Dell G3 - Bluetooth audio delay and mic not working

Support Sound
1

Hello,

I’ve made a clean install of Manjaro GNOME on a Dell G3-3590-A20P.

Initially, there was no sound support at all (Dummy output and no mic), also jack wouldn’t work either.

Browsing the web and Arch Linux forums, I’ve found that modprobe options snd_hda_intel dmic_detect=0 would enable internal speaker and jack input/output at the cost of disabling internal mic.

Now I’ve done more research and updated to Kernel 5.9, removed the hackish modprobe, and installed sof-firmware. After tinkering a bit with alsamixer volume levels, I’ve got the internal speaker/mic and jack input/output working as expected.

The remaining problem is that my bluetooth headphones (JBL Live 300TWS) have about 1s output delay and I can’t get the mic (audio input) to work.

Looking at journalctl -b -p err, I see this error after connecting to bluetooth headphones at startup:

Nov 11 11:48:38 ult-g33590 bluetoothd[462]: src/profile.c:ext_start_servers() RFCOMM server failed for Headset Voice gateway: rfcomm_bind: Address already in use (98)
Nov 11 11:48:38 ult-g33590 bluetoothd[462]: src/profile.c:ext_start_servers() RFCOMM server failed for Headset unit: rfcomm_bind: Address already in use (98)

And I see this error after disconnecting and connecting the bluetooth headphones again:

Nov 11 11:50:21 ult-g33590 bluetoothd[462]: src/service.c:btd_service_connect() a2dp-source profile connect failed for B4:9A:95:EE:66:10: Device or resource busy

From the “address already in use” error, I would assume I have to stop a service or kill the process that is already using the address/port, but I’ve had no luck debugging this so far.

Here’s my system info:

Just to recap, I would like to get the bluetooth mic working and fix the output delay if possible.

I have virtually no experience with Linux firmware, let me know if there’s any other useful info I can post. Any pointers are appreciated.

Forgot to mention, the bluetooth headphones show up in Settings -> Sound -> Output and it works (although with a significant delay) but they do not show in inputs.

I’ve tried everything I could find from Arch Linux forums.

Installing bluez-utils does not fix the issue. Using rfkill to block and unblock bluetooth, as well as restarting the bluetooth service does not change anything.

I don’t know if this is the appropriate forum, please move to Networking if it makes sense.

Connect the headphones, then run pactl list cards, and post the output.

By the way, I also tried to upgrade pulseaudio to devel version (yay -S pulseaudio-git) and it completely broke audio support after restart (not even dummy output).
Then I tried to revert it but I ended up breaking some dependencies and bricked my GNOME. I booted through runlevel 3 and just got everything up running again.
So it seems upgrading to pulseaudio-git does not fix the issue, or maybe I missed something in the process.

The necessary profiles/ports don’t seem to be available for some reason.

Thanks, I’ve noticed the unavailable profiles could be an issue.

I’m looking at the Arch Linux Wiki’s Bluetooth headset > “A2DP sink profile is unavailable”, tried all solutions to no avail.

After replacing pulseaudio-bluetooth with pulseaudio-modules-bt-git, source profiles are still not available:

Unfortunately, I cannot help you more, as a last resort, you can try opening an issue on the freedesktop gitlab.

No problem, thanks for the help so far, @pobrn.

I’ve seen several threads around the web about this kind of problem, and it always seems to end without answer.

I have another laptop with Manjaro Linux where I believe these phones work properly, so I guess I’ll try to compare all installed packages, firmware modules and codecs to see if I can find any other leads.
