You play an audio file on a Windows 8-based or Windows RT-based computer. The sound is played from the computer speakers.
You pair a third-party Bluetooth audio device that supports Audio/Video Remote Control Profile (AVRCP) to the computer.
When the process that pairs and connects the audio device starts, the sound is still played from the computer speakers.
You set the paired device as the default audio device. The sound is played from the paired device.
You turn off the device and then the sound is played from the computer speakers.
You turn on the device again.
In this scenario, the sound is still played from the computer speakers.
The expected behavior is that sound is played from the paired device after the device is turned on.
Bluetooth headsets and audio devices can be paired to a Windows 8-based computer that lets users listen to audio by using Advanced Audio Distribution Profile (A2DP) or Bluetooth Hands-Free Profile (HFP).
This issue occurs because Windows takes longer than expected to disconnect the device. Normally, after you turn off a Bluetooth device, the device is disconnected from the computer in a few seconds.
