I am having some audio issues with the Slingbox 350. The audio keeps breaking up when watching movies while there is only low volume background music or noise and nobody is talking. This happens with all clients that I have tried (Web, Android, WDTV). It appears, the Slingbox is trying to mute the sound completely if it is below a certain volume level.
The general audio output volume of my cable box (Cisco Explorer 8642PVR) seems to be somewhat lower as compared to the volume level of other A/V sources (this is quite noticeable on my TV as well). Unfortunately, there doesn't seem to be a way to change that on my cable box. However, these audio breaks are definately introduced by the Slingbox and not the cable box. I have tried other Slingboxes and get the same issue with the Slingbox 500. The Slingbox 300 however does not suffer from the same problem.
