I'm using Dell latitude 5480 with dual boot, Windows 10 and Ubuntu 20.04 LTS. My Sony C200 wireless earphones works pretty decent with Windows 10, but on Ubuntu I've searched through all topics which were:

  1. changing HSP/HFP to A2DP.

  2. adding following text to sudo nano /etc/bluetooth/main.conf

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 and setting: MultiProfile = multiple

Bluetooth headset with poor sound quality on Ubuntu

none of were working for better and decent sound quality. if it is possible anyone help me with my problem.

sudo nano /lib/systemd/system/bluetooth.service

Change

ExecStart=/usr/lib/bluetooth/bluetoothd

to

ExecStart=/usr/lib/bluetooth/bluetoothd --plugin=a2dp

sudo systemctl daemon-reload

  • This worked for me on Xubuntu 22.04. No new packages needed to be loaded, but a reboot did appear necessary: system locked up hard when pavucontrol tried to access the pulseaudio daemon. – Mei Jun 24 '23 at 17:09
  • Also, when you do this, make sure to select A2DP in pavucontrol, as that is the default used. In my case at least, it doesn't default to A2DP... probably a setting I'm missing. – Mei Jun 25 '23 at 19:41

Find out the bit depth of the equipment: sudo lshw -C sound

Try it here... gedit /etc/pulse/daemon.conf

##; resample-method = speex-float-1
; resample-method = src-sinc-best-quality

; flat-volumes = yes


##; default-sample-format = s16le
##; default-sample-format = s32le
##; default-sample-format = s64le
##; default-sample-format = float16le
##; default-sample-format = float32le
; default-sample-format = float64le
##; default-sample-rate = 44100
##; default-sample-rate = 48000
; default-sample-rate = 88200
##; alternate-sample-rate = 48000
; alternate-sample-rate = 96000
; default-sample-channels = 2
; default-channel-map = front-left,front-right

I have a better sound than in Windows, everywhere, on Bluetooth speakers and headphones.
