I have my NAS on the base of Cubietruck (Ubuntu Xenial with Armbian Linux 3.4.113-sun7i) with integrated bluetooth. Now I'm trying to send audio to my bluetooth speaker via bluealsa.
Initially I've used this manual to install and setup bluealsa: https://forum.armbian.com/topic/6480-bluealsa-bluetooth-audio-using-alsa-not-pulseaudio/
I've ended with same problem as I'm having now after recompiling and setting up bluealsa again using this manual: https://raspberrypi.stackexchange.com/questions/90267/how-to-stream-sound-to-a-bluetooth-device-from-a-raspberry-pi-zero
which gave me a bit more progress, for example I can see such message while connecting to my bluetooth speaker: [BH129]# bluealsa: D: ../../src/bluez.c:1267: Signal: org.freedesktop.DBus.Objec tManager.InterfacesAdded()
I didn't see such message when installed and setup bluealsa according to 1st manual.
I'm starting bluealsa first manually after boot. By the way is bluetooth-profile correct: - hsp-hs Headset (v1.2)?
bluealsa -p hsp-hs &
Bluealsa seems to be running:
root@Artisan:~# ps -ef | grep bluealsa
root 2591 2557 0 15:16 pts/0 00:00:00 bluealsa -p hsp-hs
root 2803 2557 1 15:58 pts/0 00:00:00 grep --color=auto bluealsa
Here's how I connect to my speaker:

I was a bit confused with "Alsa config" section and ended with configuring it this way:
root@Artisan:~# cat /usr/share/alsa/alsa.conf.d/20-bluealsa.conf # BlueALSA integration setup
defaults.bluealsa.service "org.bluealsa"
defaults.bluealsa.profile "a2dp"
defaults.bluealsa.delay 20000
defaults.bluealsa.battery "yes"
ctl.bluealsa {
@args [ SRV BAT ]
@args.SRV {
type string
default {
@func refer

}
}
@args.BAT {

}
pcm.bluealsa {

Here's ~/asoundrc
root@Artisan:~# cat ~/.asoundrc

Here's what I get when I try to play mp3 file with aplay:
root@Artisan:~# aplay -D bluealsa:DEV=EB:06:EF:47:83:A6,PROFILE=a2dp,HCI=hci0 /ncsdata/Music/night.mp3

Here's what I get trying to play mp3 with mpd:
root@Artisan:~# /etc/init.d/mpd start
[ ok ] Starting mpd (via systemctl): mpd.service.
root@Artisan:~# mpc clear

root@Artisan:~# mpc stop

ERROR: Failed to open audio output
Error messages were identical after setting everything up by 1st and 2nd manuals. Speaker makes no sound of course. I feel that I'm near the solution, but can't figure out what am I missing. Googling aplay or mpd messages - no luck. I would appreciate your help.
