I am trying to enable noise cancelling following this guide.
However, I see that the
pulseaudio in my Zorin OS Pro is not the same with that in the guide, because at the end of the guide, I am supposed to run
pulseaudio -k, but the output suggests that
pulseaudio is not even running.
Just like that confusion was not enough, after searching for a fix, I stumbled upon the official Zorin doc on sounds. However, I noticed that the explanation in that doc does not apply to me at all
For example, the doc makes reference to
Zorin Menu → Sound & Video →... several times. However, on my own Zorin Pro, I only have
Zorin Menu → Sound →...
Also, the Playback section also showcases a UI that I do not have on my Zorin.
My confusion/question is: why the confusion/discrepancies?
