I ask you again – which image did you use? On our website are more than one image. Do you use the default image? Or the HiFiBerry Image?
2. Do you use some additional devices with the raspberry? Something like a usb dongle or a external hard drive?
3. Which power supply do you use?
4. Please try to stop Squeezelite if you get the problem.
5. Please take a look into the advanced settings of the squeezelite player (you will find it in the Audioplayer menu) and tell me what is in the textbox for the command line options.
