This is my first time encountering an audio problem so I'm not 100% I went through the all basics, but here's what I've done so far:

• Verified my user is in the audio group
  
• installed pulseaudio and pavucontrol
  
• changed my default sinks to every option available with pacmd change-default-sink
  
• verified my volume was turned up in alsamixer
  
• played a known good file with aplay as local user and su
  
• tried a new headset, and tried the same headset in a different device. The headset is good.
  
• Searched this forum and followed Longsleep's recommendations posted here
  
• rebooted multiple times after iterating through these steps
  

None of these steps remedied the issue, and I still don't have any sound output. It's possible that it's sending the signal through the HDMI cable, but my monitor doesn't support audio so I can't tell.

I'm not sure what to do next, so here I am. Thanks in advance for any assistance.
PS. lspci produces no output. Is this normal?
