I'm trying to pair my Skullcandy Crusher Wireless headphones to my computer. I'm able to get them paired, and selected in the sound menu successfully, but for some reason audio still plays through the internal speakers?

I tried the fixes described in 477933, and https://www.nielsvandermolen.com/bluetooth-headphones-ubuntu/ to no avail

This is what my settings menu looks like: settings img Which is wierd because it looks like both the output and the input are hooked together, but I never set them that way?

Does anybody know how to fix this?

Edit

Here are the printouts from the dmesg commands in the tutorial from above

When I went into the alsamixer it showed my headphones were, muted, so I unmuted them, as the SO question above indicated, but that didn't help things either.

Update

Okay, I'm working through the Sound Troublshooting Guide and have found a couple things to note.

  1. When I execute
pacmd
>>> list-sinks
>>> exit

It lists the bluetooth headphones as a sink, but upon exiting, my bluetooth system crashes, and I have to reboot my headphones to get them to reconnect. Here is the output from the command:

Note that the headphones are not muted, and the output volume is at 100%

  1. When I execute aplay /usr/share/sounds/alsa/Front_Center.wav THE SOUND COMES OUT OF THE HEADPHONES! But if I go back to the settings menu and try to test the speakers, or if I play music through Firefox, the sound comes out of the internal speakers, still.

  2. The rest of the steps came out normal, except I noted that when I use aplay -l my list doesn't include the headphones as an audio sink, which might be important? I don't know.

Here is the outputs from the corresponding commands for the guide:

    Output going to the wrong device is pretty odd, no idea what's happening there. The input device is likely a bluetooth microphone on the headset. Have you already looked over the (extremely outdated) resources at help.ubuntu.com/community/SoundTroubleshooting? – Christian Aug 19 '20 at 17:36

    option # 3 here might help or rule out issues related to pulseaudio configuration. – Raffa Sep 3 '20 at 13:06

I would first suggest rebuilding new pulseaudio configuration for your user account. This might, in many cases, fix the problem or at least rule out issues related to pulseaudio configuration.

Old pulseaudio configuration files can sometimes conflict with newer versions of pulseaudio after package upgrades. To fix this please follow the steps below:

  • Back up ~/.config/pulse/ configuration directory to ~/.config/pulse_old/ by running the following command in the terminal:

    mv ~/.config/pulse/ ~/.config/pulse_old/

  • After that, please reboot your system to build new pulseaudio configuration files. A new ~/.config/pulse/ directory will be created automatically.

  • Test your audio now.

If, somehow, after applying this fix you decide to go back to the previous state before applying the fix, please follow the steps below:

  1. Run the following command in the terminal:

    rm -r ~/.config/pulse/

  2. Run the following command in the terminal:

    mv ~/.config/pulse_old/ ~/.config/pulse/

  3. Reboot your system.

However, if all is okay and the problem is fixed, you can remove the backed up old configuration directory ~/.config/pulse_old/ to free space ( if you wish ) by running the following command in the terminal:

rm -r  ~/.config/pulse_old/

I had a similar problem once, both in Windows and Linux, and the solution in both systems was to disable the headset microphone (choose internal microphone).

It seems (discussion here) that the bluetooth interface supports only one of these

  • High quality (a2dp) audio output, OR
  • High quality (a2dp) microphone input, OR
  • Low quality (hsp/hfp) input and output.

It might be the case that your headset microphone is capturing with high quality, thus it blocks your headset speakers.

  • I tried that, but it doesn't work – iggy12345 Aug 25 '20 at 17:56
  • This answer is also correct, though, it was not the original issue I was having. But it is also important to note – iggy12345 Sep 3 '20 at 15:07
