Surround Sound Studio (PPSA99051) opens an Ex port for IEC 61937 bursts
when a clip is played. Follow the disassembly and console log in
sainsaji/PS5-Audio-Passthrough-Research: ExOpen refuses modes outside
mask 0x61F with 0x80260015 and opens an S16 stereo port of 256 frames at
48 kHz or 1024 frames at 192 kHz; ExConfigureOutput refuses a nonzero
first argument with 0x80268009 and returns 0 for the documented modes
and targets; ExClose returns 0. The host has no HDMI bitstream output,
so an Ex port has no device and drops its bursts at its own rate.

Jelly5 (PPSA99505) imports sceAudioOutExGetMonitorInfo (PhnNN0UEV6Y),
sceAudioOutExConfigureOutput (VcE+gXSwFXI), sceAudioOutExOpen
(6X6dp+07h4U) and sceAudioOutExClose (0TfjSulCV2A) from libSceAudioOut
and fails to load because no library exports them. It calls them only
for its optional HDMI bitstream output, and their signatures are
unconfirmed, so they are exported without an implementation and throw
if they are called, like sceSaveDataCancel.
