* | object: speed up type verification by not relying on strcmp()Lennart Poettering2009-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using string contents for type identification use the address of a constant string array. This should speed up type verifications a little sind we only need to compare one machine word instead of a full string. Also, this saves a few strings. To make clear that types must be compared via address and not string contents 'type_name' is now called 'type_id'. This also simplifies the macros for declaring and defining public and private subclasses.
* | sink-input: add callbacks that are called whenever the mute/volume changesLennart Poettering2009-08-211-1/+15

* | sink: volume handling rework, new flat volume logicLennart Poettering2009-08-191-107/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - We now implement a logic where the sink maintains two distinct volumes: the 'reference' volume which is shown to the users, and the 'real' volume, which is configured to the hardware. The latter is configured to the max of all streams. Volume changes on sinks are propagated back to the streams proportional to the reference volume change. Volume changes on sink inputs are forwarded to the sink by 'pushing' the volume if necessary. This renames the old 'virtual_volume' to 'real_volume'. The 'reference_volume' is now the one exposed to users. By this logic the sink volume visible to the user, will always be the "upper" boundary for everything that is played. Saved/restored stream volumes are measured relative to this boundary, the factor here is always < 1.0. - introduce accuracy for sink volumes, similar to the accuracy we already have for source volumes. - other cleanups.
* | core: make fixed latency dynamically changeableLennart Poettering2009-08-151-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This of course makes the name 'fixed' a bit of a misnomer. However the definitions are now like this: fixed latency: the latency may change during runtime, but is solely controlled by the backend, the client has no influence. dynamic latency: the latency may change during runtime, influenced by the requests of the clients. i.e. fixed vs. dynamic is from the perspective of the client.

* | core: add assert macros for verifying calling contextLennart Poettering2009-08-131-5/+47
|/ | | | | | | This adds pa_assert_io_context() and pa_assert_ctl_context() in addition to a few related macros. When called they will fail when the current execution context is not IO resp. not control context. (aka 'thread' context vs. 'main' context)
* alsa: rework mixer logicLennart Poettering2009-06-171-5/+5
| | | | | | | | | | | | Completely rework mixer logic. This now allows controlling a full set of elements from a single sink's volume slider/mute button. This also introduces sink and source "ports" that can be used to choose different input or output ports with the UI. (i.e. "mic"/"line-in" or "speaker"/"headphones". The mixer paths and device maps are now configered in external configuration files and can be tweaked as necessary.

* core: use pa_{source|sink}_get_latency_within_thread() at one more placeLennart Poettering2009-04-141-4/+1

* core: introduce new 'reference' volume for sinksLennart Poettering2009-04-131-24/+31
| | | | | | | | | | | | | | | The reference volume is to be used as reference volume for stored stream volumes. Previously if a new stream was created the relative volume was taken relatively to the virtual device volume. Due to the flat volume logic this could then be fed back to the virtual device volume. Repeating the whole story over and over would result in a device volume that would go lower, and lower and lower. This patch introduces a 'reference' volume for each sink which stays unmodified by stream volume changes even if flat volumes are used. It is only modified if the sink volumes are modified directly by the user. For further explanations see http://pulseaudio.org/wiki/InternalVolumes
