no this "quite" is related to output information from the process - like
debugging or verbosity.
the sound is managed by the driver
app -> sound library (alsa) -> driver (kernel) -> hardware
pulse sits between app and alsa - if you see indication in pulseaudio but no
sound, then the stream is not routed properly to the speaker - might be a
driver problem.
What you can do is check the kernel Documentation for that driver/sound card
you have.
Here some examples in linux-4.12.10/Documentation/sound/cards/
audigy-mixer.rst bt87x.rst emu10k1-jack.rst img-spdif-in.rst
joystick.rst mixart.rst serial-u16550.rst
audiophile-usb.rst cmipci.rst hdspm.rst index.rst
maya44.rst sb-live-mixer.rst via82xx-mixer.rst
$ lspci | grep Audio

$ cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20642
Codec: Intel CougarPoint HDMI
linux-4.12.10/Documentation/sound$ grep Conexant -r .
./alsa-configuration.rst:Module for Conexant Riptide chip
./hd-audio/models.rst:Conexant 5045
./hd-audio/models.rst:Conexant 5047
./hd-audio/models.rst:Conexant 5051
./hd-audio/models.rst:Conexant 5066
./hd-audio/controls.rst:Conexant codecs
The other approach would be - identify your codec and google linux+codec
it might be you need to provide some additional parameter to the kernel
driver. I recall one the HDMI was listed first and thus output went to HDMI
and not the standard sound system
