I'm having issues using my Sony WH-1000MX3 Bluetooth headset with my beloved Ubuntu 18.04. Ubuntu does not seem to be able to use the headset as a handsfree (which would be useful with all the video-calls going on). The problem is partially solved, as I'm able to use the headset for audio output, by changing the Bluetooth profile to A2DP using blueman. However, I still haven't found a solution for using the headset for audio input (which I believe would require HSP/HFP profile?).

Originally I thought the Bluetooth of the laptop might be incompatible, however, with my dual-boot Windows the headset works without issues. So I believe the issue should not be on the hardware?

More so, the Ubuntu settings and Pulseaudio seem to recognize the headset as an audio input - however, no audio is received from the headset.

While looking into the problem, I found out the following lines from cat /var/log/syslog:

Apr 23 09:46:31 mande-Lenovo-Y50-70 /usr/lib/gdm3/gdm-x-session[2754]: (II) event19 - CC:98:8B:80:DC:C3: is tagged by udev as: Keyboard
Apr 23 09:46:31 mande-Lenovo-Y50-70 /usr/lib/gdm3/gdm-x-session[2754]: (II) event19 - CC:98:8B:80:DC:C3: device is a keyboard

Where the Mac address of CC:98:8B:80:DC:C3 corresponds to the headset.

My friend suggested looking into udev output, but we could not find anything suspicious. Here's the udevadm output for headset connecting:

mande@mande-Lenovo-Y50-70:~$ udevadm monitor -e
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

This is where we ran out of ideas on how to proceed. Any pointers on where what to look into would be highly valued. Thanks in advance :)


Update 18.5:

I tried connecting another headset Bose QC35 II, but again I'm only able to use the headset as audio sink (A2DP sink). When trying to connect the headset as input device, the headset says: "a call from" and gives static noise after that.

Again from cat /var/log/syslog it seems that the headset is recognized as keyboard:

You are right about HSP/HFP being required for audio input. Bluetooth can be quite finicky, make sure to try forgetting the headset and repairing it.

For helping with troubleshooting, here is the output of /usr/bin/pacmd list-sources for my blueheadset in HSP/HSF mode.

I do see that I have suspend cause: (none) and you have suspend cause: but that is the only difference I can notice.

FYI, when working with bluetooth sometime restarting the bluetooth service alone isn't enough. I found this works better: sudo rfkill block bluetooth && sleep 0.1 && sudo rfkill unblock bluetooth;

  • Indeed the "suspend cause" appears to be the only real difference for the headset entry. Unfortunately, the restart of the Bluetooth service does not work in my case - the voice-input does not seem to get registered at the laptop (Sound setting show 0 on the input level). – Manezki May 11 '20 at 8:39
  • You could try removing and reinstalling the blueman package. Also try hooking up some other Bluetooth device and see if the mic works on that. – Chart96 May 12 '20 at 12:10
