Soundtouch 30 static/crackle noises
I received a Bose SoundTouch 30 speaker as a gift recently, and the sound is mostly great. I've had this speaker about 2 weeks, and I just noticed that it is emitting a cracking/static type noise when it is powered on. This occurs whether or not any music is playing at the time. I have three total Bose SoundTouch speakers in my current setup. The other two SoundTouch 10 speakers do not have this problem.
The current set up in my home is:
1 SoundTouch 30 speaker
2 SoundTouch 10 speakers
All connected to same WiFi network, managed through the Bose SoundTouch app (iOS)
This product was purchased on QVC. If I have to return it, will I need the sale information?
