I'm a total noob - how do I do this? I have ssh access, so can anybody tell me step by step how to make this change?  

1. ssh to your kodi
2. Get to the plugin's lib directory (from your home "cd .kodi/addons/plugin.audio.squeezebox/resource/lib")
3. Open the mentioned file in any console text editor you got - usually sth vi-like - vi player_monitor.py
4. Make the adjustments in the code. Should be around line 88. (If yousing vi editor, you need to press "i" inside the editor to insert mode)
5. Save the file (If using vi, then press escape (this quits the editor's insert mode), then type ":wq" (should appear in the bottom line of the editor) and hit enter)   

Great! Thank you.  

Fyi, I'm using LibreElec too and it doesn't come with vi for some reason (at least my install didn't). The best alternative editor that's already on it is nano. It's much more beginner friendly as it works mostly like how you'd expect notepad to work in a terminal, and most commands needed are listed at the bottom of the screen ('^' mean Ctrl).

Once you make edits to the file with nano just do ^X (Ctrl+X), then it will ask if you want to "Save modified Buffer" (meaning save your changes), hit 'Y'. It will ask where you want to save it but it will have the current file's path there as default, so just hit enter.
