The co-working space I used to go right out of college used to have Sonos speakers. Occasionally, there'd be times when I wanted to work where the couches were but didn't want to listen to blaring pop music or something that was too rhythmic later in the day, so I started looking for ways to interrupt the audio stream going to the sonos devices. It turns out after a bit of snooping with nmap and looking at some Sonos forums that two specific ports are used to maintain sync between Sonos speakers and stream data to them. Then I just wrote a python script that would blast these ports with TCP traffic on the wifi (which the sonos speakers were also connected to) and would use the script when I wanted peace and quiet without headphones. Turns out that networking class I took in college wasn't a waste afterall.
