i ran the video player (http://davanum.wordpress.com/2007/12/29/android-videomusic-player-sample-from-local-disk-as-well-as-remote-urls/) on Android ARM9 hardware device. While i can view MP4 and 3gP videos , i cant hear any sound. ALSA support is already added to my kernel image and my sound hardware driver is also ALSA compatible.
Any idea what is happening ? Is android using a different sound interface ?
