I just wanted to listen some music via youtube, but, guess what, no audio. And yes, i’m newbie
Even if i tried to find a clear and step-by-step guide regarding a ,how-to-setup audio" i didn’t found something relevant.
Long-short question: is able someone to provide this kind of guide? Because, unfortunately, on this forum just a ,mixed-salad" discussion can be found.
Sound works out of box on Qubes OS, at least for vast majority of users. That’s why there is no “guide how to setup audio”, because it just works (I am not talking about bluetooth or sys-audio complications).
So, you should diagnose and fix sounds issues for your case. But you provided no technical details of the problem, so it is hard to give any specific recommendations.
