I just ran test to see where my problem lies... and it turns out to be with the PC/Myth/Ubuntu.<br><br>I pulled a dvd player that had DVI out RCA audio and I hooked it through the HDMI1 port on the tv and I got both sound and video.<br>
<br>[EDIT]<br><br>I found a post that describes my issue to a "T" (<a href="http://forums.nvidia.com/lofiversion/index.php?t88272.html" target="_blank">http://forums.nvidia.com/lofiversion/index.php?t88272.html</a>) and modifying the xorg worked but now the picture is jacked up...<br>
<b><br>Section "Screen"<br> Identifier "Default Screen"<br> Monitor "Configured Monitor"<br> Device "Configured Video Device"<br> DefaultDepth 24<br>
Option "ExactModeTimingsDVI" "True"<br> Option "UseEdid" "FALSE"</b><br><br><br>Below from the NVidia appendix doesn't seem to have the option for only turning of the sound, anyone else have any ideas???<br>
<br><dl><dt><b><span><code>Option
"UseEdidFreqs" "boolean"</code></span></b></dt><dd>
<p><b>This option controls whether the NVIDIA X driver will use the
HorizSync and VertRefresh ranges given in a display device's EDID,
if any. When UseEdidFreqs is set to True, EDID-provided range
information will override the HorizSync and VertRefresh ranges
specified in the Monitor section. If a display device does not
provide an EDID, or the EDID does not specify an hsync or vrefresh
range, then the X server will default to the HorizSync and
VertRefresh ranges specified in the Monitor section of your X
config file. These frequency ranges are used when validating modes
for your display device.</b></p>
<p><b>Default: True (EDID frequencies will be used)</b></p>
</dd><dt><b><span><code>Option
"UseEDID" "boolean"</code></span></b></dt><dd>
<p><b>By default, the NVIDIA X driver makes use of a display device's
EDID, when available, during construction of its mode pool. The
EDID is used as a source for possible modes, for valid frequency
ranges, and for collecting data on the physical dimensions of the
display device for computing the DPI (see <a href="http://http.download.nvidia.com/XFree86/Linux-x86/1.0-8774/README/appendix-y.html" title="Appendix Y. Dots Per Inch" target="_blank">Appendix Y,
<i>Dots Per Inch</i></a>). However, if you wish to disable the
driver's use of the EDID, you can set this option to False:</b></p>
<pre><b> Option "UseEDID" "FALSE"<br></b></pre>
<p><b>Note that, rather than globally disable all uses of the EDID,
you can individually disable each particular use of the EDID;
e.g.,</b></p>
<pre><b> Option "UseEDIDFreqs" "FALSE"<br> Option "UseEDIDDpi" "FALSE"<br> Option "ModeValidation" "NoEdidModes"<br></b></pre>
<p><b>Default: True (use EDID).</b></p>
</dd></dl><br></blockquote><div> <br><br>Another option I found for resolving this is to edit the EDID file directly. I'm a bit ignorant to using a hex editor so maybe someone could help me out that??

<br></div></div>In essence I need to get xorg.conf to load up the file like so<br><br><b>Option "CustomEDID" "DFP-0:/etc/X11/samsung.bin"</b><br><br>and then edit the .bin file in a hex editor as described below... maybe it will work.<br>

<b>"I got the TV EDID dump from the Xorg.log, amputated the Extension Block
data (anything after byte 127, 0 base), reset the Extension Block count
to zero (byte 126) and incremented the checksum by 1 (byte 127) and,
tada, the 9500GT now doesn't send the audio over DVI, meaning the TV
now plays back the RCA audio."</b><br><b><br></b>Any help would be appreciated with this as I know nothing about editing in a hex editor.<br><br>Thanks.<br><br>AJM,<br>
