play soundmessage with BT

[johnnie]

Hi guys, hopefully somebody can point me in the right direction.

I've installed an BT dongle with the help off: https://www.domoticz.com/wiki/BTAudio, and this working perfect, thnks!

When I launch the command from cli, it's working like a charm:

Code: Select all

mplayer -ao alsa:device=bluetooth /media/alarm_ingeschakeld.mp3 -softvol -volume 30 -af resample=16000:0:0

Then I've integrated it in a bash script named: alarmaanmp3. This script contains:

Code: Select all

#!/bin/sh
mplayer -ao alsa:device=bluetooth /media/alarm_ingeschakeld.mp3 -softvol -volume 30 -af resample=16000:0:0

When I run this from cli, it's also working:

Code: Select all

/home/pi/domoticz/scripts/alarmaanmp3

Now comes the part I got stuck, I've made a dummy swith and put the command in the "on" part of it (did the same for "off", but this has the same results):

messagealarm.JPG (37.25 KiB) Viewed 2122 times

In the log I see the script got activated, but no sound.

After this I've changed to LUA and made the script, named: script_device_alarmmessages.lua.
This script contains the following code:

Code: Select all

commandArray = {}
  if (otherdevices['AlarmActive'] == 'On') then
    os.execute('/home/pi/domoticz/scripts/alarmaanmp3')
    print('Alarm message -aan- verstuurd naar BT-speaker')
  end
return commandArray

I can see the print output in the log, but also here no sound.........

Hopefully somebody can help me with this puzzle.....

btw: I'm running Version: 2.3530, Build Hash: 9eef872, Compile Date: 2015-11-01 11:41:18

try giving it the full path to mplayer, run 'whereis mplayer' to find its location.

I take it your scrpt is executable? chmod +x /home/pi/domoticz/scripts/alarmaanmp3

you might try using #!/bin/bash instead of sh, I am finding alot of little arm boxes that come with a default shell that sucks at scripting.

Hi nayr,

Thnks for you're prompt response, script was indeed executable but checked it just to make sure.
Found mplayer and placed full path in the script, also changed it to bash, now I've got:

Code: Select all

#!/bin/bash

/usr/bin/mplayer -ao alsa:device=bluetooth /media/alarm_ingeschakeld.mp3 -softvol -volume 30 -af resample=16000:0:0

Still no luck.

A friend of mine maringo, also on this forum, thinks it got something to do with "rights". As mentioned earlier I've completed the setup from wiki under the user "pi". Is this oke, or had I done it under "root"?
maringo also suggested to run: "sudo mplayer" instead of "/usr/bin/mplayer".
But when i do this i get the folowing output:

Code: Select all

Find the solution with the help of maringo, what dit the trick?

First I created a root password with the help of: "sudo passwd root" procedure and logged in under root with the newly created password.
Then I created the file .asoundrc under the directory root containing:

Code: Select all

## Redirect all sound via Bluetooth
pcm.bluetooth {
        type bluetooth
        device AA:BB:CC:10:20:30 # change this MAC address to your speakers address
        profile "auto"
}

Then I've put sudo in front of the comment in the scripts I've created before. They are now (btw I've created one for "off" and one for "on"):

Code: Select all

#!/bin/bash

sudo /usr/bin/mplayer -ao alsa:device=bluetooth /media/alarm_ingeschakeld.mp3 -softvol -volume 90 -af resample=16000:0:0

Then rebooted the pi and yes it's now working with the dummy switch!

Thank you all, and hopefully somebody else can benefit from this thread as well.
