Poor quality sound with bluetooth headset

Hello,

I have a Lindy BNX-60 bluetooth headphone.
I usually use it with my phone and it works great.
However, if I connect it via bluetooth to my laptop running arch, the sounds is terrible. It is not as clear, a bit muffled. I have to put the volume higher but the voices are not as understandable when I am connected to my phone or when I use a jack.

Any idea ? Does it depends of bluetooth driver or something ?

Re: Poor quality sound with bluetooth headset

Are you using the A2DP profile? What are the outputs of

pacmd list-cards
pacmd list-sinks

aptX which is apparently the most modern Bluetooth protocol, is proprietary and doesn't have a free implementation available afaik.

It seems indeed that it uses aptX :-/

How can I check for A2DP?

Re: Poor quality sound with bluetooth headset

That's what I wanted to find out, but apparently you didn't have the bluethooth headset connected when executing these commands, or did you?

Re: Poor quality sound with bluetooth headset

oh my bad, it dropped indeed (getting issues to connect it from time to time).
I have updated the previous post

Re: Poor quality sound with bluetooth headset

try

pacmd set-card-profile 2 a2dp_sink

Also, looks like you use Gnome and probably GDM, take a look here:

Re: Poor quality sound with bluetooth headset

Great, sounds better indeed.
Yes I use GDM, I will try your link to see if it is enabled at startup

Thank you. You solved my problem.


Get the index of your card:

pacmd list-cards

Set the cards profile to a2dp (example: index 2):

pacmd set-card-profile 2 a2dp_sink

Hello,

I have similar problem with my bluetooth speaker. When it is connected via cable sound is good, but on bluetooth it is awefull.
I'm on Manjaro 19.0.2, GNOME 3.34.4. I tried this (pacmd set-card-profile 1 headset_head_unit) but it did not work and followed guide from wiki for GNOME, but it did not help.
