Just bought and setup up Raspberry Pi Sunday. The version is Raspbian Stretch.
All is working except bluetooth. I have been able to get a bluetooth device, Bose Color Soundlink, to pair with Rasp Pi, but no sound.
The bluetooth icon > Remove Device, says Bose Color SoundLink is paired, and is available to remove.
In the bluetooth dropdown icon, when I click on Connect net to the Bose Color Soundlink , I receive the error
"Connection failed - Use the audio menu to connect to this device"
So where is the "audio menu"? is it Preferences > Audio Device Settings?
If so, the sound card is bcm2835 ALSA (Alsa mixer) (Default)
no controls visible
When I try to pair the speaker, I get the message
"Paired successfully. Use the audio menu to select as output device"
Back in audio device settings, everything looks the same. I made PCM the default control, that's the only one available, ` but nothing changed - no sound.
Plugged headphones into jack in Rasp Pi, no sound. Made PCM the default in Audio Device Settings -- still no sound.
I cannot find anything that is muted.
