CollapseOverview

When the BlackBerry Z10 smartphone is connected to a Bluetooth headset or other peripheral, no audio is outputted to the device. During a call, one-way audio may be experienced. When this occurs the other party will be able to hear the BlackBerry smartphone user, however incoming audio will be muted.

This issue can occur in the following scenario:

  1. The BlackBerry Z10 smartphone is muted.
  2. A Bluetooth peripheral is connected.
  3. A phone call is placed very shortly after pairing with the Bluetooth headset or system while volume information is being sent. 
  4. One-way audio occurs. At this point, using the volume keys will not resolve the issue.
CollapseResolution
This is a previously reported issue that is being investigated by our development team. No resolution time frame is currently available.
