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.
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. PCM format 2 is INT16.

=== 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:
{| class="wikitable" border="1"
{| class="wikitable" border="1"

| 0 || RequestSuspendAudioOuts

Returns an event handle that is signalled when a buffer is released

Takes an [[AM_services#AppletResourceUserId|AppletResourceUserId]]. (u64)
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?)
