Its been a longstanding issue that the audio on the MTV channel is witnessed on MTV base, MTV hits, MTV dance. To change the audio to what it should be on MTV base (as an example) its a simple matter of using the audio button on the remote control and selecting the English audio option. So that's all fine and good. The issue is if you now go back to MTV and the back to MTV base you have to set the audio option once again. In older vix builds you only ever needed to do this once and the system remembered the new audio setting. With the latest version of vix this is not the case
