Surround Sound Studio (PPSA99051), catalog build on main a11c8f7f with
the flat-interpolation fix, stops 16 s in, before its first frame
(orishamir, #3581 comment 6109839314):
sceAudioOutSysGetHdmiMonitorInfo not implemented
The call takes (type, out, size); out must be non-null, size exactly
0x180 and type 1 (HDMI) or 0x10 (sainsaji/PS5-Audio-Passthrough-Research
c3be9c2a, docs/FINDINGS.md section 3 and AGENTS.md:25, firmware 12.70).
Titles read the monitor name at +0x0B, the descriptor count at +0x94 and
8-byte descriptors from +0x98 (same, FINDINGS.md hardware log item 1 and
sample-app/src/platform/ps5/bitstream_out.cpp:92-128).
Audio reaches the host through SDL as PCM and there is no EDID, so type 1
with a 0x180-byte buffer reports a sink without a name or descriptors:
the buffer is zeroed and 0 is returned. Surround Sound Studio's
Passthrough page then lists no formats; EVO Player's code treats an empty
list like a negative return. A null buffer returns 0x80260004, as the
other AudioOut calls do. Type 0x10, other types and other sizes throw:
their results and error codes are not known.
