Mirroring display

I am on Huawei Mediapad M5 - Android. Trying to remote control my Wondows7 Home PC device.

Issue 1. There is no audio ( using the TeamViewer app there is audio- although with that app there other problems )

Issue 2. Using Jump Desktop and tapping my Tablet makes very hard to control my AudioEditor program on my PC. SO my question is: how to use Jump Desktop as simply a clone of my PC display ? Since I have a bluetotth keyboard and mouse - and I only go to the other room, I want to use my OC's own keyboard and mouse.  But I cannot see the PC mouse cursor on JUmp Desktop , only my tablet's "own" cursor.  Is it possible to switch it off ?
