Audio stops shortly after BT profile is changed if this change happens immediately after device is connected.

Device 20:74:CF:32:CB:E1 Trekz Air by AfterShokz

Description of Problem:

If I have audio playing, then connect a BT device through A2DP and then change the profile to HSP/HFP in the following 1-2s after the device is connected the headphones get silent (VLC's progressbar keeps going)

To reset it I need to change the profile again.

If I wait longer than 2s after the device is connected to change the profile, it works flawlessly.

Until the audio is silenced, I can hear it in both A2DP (before the switch) and HSP/HFP (after the switch) qualities

How Reproducible:

I can reproduce it almost every time I try, tried with current master too (7c6649b5)

Steps to Reproduce:

  1. Have audio playing through speakers
  2. Connect BT device, notice audio playing with A2DP quality
  3. Change BT profile not 2s after 2, notice audio playing with HSP/HFP quality

Actual Results:

Headphones silent shortly after 3

Expected Results:

Headphones should keep playing (if I wait more than 2s in 3, this is what happens)
