I’m using Raspberry Pi 3B (RPI3B) as a media server and experiencing extremely weak audio. My primary media server is a home-built pc running kodi 18.9.0 on a linux mint OS (18.3). audio/video is routed through my receiver/amplifier, and displayed on a Visio 55-inch screen. ‘Ripped’ movies (from my personal DVD collection) play beautifully on this system.
My secondary media server is a RPI3B running OSMC 2020.11-1 (OSMC running Kodi 18.9). The purpose of the secondary media server is the ability to transport and view movies remotely in my RV. NOTE: Currently no wifi in the RV campground. The RPI3B/OSMC serves only as a video player. Movies are downloaded from my primary system to a 256GB memory stick. The stick is separately powered (with the RPI3B) using a powered USB drive. Viewing in the RV uses the 3.5mm audio jack to composite connection to an old 4:3 TV. Video is acceptable. However, the audio is extremely weak.
I have connected the RPI3B to my primary media server using HDMI, and audio is extremely weak compared with the original movie.
It seems to me that as the movie located on the memory stick is a direct copy of the movie on my primary media server, there should be no reason for audio differences.
Can anyone recommend settings that might need to be changed to remedy this?
