I'm running a Galaxy S3 (T999) running a rooted stock Android 4.1.2 and iGO Primo 9.6.22.317625 but I'm having issues with getting sound routed to either the headphone or HDMI output, it always outputs to the cell phone's back speaker.

So I'm looking to find out if there is a version that runs better at least sound wise on a cell phone, or a configuration that allows the sound to be routed away from the back speaker.

Thank you for your time and input,
Robert
