[SOLVED] Bluetooth headphones connected but no sound

[misket]

Hello everyone,

I have a pair of earbuds that used to work flawlessly, but recently they stopped working, I don't know why and when. I still can connect them via blueman, and can see and select them in pulseaudio menu's default sink section, but there is no sound.
When I play a music or start a video, it immediately gives some kind of a background noise, when i stop or pause the media, this sound stops too.
It is strange, I used to use them without any problem. I don't know if this is happened after I made a few updates.

They are selected as A2DP, I tried re-pairing the device, reinstalling pulseaudio/pavucontrol, nothing happened. I tried running the script here: https://gist.github.com/pylover/d68be36 ... 5e6ed6e7ae

Here is the output:

Have you checked https://wiki.debian.org/BluetoothUser/a2dp

I think Debian Wiki is the best place to start with Debian specific problems.

I think Debian Wiki is the best place to start with Debian specific problems.

Yes I did check this page. There are four possible issues in the troubleshooting section:

• - Refused to switch profile to a2dp_sink: Not connected
  - Unable to control volume with volumeicon-alsa
  - a2dp-sink profile connect failed [...]: Protocol not available
  - aptX (HD) and LDAC codecs are not available to be used with my device

and I think none of them provides a solution to my problem.

Here is something I just discovered: When I connect another bluetooth headphone (Jabra), it works. Also another thing, right after I connect to my IP010-X Pro's, when I play a media, I think I barely hear something for a second. Then again, only this background noise, like if it is muted.

I can select the device as audio sink. There is a section for device in pavucontrol Output Devices section. Everything seems to be working fine, but no sound!

As I said, since last week I was using these headphones without any problem on Debian, and I still can use them with my mobile phone. I really don't know what the problem is.

May give some hints. Search engines are your friend.

I got mine bluetooth headphones working following Debian wiki, so I have no first hand experience of trouble shooting.

Generally command line is preferred in those situations, as it gives error messages, like in the link above.

EDIT: Do you really need that github script?

Thanks for the advice.
Actually, posting to a Linux forum is not the first thing I do when I come across with a problem. I do usually check wiki pages, then forum posts concerning similar problems, in fact, that is how I found this github script.
Anyway, I don't really know how, but my problem seems solved right now. Although I tried re-pairing for a couple of times from blueman GUI, this time I re-paired them from terminal and now they are working without any problem.

Great you found the solution!

Could you please edit the header of your first post in the thread and add [SOLVED] to it.
