This also works on other distros using bluealsa

Edit the file /usr/lib/systemd/system/bluealsa.service

[Unit]
Description=BlueALSA
Requires=a2dp-agent.service
After=a2dp-agent.service

[Service]
ExecStartPre=/opt/hifiberry/bin/bootmsg "Starting bluealsa"
ExecStart=/usr/bin/bluealsa -i hci0 -p a2dp-sink --a2dp-volume --pcm-buffer-time=0.1
RestartSec=5
Restart=always
TimeoutStopSec=10

[Install]
WantedBy=multi-user.target

THe only thing I have added from native is –pcm-buffer-time=0.1 If you don’t have any stutter, you could probably try to 0.05 also, adjust if you have problems.
