## When BlueALSA has been created, then you can start BlueALSA as background task:
#bluealsa --disable-hfp &

# Now - for using your bluetooth-speaker/headset - with BlueALSA you have to intoduce the device to the bluetooth-stack using bluetoothctl:
# bluetoothctl >
# scan on
# [NEW] Device 30:23:23:F4:48:2C TH-S10U
# scan off
# pair 30:23:23:F4:48:2C
# trust 30:23:23:F4:48:2C
# exit

# After that power off&on the bt-speaker device and the device will connect automatically as a trusted device.

# Before we try our first audio-command we had to export one thing to make BlueALSA mor system-friendly:
export LIBASOUND_THREAD_SAFE=0

# autostart bluealsa
#cat <<EOF > /etc/rc.local
## Start bluealsa as root <https://github.com/Arkq/bluez-alsa>
#export LIBASOUND_THREAD_SAFE=0
#/usr/bin/bluealsa -S &
#EOF

# Text to speech:

# espeak "Hello, how are you?" -w /home/guido/espeak.wav -s145
# aplay -D bluealsa:HCI=hci0,DEV=30:23:23:F4:48:2C,PROFILE=a2dp /home/guido/espeak.wav

# Internetradio:

# mpg123 -a bluealsa:HCI=hci0,DEV=30:23:23:F4:48:2C,PROFILE=a2dp -@ /home/guido/ffh80s.pls

# For shorting the command you could create a ~/.asoundrc with the following content:

# defaults.bluealsa.interface "hci0"
# defaults.bluealsa.device "30:23:23:F4:48:2C"
# defaults.bluealsa.profile "a2dp"
# defaults.bluealsa.delay 10000

# Now you can the shorter version of the command:

# mpg123 -a bluealsa -@ /home/guido/ffh80s.pls

# For set the volume of such a device you have to know the "real" name of the device out of the bluetoothctl and the name of the used protocol:

# Device: 30:23:23:F4:48:2C TH-S10U
# Protocol: A2DP
# amixer -D bluealsa sset 'TH-S10U - A2DP ' 70%
