[pulseaudio-discuss] [PATCH v2 00/22] Revisiting Bluetooth modules

[Mikel Astiz]

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

This patchset revisits the mapping between Bluetooth (BT) and PulseAudio (PA) states, as well as how the PA infrastructure and APIs fit the BT use-cases, including desktop and IVI use-cases. The topic has already been discussed several times in the mailing-list and IRC.

This third proposal (v2) basically includes bugfixes and minor refactorings.

The most relevant changes are:

1. Suspend case: now PA_SUSPEND_USER is used to represent audio stream is down (patches v2 12/22 and 15/22), instead of PA_SUSPEND_IDLE as in v1. The exception is when doing gateway role, where we start with PA_SUSPEND_IDLE (see patch v2 20/22).

2. Bug in patch v1 03/18: the patch was less trivial than it seemed first, and has now been rewriten into v2 11/22.

3. Patch v1 16/18 has been dropped since it's not essential now that PA_SUSPEND_USER is being used.

Therefore, the updated grouping of the patches would be as follows:

- Patches 1..9 propose minor changes, refactoring for later patches and some minor fixes (grouped in the beginning for readability).

- Patches 10..15 implement the new proposal for module-bluetooth-device. This is the main contribution of the patchset.

- Patches 16..21 focus on the integration with other modules.

- Patch 22 is experimental and should not be applied yet.

Looking forward for your comments.
