Im Original Raspbian erscheinen zunächst die folgenden Meldungen wenn journalctl -u bluealsa.service aufgerufen wird wärend man ein älteres Smartphone mit der BlueBox verbunden hat.

bluealsa: Unsupported RTP payload type: 1
bluealsa: Unsupported RTP payload type: 1

Die Bluetooth Box oder kurz BlueBox, besteht aus einem Raspberry Pi 3 oder jeden anderen Linux Computer mit Bluetooths, welcher Musik-Dateien von entfernten Geräten wie z.B. Smartphones über seine angeschlossenen Musik-Boxen wiedergibt.

sudo apt-get install autoconf libtool -y
mkdir ffmpeg
cd ffmpeg
wget -O fdk-aac.zip https://github.com/mstorsjo/fdk-aac/zipball/master

Eine neuere Version von blue-alsa wird unter Raspbian Buster kompiliert, damit auch von älteren Geräten mit pulseaudio < Version 13 Musik über der BlueBox abgespielt werden können. Wichtig ist hier beim kompilieren die Option –disable-payloadcheck.

https://github.com/Arkq/bluez-alsa

Auf dieser Webseite steht noch mal ausdrücklich warum, in meinem Fall, beim Kompilieren die Option –disable-payloadcheck verwendet wird:

disable RTP payload type check (workaround for a bug in PulseAudio versions before 13.0) Earlier releases of pulseaudio set a non-compliant value in the payload type field of RTP packets, meaning that bluetooth standard compliant devices and applications (such as bluealsa) would reject those packets. This option disables that check in bluealsa, permitting a computer running PulseAudio to use another computer running bluealsa as an audio sink. This bug in PulseAudio was fixed in release 13.0.

Nach dem Kompilieren von bluealsa wird die bestehende Binär-Datei unter /usr/bin/bluealsa mit der neuen Version überschrieben:

/usr/bin/bluealsa -V

2.1.0

Nach einem reboot sollten die folgenden Dienste für die BlueBox laufen:

Es wird eine neuere Version von Bluealsa benötigt, daher wird die bestehende mit dem payload Error durch diese ersetzt, überschrieben. Eine Deinstallation der bestehenden wurde nicht durchgeführt.

Die alte Version zeigt zunächst noch eine niedrigere Versions-Nr. an:

/usr/bin/bluealsa -V

autoreconf --install
cd build/
rm -r build/
mkdir build && cd build
../configure --enable-aac --enable-ofono --enable-debug --disable-payloadcheck
449  echo $?
apt list "*fdk*"
ls -la ../../ffmpeg_build/
history |grep PKG
export PKG_CONFIG_PATH=/home/pi/ffmpeg_build/lib/pkgconfig
../configure --enable-aac --enable-ofono --enable-debug --disable-payloadcheck
echo $?
export LIBASOUND_THREAD_SAFE=0
make
echo $?
/usr/bin/bluealsa -V
make install
echo $?
sudo make install
echo $?
/usr/bin/bluealsa -V
sudo reboot
/usr/bin/bluealsa -V
ps aux|grep -i blue
sudo journalctl -u bluealsa.service

Ist es nicht möglich sich mit der BlueBox zu verbinden?

Dann muss sichergestellt sein das der bluealsa-aplay Service läuft.

sudo systemctl status bluealsa-aplay.service

Dieser wird nicht automatisch mitgestartet wenn man den bluetooth Service startet. Es reicht aber aus nur bluealsa-aplay Service zu starten, denn dieser startet alle anderen benötigten bluetooth Services.
