OpenAudioOut
Takes two u64s (an interface ID and a PID placeholder?), a PID, a process handle, and the name of the interface you want to connect to. Returns an #IAudioOut object and four u32s: the sample rate, channel count, PCM format, and an unknown field.

1 | StartAudioOut |
2 | StopAudioOut |
3 | #AppendAudioOutBuffer taking a type 0x5 (A descriptor) buffer |

6 | ContainsAudioOutBuffer |

8 | #GetReleasedAudioOutBuffer taking a type 0x22 buffer |
GetAudioOutState
Returns an AudioOutState, 0x00=Started 0x01=Stopped
AppendAudioOutBuffer
Takes a u64 (not sure what this is, might act as some sort of identifier for the audio buffer? official applications seem to use the address of the audio buffer struct for this) and a buffer. The format of said buffer is as follows:
Offset | Size | Description |
---|---|---|
0x00 | 8 | Pointer to the sample data pointer. |
0x08 | 8 | Pointer to sample data. |
0x10 | 8 | Capacity of sample buffer |
0x18 | 8 | Size of data in sample buffer |
0x20 | 8 | Unknown. Zero works. |
RegisterBufferEvent
Returns an event handle that is signalled when a buffer is released
GetReleasedAudioOutBuffer
Takes a buffer, which it will fill with the identifiers passed from #AppendAudioOutBuffer of audio buffers that have been released. Will return a u32 (may indicate how many buffers were released?)
