confirm my Bluetooth is working beautifully after last (yesterday's) set of updates. Yay..!

Thanks for all your work :)

P.S.: If I'm the one supposed to close this issue (given I was the author in the first place) please let me know (since I dont' see an option I assume I lack privileges or something). Cheers!
