You can play MP3's off of your USB key or if you've copied any to the **/mnt/storage** space with **btplay --start-daemon file.mp3**

MP3's will play in the background. To kill **btplay** run **killall btplay**

Audio will play through the headphone jack at max volume, just plug in your favorite headphones!

====== Playing remote MP3s! ======

You can also stream music with **btplay**, just stick a URL in there!

Just as before, just plug into the headphone jack to verify its working

====== Splitting out the A/V ======

The headphone jack is not actually just audio - its actually Audio and Video. That means that you if you just plug headphones you'll notice some buzzing - thats you listening to the video! Now if you're in a Cronenberg film this is probably OK but for most of us its very annoying! There are two solutions. One is to split out the 3 signals into RCA jacks (with a camcorder cable)

and then recombining with an RCA Y cable (such as [[http://www.sweetwater.com/store/detail/YRA154/|a Y female-RCA to male 3.5mm]] or [[http://www.sweetwater.com/store/detail/CMR206/|this]]


**Note** our A/V cables split out the signals as such - **Red** is Video, White and Yellow are stereo line-level audio

====== Using the Mixer ======

If you want to change the volume of the headphones, you'll need to run the audio mixer software **amixer**
