Pactl set-card-profile $BLUEZCARD headset_head_unit Pactl set-card-profile $BLUEZCARD a2dp_sink For instance, this is what my file looked like for my LG Tones.
Lag vs dsync code#
touch bluezswitch.shĬopy and paste the code at the very top of this comment and replace the a2dp and hsp with the values you got when you ran the above command, and paste it in that file. I called the file bluezswitch.sh.Ĭhange to the directory you want to put the file. Now, with the above code, we will modify it and put it into a file. Notice this is different than the original poster's a2dp and hsp. In this case, they are a2dp_sink for the a2dp profile, and headsethead_unit for the hsp profile.
The two profiles we need should have in them (A2DP Sink) and (HSP/HFP). In this section, we see three profiles, which are a2dp_sink, headset_head_unit, and off. We are interested in the profiles section. Headset-input: Headset (priority: 0, latency offset: 0 usec) Part of profile(s): a2dp_sink, headset_head_unit Headset-output: Headset (priority: 0, latency offset: 0 usec) Off: Off (sinks: 0, sources: 0, priority: 0, available: yes)
Headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 20, available: yes) For instance, with the LG Tone Ultra headset, I get this: Name: bluez_card.B8_AD_3E_**_**_**īluez.path = "/org/bluez/hci0/dev_B8_AD_3E_**_**_**"ĭevice.icon_name = "audio-headset-bluetooth"Ī2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 10, available: yes)
Lag vs dsync Bluetooth#
This will return everything after where it finds a bluetooth device. That code will work for most bluetooth devices it appears, but to get this working correctly for those devices that don't have the a2dp profile or the hsp profile, type in: pactl list | grep -Pzo '.*bluez_card(.*\n)*' #!/bin/bashīLUEZCARD=$(pactl list cards short | egrep -o bluez.*]) Neither of these are available with my LG Tones, for example, but they are with other devices like my Sony headset. For instance, in the following code, which was originally posted by that person, it apparently has profiles named a2dp and hsp. Some devices have different profile names than what that poster has with his Bluetooth speakers. The top reply here works, but not for every Bluetooth audio device. Whenever you connect and notice the lag, you should press the keyboard shortcut chosen above to attempt to fix the latency - hopefully it works for you! What this does is force the PulseAudio system to resynchronize the audio being sent to your headset/speakers by switching profiles from ad2p -> hsp -> a2dp, thus hopefully getting rid of any latency. Click Apply, and then click on the right where it says Disabled to set up a keyboard shortcut to execute the script. Go to, and create a custom shortcut name it whatever you want, with the command as /home/$USER/pabluezswitch.sh (substitute with the appropriate path). Make the file executable by opening a terminal and typing chmod +x ~/pabluezswitch.sh sh file in your home directory, say /home/brillout/pabluezswitch.sh: #!/bin/bashīluezcard=$(pactl list cards short | awk '/bluez/')
Try this:įirst, delete and re-pair your Bluetooth device. If you're looking for a culprit, I'd look at Ubuntu's sound system, PulseAudio first, and then your Bluetooth receiver. Auto-switching Bluetooth profiles to re-initialize PulseAudio
Something similar in concept to Sri's answer almost always works for me, and I need to do it only once per connect. No, this is not normal but I've had a similar problem occasionally with my Altec Lansing iMT525 Bluetooth Speakers.
