Troubleshooting Bluetooth

#1 Post by d3viant »

Debian/Gnome came with a Bluetooth GUI. On first attempt to connect my device, Debian found it but I could not switch the connection for the deivce 'on'

So I followed this:
https://wiki.debian.org/BluetoothUser/a2dp

(I did not install Blueman)
Reboot, no luck.

I did not follow the modification to /var/lib/gdm3/.config/pulse/client.conf -- because I am now wondering if this is a kernal bug? I had an identical issue in Ubuntu, but only after the latest update (Bluetooth worked fine on it before)

Is anyone else experiencing issues with Bluetooth?

Is it safe to apt-remove these packages, or should I leave them?
lsb_release -da

Maybe gdm is at fault. Did you try editing /var/lib/gdm3/.config/pulse/client.conf as stated in the wiki that you linked?

I ended up upgrading to 9 as I was having issues with wifi and whatnot.

Now, Bluetooth pairs / works without issue.. but once my PC reboots, the sound profile reverts to major garbage; its flat sounding!

in /var/log/syslog (not sure if this is related?):

Code: Select all

Last night, I added this to /etc/pulse/daemon.conf and the sound was perfect:

Code: Select all

resample-method = src-sinc-best-quality
default-sample-format = float32ne
alternate-sample-rate = 96000
then:

Code: Select all

pulseaudio --kill
service bluetooth force-reload
Went into sound manager, set the profile for the Bluetooth speaker as Hi-Fidelity Playback (A2DP Sink) -- which worked last night, but today, it refuses to take that profile and when it *does* accept it, the music automatically stops on the Bluetooth speaker and starts on my internal laptop speakers (which are even worse sounding because of how tiny they are).

Assuming I fudged the config somewhere, can anyone spot my mistake?
