I've discovered again that cursing and swearing at inanimate objects doesn't actually improve things, so I'll try posting a question.
A couple of months ago I attempted a fairly ambitious project (Sonos Bluetooth Bridge) with my RPi that didn't work out. It was a fairly complex project IMHO, and as the author of the article didn't respond to help requests, I decided to set it aside, and start with a simpler Bluetooth project.
Connecting to a Bluetooth speaker seemed straightforward enough, but I'm now wondering if there is such a thing as a simple Bluetooth project. My setup is simple:
- Raspberry Pi 3B+ w/ current Raspbian stretch
- Anker SoundCore mini speaker
Just to verify the speaker worked, in about 2 minutes I was able to connected from my phone & play music. Speaker works.
Here's an attempt to show the relevant software on my system:
$ dpkg -l | grep blue ii bluez 5.43-2+rpt2+deb9u2 armhf Bluetooth tools and daemons ii bluez-firmware 1.2-3+rpt7 all Firmware for Bluetooth devices ii pi-bluetooth 0.1.10 all Raspberry Pi 3 bluetooth ii pulseaudio-module-bluetooth 10.0-1+deb9u1 armhf Bluetooth module for PulseAudio sound server From my RPi, I used bluetoothctl to discover and pair with the speaker as follows (some steps deleted for brevity):

This answer refers to another answer on the SE Ubuntu site.. And one other answer on Unix&Linux SE.
I think I've followed the steps correctly. I've edited both files IAW the referenced answer, rebooted, used pactl, but I still get the failure:
Failed to connect: org.bluez.Error.Failed
FWIW, the pactl step succeeds once per reboot, trying to load-module again gets an error, but it can be unload-ed, and then load-ed successfully:
$ pactl load-module module-bluetooth-discover 20 $ pactl load-module module-bluetooth-discover Failure: Module initialization failed $ pactl unload-module module-bluetooth-discover $ pactl load-module module-bluetooth-discover 22 $ The syslog shows the following for each attempt at a connection w/ bluetoothctl:
bluetoothd[491]: a2dp-sink profile connect failed for F4:4E:FD:2A:3C:B6: Protocol not available Any ideas or suggestions are much appreciated.
