Recently, I saw this same issue on an iPad so I decided to post my solution.
Using mkvinfo then mkvextract extract the 7.1 stereo audio from the MKV container. Matroska is a multimedia file format aiming to. With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. This issue with audio codecs is also present in other TV manufacturers like Sony, Samsung, Panasonic or LG. In addition, videos with AC3 audio can’t be played in Apple devices like iPad, iPhone, iPod, Apple TV, etc. You can probably do it with ffmpeg, Ive never done it myself, Ive only converted 1-channel and 3-channel (rare) audio to 2-channel. MKVToolNix is a set of tools to create, alter, split, join and inspect Matroska files (mkv). MKVToolNix consists of the following command-line tools: mkvmerge is a tool to create Matroska & WebM files from other formats. It is the de-facto reference implementation of a Matroska multiplexer. Then, I tested several programs and finally found the perfect combination. MKVToolNix is a set of tools to create, alter and inspect Matroska & WebM files under Windows, macOS, Linux and other Unices. I had this audio issues on a RCA TV. First, I did some research about the supported codecs and containers for the TV. On the other hand, no licenses or payments are needed to stream or distribute content in AAC format. Thus, some companies choose not to pay and do not support them.

The reason for this is that those audio codecs have patents and a commercial license must be paid in order to decode them. Many devices do not support videos with AC3 or DTS audio, among other codecs. In other words, the video is played but with no sound.
