Audio issues

[Scutum]

Hello!

I've got an issue with playing sound on audio_out 3.5mm jack connector. I've write my own application which need only to play a music file. When I start android os with hdmi plugged into board everything works great. But when I start android without plugged in hdmi cable, audio is missing.
Why audio out connector is not working without hdmi cable? How can I use audio out connector without hdmi cable?
I'm using A10S-OLinuXino-MICRO-4GB with android os provided by olimex.


Best Regards
