* Make sure prebuf is filled when starting pulseaudio playbackChris Robinson2020-03-271-1/+25
|
* Use "zero-copy" writes with pulseaudio playbackChris Robinson2020-03-261-6/+20
|
* Move some setup to a more logical placeChris Robinson2020-03-252-34/+34
|
* Dynamically allocate voice channel dataChris Robinson2020-03-254-58/+48
| | | | | | | Rather than allocating for a full 8 channels for each voice, when the vast majority will only need 1 or 2. The voice channel data is relatively big since it needs to hold HRTF coefficients and history, and this will allow increasing the maximum number of buffer channels without an obscene memory increase.

* Use a busy-wait when synchronizing against the mixerChris Robinson2020-03-161-2/+2
| | | | | | | | The mixer should have higher priority than any thread that can make AL calls, so even on single-core systems, it shouldn't stall the mix. It will, however, return back to the caller as soon as it can, while yielding will give up the timeslice if there's any other thread waiting to process even if the mix is almost done.
* Fix voices being forced to update without valid propertiesChris Robinson2020-03-041-14/+7
| | | | | | | | | | | | | | | | When starting a voice, the source ID was set before its first update struct was provided, creating a small window where a listener or effect slot update could force a voice to update without it having any valid properties to update with. Supplying the update struct first would create a different race, where the mixer could see a voice without a source but with an update struct, causing the update struct to be 'freed' without being applied. The fix here is to provide the update struct before setting the source ID, and change the mixer to ignore update structs for voices without a source ID. This can pseudo-orphan the updates that get set on a voice just as it stops, leaving the struct unusable until the voice is used again, or the voice gets deleted which will clear it. But it allows the update struct to stay in place and get applied once the voice gets a source ID.

* Ignore VoiceChange objects while disconnectedChris Robinson2020-02-241-1/+25

|
* Use an array of ALvoice pointers for the active voicesChris Robinson2020-02-214-87/+96
| | | | | | This allows growing the array atomically with the mixer since the ALvoice objects themselves don't move, and a new larger array of them can be swapped in without blocking the mixer.
