No local speech/sound output with TTS system

[HomeRun]

Hi,

thanks first of all for this awesome piece of work.

I'm currently using openhab 1.3.1 on Debian wheezy 7.2 with openjdk-6-jre and alsa enabled.

When using the marytts addon I ran into the problem that no local speech output was possible on the server running openhab:

In the openhab log (with default debug settings) I discovered that the following LineUnavailableException occurs after a say(..) commands either issued directly on the osgi console or during a Startup rule:

18:48:55.475 DEBUG o.o.m.r.i.engine.RuleEngine[:277] - Executing startup rule 'Startup'

I checked that alsa sound is working on the system without problems:
# alsamixer
# aplay /usr/share/sounds/alsa/Front_Left.wav
and I was able to hear the respective sound file on the line out port.

MaryTTS seems to work well looking at the logs:

Does anyone know how to debug further to see why the LineUnavailableException is thrown by the JVM? (I cannot find any process blocking access to the audio line..)

Any help on this is appreciated.

Thanks in advance

Hi Homerun,

I assume you use OpenJDK. I had the same Problem. I solved it by changing OpenJDK7 to Oracle Java. Now OpenHab speaks to me.
