 - [sceAudioOut2PortCreate](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Port.cpp) (libSceAudioOut) - 12 channels are assumed to be L R C LFE Ls Rs Lb Rb Ltf Rtf Ltb Rtb as in KytyPS5's 12-to-8 fold, and 6 and 8 channels to be its first 6 and 8; no title or SDK header confirms the order
 - [sceAudioOut2PortCreate](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Port.cpp) (libSceAudioOut) - the stereo fold is assumed, not the console's downmix: C at -3 dB into both sides, Ls/Rs, Lb/Rb and Ltf/Rtf at -3 dB and Ltb/Rtb at -6 dB into their own side, LFE dropped
 - [sceAudioOut2PortSetAttributes](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Port.cpp) (libSceAudioOut) - each PCM buffer set (attribute 0) is taken as one grain: buffers set between two pushes are queued and played one per grain, at most 16 queued. A grain with no new buffer repeats the last one only when the port has always been given that same buffer (rewritten in place); a port whose buffers move on plays silence instead. Inferred from PPSA12544, whose object port (type 6) is given one grain of a 64-grain ring per set, often two or three between pushes and then none for a few; the console behaviour for several sets per push and for a push without a new buffer is not documented
