There is no sound going from the HDMI port on my Nvidia card to my tv that I am using as a monitor. When I use my Logitech Headphones, I hear no sound either. Does anyone know how to rectify the situation? Here's some screenshots and system information (sorry if this is too much info):

  • Ubuntu Server 14.04
  • Fluxbox WM
  • SABERTOOTH 990FX/GEN3 R2.0
  • AMD FX(tm)-8350 Eight-Core Processor
  • GeForce GTX 660 Ti (Nvidia 331.20 Drivers)
  • Logitech G35 Headphone/Microphone

The volumes for the headset look normal, but the volumes for my HDMI output look like this:

In addition, nothing shows up in the HDMI tab in gnome-alsamixer
