I'm really confused as to why no sound is coming out of the speakers or headphones. Ubuntu seems to recognize all of the devices just fine. From the attached images you can see the audio meter is moving while I'm playing music. I've included the settings screen and the alsamixer output. I can't seem to find anything online to even really troubleshoot this. Any troubleshooting suggestions would be helpful.
When I use sudo dmesg | grep -i sound", here is the result I get:
