The audio streamed to a headset in a multipoint configuration will be
// distorted when the link to a second device is lost and the headset tries to
// reconnect to it. This will result in distorted audio being played to the
// speaker.
//
// This patch stops the headset from attempting to reconnect to a link that has
// been lost if it is receiving A2DP audio on another link. This minimises the
// impact of the lost link on the streamed audio resulting in little or no audio
// distortion.
//
// The patch uses the ACL closed indication to only indicate a single link-loss event.
