I use volumio but that’s dedicated OS installation and it’s limiting in the sense of what other things can be done.

I’m looking to setup streaming to HTPC. What r my options?

I found uPnP is not advised due to security risk, however I didn’t see any other recommendation.

[EDIT] [UPDATE] now I understand why information was so lacking - because solution was just that simple. 😑

In gnome settings -> sharing -> enable media sharing.

Don’t need extra app or setup.
