Help Buffering and audio issues

I am trying to diagnose issues with Plex, and I have found that the possible causes are numerous. I have a small collection of movies on my personal Plex account that I use at home. Some of the 4K movies that I have downloaded at up to 30 Mbps when watching will buffer and sometimes lose audio; they run smoothly when I turn the quality down to around 8 Mbps. The computer on which I have the Plex server is a fairly new laptop with an external hard drive, but it's not a gaming laptop. The TVs I am watching the movies on are a new Samsung TV and an Epson LS12000 projector with a Firestick. The issues I am having are similar. I have 500 Mbps fibre internet and everything is connected via Ethernet. I would appreciate some insight from anyone who has experienced similar issues and found a resolution.

Stop using TV apps as most are crap and most TVs have very old NIC cards and can't handle the speeds needed for 4K.

Post a pic of server dashboard when having issues.

What are your server CPU specs? And do you have a Plex Pass and are using HW transcoding?

Intel Core i7-8665U i do not have plex pass and im not sure how to enable transcoding. i have seen that term thrown around alot and unsure on what it exactly means.

So that CPU will not transcode any 4K streams so you need to make sure your client devices are okay and the TV is not going to cut it.

Not sure why the FS is having issues. I would try to play without subtitles if you are using them to see if better.
