Good Evening everyone, Today I tried to configure my audio bluetooth device after the PC pairing and device, finding a problem with the audio that transmits the PC. Some time ago I had Windows 10 pre-installed in the PC and I had no such problem. The device is designed to also support Linux Ubuntu. The problem that I see is that my computer transmits in mono instead of stereo mode. I also went into the Gnome settings but not change anything even if I change the profile A2DP Sink mode as I had read in various forums. I would like to know if you can do something to remedy this problem?
I've had the same problem since Ubuntu Gnome 15.04. I have a photive speaker that supports both A2DP and headset modes. It works with my android phone, with the same computer in Windows 10, and with another computer running Fedora 23. I believe it also worked with Linux Mint on the same hardware. But it's never worked with Ubuntu Gnome; it connects as a headset, and the A2DP protocol is disabled.
Edit: I just tried the instructions here, and they worked for me; my speaker is currently connected in A2DP and playing in high-quality stereo. However, I have tried them before, and they did not work on previous Ubuntu versions, so your mileage may vary.
This is still less than ideal, because now I will not be able to switch to headset mode to use the microphone.
Edit 2: I spoke too soon. I just rebooted the machine to see if the changes would stick, and they did not - the headset would not even connect. I started working through a few of the steps that I've found: I reloaded pulsaudio's bluetooth-discover module, and that didn't work; I then restarted the bluetooth service, and now it works. So, try this, and see if you get the same results.
pactl unload-module module-bluetooth-discover pactl load-module module-bluetooth-discover sudo systemctl restart bluetooth
I'm not sure which of these steps is actually solving the problem. Also, note that I did not kill and restart pulse itself, since that seems to confuse already-running applications.
