If you have problems playing music on Windows
Go to the Apple Music app on your Windows device, then do any of the following if you have trouble playing music or other audio:
If the progress bar at the top of the Apple Music window is moving, but you don’t hear anything
If you’re using your computer’s built-in speakers: Make sure the volume controls are not turned down. Check the control at the top of the Apple Music window and check the computer’s output volume.
If you’re using powered speakers connected to your computer: Make sure the powered speakers are properly plugged into your computer’s audio port, plugged into a power source, and turned on. Also make sure their volume isn’t turned down.
If you can’t play a song
If you can’t play a song purchased from the iTunes Store: You may have exceeded the number of computers on which you can play your purchases.
If the song isn’t an iTunes Plus version, you can play it on up to five authorized computers. After you authorize five computers, you can’t play the songs on a sixth computer until you deauthorize one of the five authorized computers.
If the song is available as an iTunes Plus download, you can upgrade the song at the iTunes Store. See Usage rights for iTunes Store purchases.
If you’re trying to play an AAC file that was not created using Apple Music or downloaded from the iTunes Store: Songs you download from the iTunes Store or import into your library using the AAC encoder are encoded using the MPEG-4 AAC format. Songs in this format play in Apple Music and on your iPhone, iPad, and iPod. Other AAC files that you find on the internet or elsewhere won’t play in Apple Music.
If you’re listening to a playlist that includes a song preview: The playlist stops after the song preview. Double-click or double-tap the next song in the playlist to resume playing the rest of the playlist. A song preview in your library or a playlist has a button next to it showing the price.
If songs are missing or dimmed, see the Apple Support article If songs are missing from your music library after you turn on Sync Library.
