Change live TV default audio stream

Hi

I’m using the DVBlink PVR addon with Kodi 17. Not sure if this is a Kodi or DVBlink addon issue.

The problem I’m having is that when watching tv Kodi is defaulting to the first audio stream, which in my case is descriptive audio. I need to default to the second stream (which is English) for all channels but I can’t seem to find a way to globally set this. Am I missing something or is this feature missing?

Cheers!
