I've bought a Philips SHB4000 headset (phone+mic) wireless (bluetooth) and It has a good quality when I pair it with my phone or PC Windows but when I pair it with the same PC on Ubuntu (14.10 64 bits) the sound quality goes down.

I've been googling about but I haven't found any convincing answer.

Tks in advance! ....

    Sounds like you are using the HSP/HFP instead of A2DP, go into sound settings, then see what the SHB4000 is using – Jeremy31 Sep 21 '15 at 23:45
  • I had loud sound while I was changing to A2DP... I got a fright! :P Tks! Now it works with good quality! – Cleber Marques Sep 22 '15 at 0:05

Solution: Go into sound settings, then see what the SHB4000 is using. If it uses HSP/HFP change to A2DP.

    Thanks. Just noting this worked for my Sony MDR-ZX770BN as well. – Nicholas Sep 30 '16 at 0:52

    Seems I spoke too soon. When I change the settings from HSP/HFP to A2DP Sink, the sound cuts out and any applications which use sound stop working – Peeperkorn Mar 7 '17 at 15:49
  • This worked for me on Fedora 25. It temporarily re-routed things back through my desktop speakers, but I just swapped the Output Device back and forth a couple times and it started working perfectly. – Craig Otis May 11 '17 at 13:12
  • But for my Sony MDR-ZX770BN I can't change to A2DP: configuration not saved. Gubuntu 17.04 – demon101 Aug 18 '17 at 12:27

For those who had the same problem that I had (that the high fidelity playback does not work and cuts out all audio and applications that use this audio):

this script solved the issue: https://askubuntu.com/a/864841/119445

For those experiencing this with Ubuntu 16.04, and switching to A2DP only worked once, I had to disconnect, forget the device, reconnect, switch to A2DP, for it to start working again.

(Wanted to post this as a comment, but n00b-ness prevents this)

  • i added the below bluetooth config as per 56ka. didn't work this also nearly didn't work until I went back into audio and chose main speaker to be default then my current device boombar to be default again - it is a little flaky - and requires running through the sequences- – Vahid Dec 13 '18 at 15:07

Here is the solution that worked for me on Debian 9 (menu impossible to apply)

Source: https://unix.stackexchange.com/a/415928/325467


I am using a SoundBuds Curve headset in Debian 9, and have had the same problem, I was unable to switch from the HSP/HFP profile to the A2DP profile.

What fixed the issue for me, was editing /etc/bluetooth/main.conf

sudo nano /etc/bluetooth/main.conf

First add the following lines under the [General] tag (copied from audio.conf, I found searching for a solution):

# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
AutoConnect=true

Next you must enable support for multiple profiles (a few lines below) just uncomment and set value to multiple

MultiProfile = multiple

Then restart bluetooth service

sudo systemctl restart bluetooth 
0

I had to do both setting the main.conf to multiple profiles then remove the headphones and add them back and then they defaulted to High Fidelity.
