I hooked up my trusty old Logitech speakers to see if they still worked. They did, so I booted a game and sheepishly turned the volume way down in fear of annoying my neighbors, immediately remembering why I had these stuffed in a closet for almost 10 years.
Even if I lived in a soundproof house in the middle of nowhere I'd still be self-conscious enough to just use headphones instead 
My partner and I play a lot of games either co-op or taking turns using her PC, so we need speakers. She doesn’t have desktop speakers though so we just use a portable Bluetooth speaker we already had
I used to have speakers plugged in all the time when I was still living at home and used to play games with siblings and friends in my room, so that checks out.
