where is module-solaris.so in pulseaudio 9 (solaris 11.4) ?

Hello,

Question: is there a modules-solaris.so module in the pulseaudio 9 package for Solaris 11.4 please ?

# pkg list -af pulseaudio

NAME (PUBLISHER)                                  VERSION                    IFO

library/audio/pulseaudio                          9.0-11.4.0.0.1.14.0        i--

library/audio/pulseaudio                          1.1-0.175.3.0.0.26.0       ---

library/audio/pulseaudio                          1.1-0.175.2.0.0.41.0       ---

library/audio/pulseaudio                          1.1-0.175.1.0.0.18.0       ---

on solaris 11.3  there is such a module in the package for pulseaudio 1.1 :

# pkg contents -r pulseaudio@1.1-0.175.3.0.0.26.0 | grep solaris

usr/lib/amd64/pulse-1.1/modules/module-solaris.so

usr/lib/pulse-1.1/modules/module-solaris.so

on solaris 11.4 there is none for pulseaudio 9.0 :

# pkg contents -r pulseaudio@9.0-11.4.0.0.1.14.0 | grep solaris

Background : I'm trying to get audio (sound) on a solaris 11.4 system.  I've noticed that when I plug in a usb sound card on this system the usb_as and usb_ac drivers are indicated in the "ddu" (device driver utility) of Solaris 11.4.
