Bluetooth speaker no sound. Sap driver initialization failed.

Hi, I have just installed Bunsenlabs Linux on my Sony Vaio laptop (10 year old). I have had several other distro's on linux on the laptop with no issues with bluetooth. It finds the speaker and pairs with it just fine but not sound from the BT speaker.

Any feedback appreciated.

Re: Bluetooth speaker no sound. Sap driver initialization failed.

A shot in the dark with a workaround from the RasberryPi forum:

Look for the line in
/etc/systemd/system/bluetooth.target.wants/bluetooth.service

ExecStart=/usr/lib/bluetooth/bluetoothd

and change it to

ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap

reboot

^I don't know if the problem is related to the bluez package in general, because here in siduction version 5.61-1 is installed and the line in question is:

ExecStart=/usr/libexec/bluetooth/bluetoothd

and there are no problems with bluetooth.

Does it work in the live session?
Can you connect any other bluetooth devices: mouse telephone or...

Have you configured mixer to output sound to bluetooth speaker?

Yes I have tried that workaround but it makes no difference. Thank you for the suggestion.

Re: Bluetooth speaker no sound. Sap driver initialization failed.

The live session doesn't install BT so I couldn't try it.

In Blueman the device connects to serial port OK and appears to be fine but in the mixer it doesn't show as a device.

Thank you for your feedback.

Re: Bluetooth speaker no sound. Sap driver initialization failed.

I may have fixed it. I had a look at the SerialManager plugin and configured the Script to execute connection to /dev/rfcomm0. I will reboot and see if it still works.

Just rebooted and the speaker doesn't automatically reconnect to BT but it works after connecting manually. I can work with that.
