Linux NOT Mint Bluetooth Problem

[bartszu]

Yo Boys and Girls

Recently I run into stunning issue
Got Bluetooth v. 5.0 dongle for my PC.
Dongle runs, responds, linux has no probs to find or list it all abilities, no driver issues.
Driver acts on all commands, as is present in kernel.

As my experience with Bluetooth was so seamless on other Linux called Android.

I was shocked HSP/HFP mode is not present ;(
And A2DP mode runs as charm.

Quickly fond that problem is ancient regime called PulseAudio.

So I did:

Code: Select all

sudo apt install pipewire
sudo apt install libspa-0.2-bluetooth
sudo apt install pipewire-audio-client-libraries
systemctl --user daemon-reload
systemctl --user --now disable pulseaudio.service pulseaudio.socket
systemctl --user mask pulseaudio
systemctl --user --now enable pipewire-media-session.service

Another set of no problems, all run with no problems.

Code: Select all

pactl info

Outputs: PulseAudio (on PipeWire 0.3.28)

Code: Select all

alsamixer

Runs on PipeWire

Yet HSP/HFP still not runs, although system allows to switch to it.
No sound tho ;(
I mean no sound in HSP/HFP, as rest is Sound

Do I still have PulseAudio running somewhere ?
Kill it ?

a I run kernel 4.0 and Mint 19

How is your Bluetooth input/duplex on kernel 5,0 ?

any problems ?

The supported kernels for Mint 19 versions are 4.15 and 5.4. If you are running kernel 4.0, then I suggest you switch to an updated kernel.

If you are running Mint 19 Tara, use the latest 4.15 kernel.

[bartszu]

That is the kernel I am running.

4.15 is a newer kernel than 4.0 which is why I asked.

I found this askUbuntu question Can't use bluetooth headset in HSP/HFP mode - ubuntu 20.04 which is specifically about Mint 20's base version, but maybe something in there will help you.

You can always take a Timeshift snapshot before making any changes so if the changes do not work on your version then you can roll back.

yeah this is kinda helpfull

Still kinda sad, to read those.
Internet is full of complains and descriptions of issues.

Way the heck handling Bluetooth on Linux require still so much development to come ??
Way this is laging so much after properitary distros like Android ??
BT is an open standard, open I mean, there is no secret how it works or black box, like it was in nVidia case.

On Android this all acts plug and play, you dont even know, some app has changed you a BT mode.

This link mentions installing a bluetooth module for pulseaudio and that it helped.

I do not know if it might work better on a version with a newer kernel. The Linux Mint 20.2 "Uma" - Cinnamon (Edge, 64-bit) ISO has the 5.11 kernel if you want to try a live session with it to see if a newer kernel helps the situation.

"Nevertheless, it is difficult to find a Linux-compatible Bluetooth dongle because there aren’t many companies that support Linux. Considering how difficult this task is, we have composed a list of the 5 best USB Bluetooth adapters compatible with Linux

A few years back I had to buy a Bluetooth dongle and I did a lot of research before buying one, as not all support Linux. I ended up buying a Cirago blue-tooth from Amazon because it plainly stated it support Linux. I plugged it in and it worked on more than one Linux OS and more than one brand of computer. Do some research before buying a Bluetooth dongle to save yourself a lot of headaches.

Operating Systems Supported Windows 7, Vista, XP, 2000, Mac OS 10.4.7 or above, Linux

WHy is GNU/Linux behind proprietary distros like Android in hardware support? Simply a lack of resources. They don't just give away those SDK, they charge significant $$$ to just look at them.

WHat will often happen in Linux with such things is that the gear mfr uses the open standard and then adds proprietary doodads to the product. So the doodad may now work in Linux at all or certain features won't.
