Couldn't initialize controller thread: Address already in use #73

Closed SuperSam56 closed 6 years ago

SuperSam56 commented 6 years ago

Hi @Arkq, I just installed a fresh new install of Raspbian Stretch, on which i would like to stream Audio from my Android Phone via Bluetooth A2DP. By the way on https://www.raspberrypi.org/blog/raspbian-stretch/ paragraph "Bluetooth audio": they say "...For Stretch, we are using the bluez-alsa package to make Bluetooth audio work with ALSA itself" So i though there is nothing more to do after having paired my bluetooth android phone with my raspberry pi (which seems to be done succesfully) Unfortunately when i launch the bluealsa command i have only a error message return "Couldn't initialize controller thread: Address already in use" And when I try to restart bluealsa after pkill bluealsa, it never launches. Could you please help me understand and resolve this issue ? thanks

When installed on Raspbian Stretch bluez-alsa automatically runs on boot via systemd. Manually executing the bluealsa command is not necessary.

If the Android device recognizes the Raspberry Pi as an audio device when pairing then bluez-alsa is running correctly.

To play audio from the phone, on the Raspberry Pi you should use the bluealsa-aplay command as documented.

Indeed @mill1000 and @Arkq this is working with either bluealsa-aplay or arecord -D bluealsa:HCI=hci0,DEV=XX:XX:XX:XX:XX:XX,PROFILE=a2dp commands (XX:XX:XX:XX:XX:XX is my bluetooth android phone address). But this works only when i disable Wifi, otherwise i have sound jumps / jitters effects (same as issue#60 ?). So is there a reason for this particular behavior of sound streaming when Wifi is on? Is there a fix for this? Furthermore i have a final question: I want to use darkice package to catch a2dp bluetooth sound in a .mp3" mounted file. How should i configure darkice.cfg in its [input] section.

Because when i set the following parameter in darkice.cfg file: device = bluealsa:HCI=hci0,DEV=AD:EF:9E:3B:54:EA,profile=a2dp

and when i launch Darkice, i get the following error message:

Many thanks for your help

Is this on a Pi3? There is a known issue when operating the on-board WiFi and Bluetooth together.

I opt'd for a cheap USB Bluetooth dongle to resolve the problem.

SuperSam56 commented 6 years ago

Yes this is a Pi3B. Do you know if this known issue is also affecting the Pi Zero W which is also both bluetooth and Wifi ? And could you also please give me some indications on where i could find help to configure darkice to work with bluealsa a2dp ? Because i only find tutorial to make it work with pulseaudio. many thanks
