Disabling sound over HDMI ?
 
Hello,

When using 169.xxx my TV could display a HDMI vid feed, and analog audio feed.

When going to 173.xxx and 177.xxx I no longer get the analog sound from my TV.
This is because with the 17x.xxx series, audio over HDMI has been implemented.
However, I rely on analog audio.

Is there any method available to disable the audio over HDMI in the 17x.xxx drivers?

Note that my TV plays the audio if:
* I do not start X
* I unplug the DVI cable
* I switch TV inputs.... I will hear sound for 0.5 seconds, after which it mutes again

It is nice nvidia implements new features, but audio-over-HDMI hurts existing users that rely on analog sound.

Thank you,

Bram

I believe you need to adjust the settings in your TV.

Include the usual bug report or this post will most likely be ignored. Per your previous posts you use a DVI->HDMI cable. This is information you need to include here.

Since nVidia has not released any documentation about audio over HDMI, none of us will be able to really help.

It is especially bad when they don't give us any way to configure it or even mention it being implemented. I am having the same problem[1] and it looks like the DVI->HDMI cable I bought at lunch isn't going to fix it[2].

My TV, Sony XBR-4 has no setting for this.

And there are people who are able to help out, ankh just solved it for me:

Sound-over-HDMI is disabled if you do
"UseEDID" "False"

This, however, has nasty side effects, so the best course of action (until nvidia implements a driver option) is to use "CustomEDID".
In short, you need to remove the extended block from the EDID you get from your TV.

OK, but wouldn't you think there should be an

Code:

Option    "HDMIAudio" "disable"
flag in your xorg.conf file? Or a checkbox in nvidia-settings? We don't know that though. Glad you found a workaround, but I sure hope there are less strenuous means of stopping audio over HDMI for less techno-savy users.
