sound disappeared on HTC one X

[helpme1]

I have currently a premium spotify account. For some weeks(!) now the sound on my spotifymusic have been gone. When I start a track, it seems to be playing, as the timeline moves, but there is no sound. There is no problem with the general soundfunction on the phone what so ever, only when I'm using spotify on my phone. Spotify on my computer works fine.  I have followed every step on the "[Android] Troubleshooting Spotify". But when I uninstalled the spotify-app (step 5), and turned my phone off (step 6), I couldn't find any of the spotify folders:  "com.spotify.mobile.android.ui" on my phone (step 8), so I couldn't delete "them". When I started spotify again, there was still no sound! I hope to get some help with this problem.

This is similar to turning off your phone but try holding the Power button and the volume down button. On HTC One phones, this'll achieve the same effect of removing the battery on other Android phones, which often solves this.
