6 days agoRather than trying to get your idea to work you would be better off getting a cheep WiFi access point as they often allow you to connect it to a wifi network and pass it through to wired devices via ethernet (bridging).
Some Wifi routers have a setting to allow it to be used in bridge mode as well.
You will want to use something like Foobar2000 to scan the files then write replaygain metadata to each file.
Then you enable replaygain in VLC and it should work as you want.
