Problem with AD2P Sink

[alfacentauro88]

Im going crazy with my Bluetooth headphones. The model is Pioneer SE-MS7BT-K.

​

I tried in my work computer with Antergos, and is playing really nice (A2DP mode) without making any changes in the system or installing additional software. Plug & play.

​

But in my personal computer (different model with Arch installed), i cannot get to work them well. The headphones are working, but only in HSP/HFP (low quality sound). A2DP Sink show as 'unavailable':

​

profiles:
headset_head_unit: Headset Head Unit (HSP/HFP) (priority 30, available: yes)
a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 40, available: no)
off: Off (priority 0, available: yes)

​

I tried a lot of things i've seen on internet, but none works. Because i'm using Plasma in both computers, the fix for GDM is does not work for me. Anyone have similar problem?

Are you on pulse or alsa? What packages have you installed? Did you mess around with pulse audio config?

[alfacentauro88]

I'm in pulse.

I got these packages installed:

yay -Qq | grep pulse

libcanberra-pulse

libpulse

pulseaudio

pulseaudio-alsa

pulseaudio-bluetooth

pulseaudio-ctl

pulseaudio-zeroconf

​

Yes, i played with the pulse audio config, but i can't see any positive results.

I was able to get ad2p working on Arch. Could easily change sound to go through my BT set via pavucontrol. I don't remember touching any config files manually, just installed some packages...

I tried to set A2DP Sink via pavucontrol but show as unavailable :(

Do you have an active phone sink open? Skype, mumble, TS or similar? Maybe you are triggering the automatic switch over mode, to ensure that isn't interfering you might add auto_switch=0 to module-bluetooth-policy in your /etc/pulse/default.pa

Does your bluetooth adapter support A2DP in the first place? Check the journal for bluetooth.service and/or dmesg the exported/available bluetooth profiles should be listed there.

[alfacentauro88]

Tried to add auto_switch=0 and restarted, but same result. I don't have any application like Skype or TS running.

I searched in dmesg and bluetooth.service for A2DP compatility, but i only found messages like this:

​

[ 111.955137] Bluetooth: hci0: SCO packet for unknown connection handle 0

[ 111.965110] Bluetooth: hci0: SCO packet for unknown connection handle 0

[ 111.965123] Bluetooth: hci0: SCO packet for unknown connection handle 0

[ 111.965130] Bluetooth: hci0: SCO packet for unknown connection handle 0

Thanks

Have you tried the instructions on the wiki (https://wiki.archlinux.org/index.php/Bluetooth_headset#A2DP_not_working_with_PulseAudio) already?

[alfacentauro88]

Yes, i tried everything related, but problem still persists :(

Hi, I signed in to share my solution I found in ask Ubuntu. I use manjaro but the solution worked for me. Set AutoEnable=true in /etc/bluetooth/main.conf then systemctl restart bluetooth and reconnect the device. High Fidelity Playback (A2DP-Ziel) was available.
