I just purchased a Slingbox 500 and downloaded the app as well (for $14.99 of course). I have audio and video with the Slingbox, but when I use the Droid app, I get video but no audio. The volume on my phone is up all the way and I can hear audio from other videos, etc, but not with the Slingplayer app. Is anyone else having this problem? If so, what is the fix?
