Haydn: Part 1 (#2007)
* Haydn: Part 1
Based on my reverse of audio 11.0.0.
As always, core implementation under LGPLv3 for the same reasons as for Amadeus.
This place the bases of a more flexible audio system while making audout & audin accurate.
This have the following improvements:
- Complete reimplementation of audout and audin.
- Audin currently only have a dummy backend.
- Dramatically reduce CPU usage by up to 50% in common cases (SoundIO and OpenAL).
- Audio Renderer now can output to 5.1 devices when supported.
- Audio Renderer init its backend on demand instead of keeping two up all the time.
- All backends implementation are now in their own project.
- Ryujinx.Audio.Renderer was renamed Ryujinx.Audio and was refactored because of this.
As a note, games having issues with OpenAL haven't improved and will not
because of OpenAL design (stopping when buffers finish playing causing
possible audio "pops" when buffers are very small).
* Update for latest hexkyz's edits on Switchbrew
* audren: Rollback channel configuration changes
* Address gdkchan's comments
* Fix typo in OpenAL backend driver
* Address last comments
* Fix a nit
* Address gdkchan's comments
