Why is the sound not working on Google Chrome, but it is on Spotify?

[faintnotebook515]

I have a windows 8 computer, and the sound does not work on chrome through my speakers. However, if I play, say, spotify through my speakers, it works fine. It is worth noting that I just got new headphones, and when I plugged them in and the sound works on chrome. However, when I open the sound mixer, the sound shows that it is playing on chrome, but none comes out. Are there any solutions? If additional details are needed in the synopsis, Just say and I will add in the additional details. Thanks!
By the way, I tried uninstalling and re-installing and it still does not work
Also since this started happening the loading circle on my mouse has started blinking. Not sure if they are associated with each other, just thought I would point it out in case.
