No sound when playing back video

[rwklink]

I'm trying to play video clips in my Java application on a Nokia 6630.

The video is displayed correctly but somehow there is no sound.
I've tried using the VolumeControl to set a sound volume but with no results.

Can anyone explain what I need to do to play 3gp clips with sound?

hi,

is that .3gp file audible using native player on that device?

there is a similiar (no sound) issue with midi/wmapi on 6630 devices:
Mobile Media API does not play MIDI sounds
related to firmware version, is firmware version on your device within those affected fw?

regards,
Peter
