* Migrate hwopus

* Bye bye old audio service

* Switch volume control to IHardwareDeviceDriver

* Somewhat unrelated changes

* Remove Concentus reference from HLE

* Implement OpenAudioRendererForManualExecution

* Remove SetVolume/GetVolume methods that are not necessary

* Remove SetVolume/GetVolume methods that are not necessary (2)

* Fix incorrect volume update

* PR feedback

* PR feedback

* Stub audrec

* Init outParameter

* Make FinalOutputRecorderParameter/Internal readonly

* Make FinalOutputRecorder IDisposable

* Fix HardwareOpusDecoderManager parameter buffers

* Opus work buffer size and error handling improvements

* Add AudioInProtocolName enum

* Fix potential divisions by zero
