Consider the following scenario:
- You have a device running Windows 8 on an Intel Atom Z2760 chipset
- Windows Media Player or a 3rd party media application is playing an audio file through the computer's internal speakers
- You have a Bluetooth headset paired with the computer
This is a known issue.
To work around this issue, pause the playing audio prior to selecting or deselecting the "Recording" tab within the Control Panel/Sound applet.
The anomaly does not occur while playing audio with Windows 8 Music App.
