Hi there,
My plex collection is mostly 5.1 for better enjoyment on my living room system.
In my bedroom, I have a much cheaper system (Xiaomi TV + soundbar), but I’m having issue with sound volume. Even though I’m cranking the volume to 100%, it’s still very low and dialogs are typically quite hard to hear. For comparison, with other online media services I use, I can stick to 35% volume and that’s fine.
I tried the audio boost in the plex client, but I don’t think this is having an effect (?).
Is there anything I can do to improve the situation? And for my info: is downmixing done on the PMS, or the plex client in the TV? I don’t see any settings relating to audio volume either way, btw 
Thanks!
Tim
