[pulseaudio-discuss] [RFC v1 0/6] Add card profile availability

[Mikel Astiz]

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

Second proposal integrating Tanu's comments:
1. pa_availability_t used for both port and profile availability.
2. Carefully consider profile "off" in automatic profiles witch policies.
3. Availability of "bluetooth-input" and "bluetooth-output" handled separately.

>From original cover-letter:

It has been recently discussed how ports should be used in the Bluetooth card module, whether they should be merged or not, and how the bluetooth-related information is exposed to both external components (i.e. UI) and internal policy modules.

In a nutshell, the problem is as follows: the internal policies are interested in profile-specific information (HSP/HFP vs A2DP) while the ports should ideally be associated to physical entities (and the Bluetooth profile should make no difference).

A natural way to solve this problem is by adding a new flag to the card profiles, representing the availability of each profile. This is similar to port-availability but with different semantics, representing the state of each invidivual Bluetooth profile.

This patchset extends the core with such a flag, which sounds useful even beyond the scope of this specific problem (a UI could use this information to gray out profiles).

Mikel Astiz (6):
  core: Rename pa_available_t to pa_available_t
  card: Add card profile availability
  cli: Show card profile availability status
  bluetooth: Expose card profile availability
  bluetooth: Use profile availability to auto-switch profiles
  bluetooth: Merge all ports into "bluetooth-input" and
    "bluetooth-output"
