HDMI audio not working on TV[Fixed]

[habahnow]

Hello all,
I have my computer hooked up to my tv via HDMI cable but not audio seems to come out of it. I have it dualbooted with windows 8, and the audio works there so i believe the issue is related to Linux Mint xfce 17.1.

I have messed around with with my Volume Control(by clicking on the speaker icon on the bottom right) and made sure that the output devices tab displays HDMI/DisplayPort. In configuration, the HDA Nvidia profile is set to digital stereo.

some things i have tried are on this link http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ where when i tried the "first alternate method", after restarting, my screen will stay black once i had logged in.

my inxi -Fx command yields:

Hey,

Sounds like a similar problem to what I had. When your HDMI is plugged in, try

Code: Select all

  pactl set-card-profile 0 output:hdmi-stereo

This re-routes your audio through the HDMI output. When you unplug it, you need to return the output to its normal place, with:

Code: Select all

  pactl set-card-profile 0 output:analog-stereo

(From a how-to located here)

Of course, you could make a script that does this at the press of a button (see that how-to for more info).

Good luck!
