Bug description:
  Hello there, it's my third or fourth session spending hours trying to
  debug why a Bluetooth headset would not work in HSP/HFP mode on my
  x230. The failure more is super obscure because at the time of error
  the only thing you notice is that no audio comes through in either
  direction. Using the a2dp_sink profile works fine.

  The root cause for the problem is simply missing firmware, which dmesg
  hints at during bootup:

  There are at least two firmware packages missing for different common 
X-series adapters; this is referred to from 
 and also https://wiki.gentoo.org/wiki/Lenovo_Thinkpad_T430.

  The actual firmware locations from those are:

  - 0a5c:21e8 https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd
  - 0a5c:21e6 
http://dlcdnet.asus.com/pub/ASUS/misc/BT/Bluetooth_V1201650_WHQL_Win10.zip (see 

  There is a lot of firmware collected here which may not be available
