Raspberry Pi B rev 2 does not add to playlist or play

Hi everybody,

first, sorry for my english.

I installed Volumio for the first time on my Raspberry Pi. I want to use the integrated audio output for testing before i buy an extra DAC. The software runs and i can access the web interface.

Unfortunately i cannot add mp3 from a usb stick or webradio streams to playlist and cannot play them.

My Settings:

  • Playback
    [*]Audio Output: Alsa

  • Mixer Type: Software

  • Resapmling: disabled

  • I2S Driver: None

  • Kernel profile: default

Has anyone an idea what i am doing wrong?

Thanks for your help
