I use JRiver Server with my WiiM Pro and it works flawlessly. Newbie question about volume control in my streaming setup I'm an audiophile with a substantial library and I'm personally happy to support efforts like this, but I get that paying isn't for everyone. Your license will last forever, but you do need to pay for major version upgrades (once-per-year). It is available for Windows, Mac, and Linux. It's not free, but I'm a big fan of JRiver Media Center and have been using it for many years. What is the best mp3 player that also displays the album art while the file is playing?
