[mythtvnz] Next problem --- Audio over DVI to HDMI

I have an older Panasonic 42" and nothing else. I tried for ages to do HDMI
audio. Between the loud pops and crackles when starting video, lack of AC3
support on the TV and the occasional complete loss of audio I gave up and
went back to analog.

Because I like to use the volume control on the Myth remote (and not on the
TV remote), I had to turn on the software mixer, which in my case was fairly
craptastic when dealing with digital audio.

Yep, this happened to me too. You need to run a startup script which quietly
loads up the nvidia settings when Gnome starts.


First, just make sure you have a *~/.nvidia-settings-rc* file, with your
overscan settings already in them. This *should* already be present because
they load OK when you run nvidia-settings manually. Check for a line like
this (yours will probably say 100 I guess):

0/OverscanCompensation[DFP-0]=65


Then, create a Gnome startup file called *
~/.config/autostart/nvidia-settings.desktop*, then restart GDM or
logout/login or reboot:

[Desktop Entry]
Type=Application
Exec=nvidia-settings -l
Hidden=false
X-GNOME-Autostart-enabled=true
Name[en_NZ]=Nvidia Settings Apply
Name=Nvidia Settings Apply
Comment[en_NZ]=
Comment=


I'd be interested to hear how you get on.
