RE: Bluetooth Audio output (Transmitter)
What I was doing is looking at other distro that have the BT audio working and seeing what the difference was between them.
Raspbian was the closest to our setup and the only obvious thing was pi-bluetooth. Didn't work either way. Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.

I succeed in RetroPie's kodi, But I could only get it work at the first time, after reboot, back to zero; RetroPie is based-on Raspbian, isn't that the closest distro? |

RE: Bluetooth Audio output (Transmitter)
Well I THINK I have got this working reliably. Three times in succession .
However, the quality is appalling. Stuttering and glitches, so not something you'd really use. (This might be a configuration issue or worse kernel issue.) If so, a new thread is required. These are the steps I took. Terminal sudo apt-get install pulseaudio-module-bluetooth (Thanks to @abdulmueid for the next steps) Terminal sudo gpasswd -a xbian pulse sudo gpasswd -a xbian lp sudo gpasswd -a pulse lp sudo gpasswd -a xbian audio sudo gpasswd -a pulse audio sudo reboot Terminal hcitool scan hcitool inq sudo hciconfig hci0 class 0xXXXXXX <Turn on BT scan mode> Terminal sudo bluetoothctl -a power on scan on pair xxxx trust xxxx exit Terminal killall pulseaudio Terminal sudo bluetoothctl -a connect xxxx After a little wait, something should be heard through the speaker. After a reboot, it sometimes doesn't connect automatically so rerun the connect xxxxxxx Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.

RE: Bluetooth Audio output (Transmitter)
Never seen most of those errors. The bluez.error.Failed seems to be related to permissions or not rebooting after installing.
I remember seeing something about X11 in one of the config file, but can't remember where. All mine was done on a fresh RPI2/3 install on a RPi3 and Amazon BT speaker. Have you selected Pulseaudio in Kodi and seen that it is running. Sometimes killall pulseaudio and reconnecting sometimes works.

RE: Bluetooth Audio output (Transmitter)
Are you using RPi3's onboard BT?
After disabling that crappy onboard BT and using my 12 (!!!) year old BlueFritz! BT usb stick I got it working Sound is ok and do not have any glitches, only using sound over BT and WLAN at the same time is not possible, playing video is extremely stuttering |

@Nachteule
Yes onboard!! I have a USB BT dongle, I'll give that a try and see I get the same problems. I haven't tried BT and Wifi together. If that works, I'll create a new thread for onboard BT chip problems.

RE: Bluetooth Audio output (Transmitter)
I've just done some testing on Libreelec (Couldn't get any sound output on XBian ) and the quality of the music is terrible on the RPI3 onboard BT controller, whereas using a BT dongle as the controller, the sound quality was acceptable.
So bottom line, the RPi3 BT controller should not be used for audio (Unless you have perforated eardrums or deaf). Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.

Quote:terrible on the RPI3 onboard BT controller, whereas using a BT dongle as the controller, the sound quality was acceptable. Yeah, Broadcom WLAN and BT chips are really crap. I have a Hummingboard for testing (has Broadcom WLAN and probably Broadcom BT chip onboard) and never was able to play 720p LiveTV stream over that Broadcom WLAN chip |

I can pair, trust and connect successfully, but no output to the speaker. I'll reflash and start again. (nope same problem - no sound output).

RE: Bluetooth Audio output (Transmitter)
I'll give dtparam=audio=on a try but I also tried it on a cubox-i using the onboard BT with the same result - no sound to the speaker.
BTW: Bluetooth is not enabled by default on the IMX6 image. Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.

RE: Bluetooth Audio output (Transmitter)
Is dtparam=audio=on set as default? If not, then I was running a vanilla RPi3 newly flashed image.
IMX6 /etc/default/bluetooth BLUETOOTH_ENABLED=0 Not something I have set Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.
