Takes a type-5 input buffer ('''DeviceNameIn'''), a type-6 output buffer ('''DeviceNameOut'''), two u32s '''SampleRate''' (must be 48000) and '''ChannelCount''' (high u16 can't be 0, official apps pass 0xCAFE0000), one u64 '''ClientPID''', a PID and a copy-handle.
Takes a type-5 input buffer ('''DeviceNameIn'''), a type-6 output buffer ('''DeviceNameOut'''), two u32s '''SampleRate''' (must be 48000) and '''ChannelCount''' (only the higher u16 is used), one u64 '''ClientPID''', a PID and a copy-handle.
Returns an [[#IAudioOut]] object and four u32s: the sample rate, channel count, [[#PCM_format|PCM format]], and the initial AudioOutState.

Takes two s32s '''SampleRate''' and '''ChannelCount''' packed as an u64, an u32 '''WorkBufferSize''' and a TransferMemory handle for '''WorkBuffer'''. Returns an [[#IHardwareOpusDecoder]] object. The TransferMemory is created by the user-process with permissions=0.

Takes two s32s '''SampleRate''' and '''ChannelCount''' packed as an u64. Returns the u32 required size for the decoder's work buffer. Official user-processes align the output size to page-alignment.

Takes a type-0x19 input buffer, an u32 '''WorkBufferSize''' and a TransferMemory handle for '''WorkBuffer'''. Returns an [[#IHardwareOpusDecoder]] object. The TransferMemory is created by the user-process with permissions=0.
The input buffer is a [[#MultiStreamParameters]] struct. The user-process initializes this struct the same way as [[#GetWorkBufferSizeForMultiStream]], except that an u8-array specified by the user is copied to +0x10 with size '''ChannelCount''', when '''ChannelCount''' above 0.
