Ubuntu 20.04 as Bluetooth Speaker (A2DP sink) - volume control broken

us flag

I have been able to pair my iPhone SE (iOS 14.4.2) with my Ubuntu Desktop (20.04) using the default bluetooth settings application and I can play music and this is great but controlling the volume from iOS is not working. When I bring the volume all the way down to silent/mute the Ubuntu Desktop does mute its output but all volume levels above zero result with 100% volume.

I solved my issue using modifications to the SystemD Bluetooth service proposed by this answer on a related question. Specific to Ubuntu 20.04 the SystemD service file has a different path.

Open this file as root: /etc/systemd/system/bluetooth.target.wants/bluetooth.service

Change this line: ExecStart=/usr/lib/bluetooth/bluetoothd

To this: ExecStart=/usr/lib/bluetooth/bluetoothd --plugin=a2dp

Then run these two commands:

sudo systemctl daemon-reload  
sudo systemctl restart bluetooth
mangohost

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
