* core: Add infrastructure for synchronizing HW and SW volume changesJyri Sarha2010-10-161-14/+83
| | | | | | | | | | | | | | | | To make concurrent use of SW and HW volume glitchles their application needs to be synchronized. For accurate synchronization the HW volume needs to be applied in IO thread. This patch adds infrastructure to delay the applying of HW volume to match with SW volume timing. To avoid synchronization problems this patch moves many of the volume and mute related functions from main thread to IO thread. All these changes become active only if the sync volume flag for a sink has been set. So, for this patch to have any effect it needs to be taken into use by sink implementor.

* 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: volume handling rework, new flat volume logicLennart Poettering2009-08-191-7/+5
| | | | | | | | | | | | | | | | | | | | | | | - 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/+15
| | | | | | | | | | | | | 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 Poettering2009-08-131-0/+7
| | | | | | | 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)
* core: save volume/mute changes coming from the hardware automaticallyLennart Poettering2009-08-071-2/+2
| | | | | Volume changes coming from the lower layers are most likely changes triggered by the user, so let's save them automatically.
* alsa: rework mixer logicLennart Poettering2009-06-171-5/+41
| | | | | | | | | | | | 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: introduce pa_{sink,source}_set_fixed_latency()Lennart Poettering2009-05-081-0/+1
| | | | | This allows us to forward the fixed latency directly from the sink to the monitor source withut having to wait for pa_sink_put().
* core: introduce new 'reference' volume for sinksLennart Poettering2009-04-131-4/+7
| | | | | | | | | | | | | | | 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
