Takes a type-0x6 output buffer containing an array of [[#AudioOutInfo]]. Returns an u32 '''Count'''.
Populates the output buffer with the available audio output devices' names and returns an u32 with the number of device names written.


== OpenAudioOut ==
== OpenAudioOut ==
Takes a type-0x5 input buffer ('''DeviceNameIn'''), a type-0x6 output buffer ('''DeviceNameOut'''), two u32s '''SampleRate''' (must be 48000) and '''ChannelCount''' (only the higher u16 is used), one [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], a PID and a copy-handle.
Takes a PID-descriptor, a type-0x5 input buffer '''NameIn''', a type-0x6 output buffer '''NameOut''', an input [[#AudioOutParameter]], an input Process handle and an input [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]]. Returns an [[#IAudioOut]] and an an output [[#AudioOutParameterInternal]].
Returns an [[#IAudioOut]] object and four u32s: the sample rate, channel count, [[#SampleFormat|SampleFormat]], and the initial AudioOutState.
