AC3IN
AC3, sold as Dolby Digital, carries up to six channels in one stream: five full range plus a low frequency effects track. DVDs, Blu-rays and broadcast television settled on it, so home cinema receivers decode it in hardware. When an AC3 track plays as silence on a laptop or phone, converting it to stereo AAC or MP3 clears the problem.
OPUSOUT
Opus is a modern codec aimed at real time sound. It encodes with very little delay, changes bitrate on the fly, and stays intelligible when bandwidth drops away. Voice and video calling tools use it for exactly that, and WebRTC treats it as the default. Music encodes well too, but standalone hardware rarely supports it, so convert before loading files onto an older player.
