Recently my HDMI sound has stopped working and my volume control does not show up. I have tried fixing this by reading a few other posted but to no avail. I have 64 bit ubuntu on an Asia G74 sx. My card is an NVIDIA 560m. Any help would be greatly appreciated!

Have you tried messing with ALSA?

type alsamixer into a termainal -- that usually my first bet.

Yes I have and the HDMI shows up there and is not muted...I have now managed to manually put the volume control back...but the HDMI does not show up there, only my laptop sound card and my digital output. Not sure if it will help, but I am currently uninstalling and reinstalling the NVIDIA drivers since it also controls the HDMI..

Reinstalling the NVIDIA drivers did not help :( I am officially stuck...is there a way to completely uninstall and reinstall the sound drivers?

I'm afraid your card (just like mine), does not carry sound over it.

You need to use another cable to carry the sound.

For instance, my TV has 2 hybrid inputs that allow video and sound come from different sources. One is an HDMI/RCA combo (which I'm currently using), and the other is VGA/mini-plug.

Depending on your TV and card, it may be also necessary an extra step: create a custom EDID file to extract the extra TV metadata to avoid a dummy sound signal.

Let us know how it goes.
Regards.

Ohh, I see.

I would upgrade your nvidia driver taking one step at a time to see if you get the audio driver. After each installation restart your computer.

Take a look at this post (http://ubuntuforums.org/showpost.php?p=11881731&postcount=2) to upgrade your driver.

Regards.

I ran both with no luck...should I just throw in the towel and reinstall?

when I do this




Add this ppa by the command
sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily
Update packages list
sudo apt-get update
Then install "alsa-hda-dkms" package:
sudo apt-get install alsa-hda-dkms


it says that it is not found....does that affect anything? nevermind..it now says it has the latest version....i have no idea whats going on with this thing.....I think maybe a reinstall may be my best option...
