interference.
Solution
Check connection of iPod mini in the docking station. Check connection of the
3.5mm stereo cable. Make sure it is connected to "line-out," "audio-out," or
the headphone jack on your sound card or other audio source — and NOT
"speaker-out."
Unplug the 3.5mm stereo cable from the audio source. Then plug it into the
headphone jack of an alternate source (e.g., Walkman, Discman or FM radio).
Check the operating system volume level and decrease if necessary.
Move the slider to the left to decrease the volume.
WAV and .MID files are often of poor quality; therefore distortion and noise
are easily noticed with high-powered speakers. Try a different audio source
such as a music CD.
Check the operating system volume level and decrease if necessary.
Move your speakers to see if the interference goes away.
