- Issue with returning a valid device descriptor
since BT SCO is not defined in IOProfile.
- With Android-Q changes, first attempt to retrieve device
descriptor from the avaiable HwModule may fail due to
address and encoded format conditions.
- Further device descriptor query is based on IOProfile
with devices defined in audio_policy_configuration.
- This change adds BT SCO to IOProfile.

The AC3, EAC3 formats are supported only when
license and respective decoders are present.
Having these entries in policy configuration
by default will unnecessarily trigger
open_output_stream and then fail when
decoders are not present. This results in
glitches at the begining of playback of video
clips with AC3 or EAC3 audio contents.
Removed these entries to make the video playbck
smooth with out any glitches.

No Audio heard in FM Speaker when FM record and FM speaker are on simultaneously
With default values for maxActiveCount and maxOpenCount,
FM app is unable to record and play FM audio on speaker simultaneously
since it uses application loop back(AudioRecord->AudioTrack)
to route FM audio to non-default devices(Speaker)
Add attributes maxActiveCount="2" and maxOpenCount="2" to mixPort "primary input"

* Speaker isn't properly calibrated with ACDB from O-based MIUI (while
it was on N), pop is heard when disabling speaker.
* MIUI has speaker protection enabled, hence this route isn't even
used by Xiaomi. However, with speaker protection enabled on Lineage,
the volume curve became very strange, maybe Xiaomi uses Dirac audio
effect to address this issue on MIUI, but it's not supported on AOSP.
* Fortunately voice speaker seems to be properly calibrated, so apply
that route to fix the issue.
* Voice speaker gain in ACDB seems to be lower than speaker, so
slightly increase gain in mixer paths to make it sound like a "normal"
speaker.
