plex media server raspberry pi usb drive

I am comfortable with the terminal and nano/text editors but I am unsure what commands or edits to make this work. Unfortunately (difficult part), there are not a lot of guides online on how to tell ALSA/MPD not to mess with the audio stream, as by default it either down-samples or up-samples the stream. I have installed Plex Media Player onto the Pi4 2GB running Raspberry Pi OS with Desktop and plan to install Spotify Connect, Airplay, and DLNA packages.

My current solution seems like it will work but be fairly difficult. I tried running LibreELEC with the Plex addon and that also was a flop, being incompatible with the Plexamp app on my phone and iPad. I bought a Pi4 2GB thinking that I would run RaspPlex but it was a massive flop due to the lack updates in 4 years. I am trying to figure out how to easily stream both Tidal (might migrate to Spotify Hi-Fi when it launches) and Plex to my bedroom setup for my HD800S. Additionally, I am hoping to get this setup on a Pi for myself so I can also image it, flash it on another microSD card, and send to my dad for his much more expensive speaker system. Since I already pay for Plex and require remote streaming Roon is not an option (plus it is incredibly expensive). My Plex music server runs off a Raspberry Pi4 8GB (Ubuntu MATE) and I regularly stream both on my internal network and over the internet.

I pay for and use Plex on a daily basis for both music (FLAC) and movies/TV. I am a long time lurker (first post!) and have a unique set of needs for my music server.
