I am using Chromecast 2 and facing an unusual situation. Whenever I am connecting my Chromecast to Wi-Fi, it is picking up an unknown frequency - probably a radio or tv station. The sound is very noisy and unclear, but it's definitely a channel streaming. My set top box for tv is also plugged in side by side of Chromecast. Please explain how this can happen and how to resolve the issue.

Hello, thanks for taking the time to post your issue.
Does your supported sending device (e.g phone), TV or router have a task killer app, standby, firewall, antivirus, sleep mode, power saver, a parental control, tv HDMI-CEC settings, wifi network extender, or electromagnetic devices (stereo receiver, DECT cordless phone, microwave, baby monitor, refrigerator, LCD monitor, etc) causing interference?
Are there any cables connected to your tv or another device that has a fault cable connector?
If you have DECT or baby monitor, or other bluetooth devices, make sure their batteries are fresh and check their user manuals about changing channels. Speaking of channels, if you have an Android device, install the Google Play app, Wifi Analyzer and run it. Your wifi router may be on a congested channel. Try channel 1, 6 or 11. Not Auto setting.  Please keep in mind that resetting or making changes to your router settings may have unintended consequences. If you have questions or concerns, please consult your router manufacturer or Internet Service Provider before making any changes. See What router settings do I need to set up Chromecast?

A microwave can sometimes introduce noise in the wifi spectrum. However, if you are not experiencing any video anomolies or artifacts and it is isolated only to the audio channel, that would indicate a problem with the source generation device's hardware (your Chromecast). Probably a bad solder on the board or a loose connector within the Chromecast itself. I would send it in for repair if Google offers such a program. Otherwise, might need to bit the bullet and buy a new Chromecast.

Sorry for the grim news :/
