[pulseaudio-discuss] [PATCH v1 2/3] bluetooth: Disable profile auto-switch policy for headsets

[Mikel Astiz]

From: Mikel Astiz <mikel.astiz at bmw-carit.de>

Given that headsets have just one single port exposing whether the
audio is streaming (playing) or not, it's not possible that
module-bluetooth-policy would distinguish A2DP/HSP cases, and thus
the automatic selection of the card profile is not deterministic.

For this reason, disable the policy entirely for headsets and focus
only on HFGW and A2DP source profiles.
