Audio issues when playing via Chrome on local server

[Viriiguy 0]

I have an odd issue going on with a lot of my movies. The main audio track, containing the actors speech, goes VERY quiet, and the audio track with the music gets very loud, when I am playing it thru Chrome and the web interface, on Emby's local server. If I play the exact same file on any of my Kodi clients, using the Emby plugin, it works perfectly every single time. Both methods are Direct play, so no transcoding involved, I don;t think.

I cannot for the life of me figure out why it is doing this. Emby is fully updated and other than this issue, works fine.

Ok, i imagine this will be direct playing as you said. There is really not much we can do about this, as the browser video player handles this for us. Do you have another browser to compare with?

I did a bit more testing. It does it in every browser AND it does it in VLC. But not in the Emby app in Kodi. So I am guessing it is a VLC audio codec issue. I suspect that all my browsers are using that to play the file.

 

Thanks.

Well you have a video file with 5.1 channel audio. the video players are going to be down-sampling that to stereo so it's probably a question of which ones do a better job of it than the others.

I finally figured it out. It was the Realtek audio driver. Once I uninstalled it and installed a new one, audio is working fine across the board now.

 

Thank you for your help.
