* sink: volume handling rework, new flat volume logicLennart Poettering2009-08-198-270/+317
| | | | | | | | | | | | | | | | | | | | | | | - 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.
* source: rework volume handlingLennart Poettering2009-08-192-20/+27
| | | | | | | | | | | | | - drop the 'virtual_' prefix from s->virtual_volume since we don't distuingish between reference and real volumes for sources - introduce an accuracy for source volumes: if the hardware can control the volume "close enough" don't necessarily adjust the rest in software unless it is beyond a certain threshold. This should save a little bit of CPU at the expensive of a bit of accuracy in volume handling. - other minor cleanups

* core: make fixed latency dynamically changeableLennart Poettering2009-08-159-50/+210
| | | | | | | | | | | | | 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.

* thread-mq: never drop queued messages for the main loopLennart Poettering2009-08-141-0/+7
| | | | | | | | Previously we might have dropped messages from IO trheads to the main thread. This tuend out to be problematic since this cause SHM release messages to be lost. More visibly however this could cause playback freezing when moving streams between sinks and removing the old sink right away.

| | | | | | | 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)

| | | | | | | In some situations a rewind request travelling downstream might be optimized away on its way and an upstream rewind processing might never come back. Hence, call _process_rewind() before each _render()just to make sure we processed them all.
* core: save volume/mute changes coming from the hardware automaticallyLennart Poettering2009-08-074-25/+30
