</div></div>Perhaps someone can say for certain if the ATI binary drivers are<br>
required for audio over HDMI... I would suspect that they might if you<br>
see no trace of the audio device on your system.<br>
<br>
One thing you might do is open a terminal and run "dmesg". this will<br>
give you the log generated by the kernel as it detects and configures<br>
drivers for your system. Scan through it to see if you see any sign<br>
that it loaded drivers for ATI audio, HDMI audio, or something like<br>
that.<br>
<br>
You might also do an "lspci" and take a look at the output of that to<br>
see if the device was even detected.<br>
<br>
There are a ton of tools at your disposal to check things out, however<br>
without any experience with your device I can't be sure what the best<br>
approach would be. Perhaps someone else can help?<br>
<br>
Personally, I always use the binary drivers from ATI or NVIDIA. While<br>
the ATI/AMD drivers are not perfect by any means, they are superior to<br>
the open source drivers included in Ubuntu, simply because they have<br>
access to information about the hardware that is not provided to open<br>
source developers.<br>
<br>
You do run the risk of X not starting, however typically this is<br>
easily fixed, and I don't see it happen very frequently, way too many<br>
users of those drivers for major issues like that to be ignored. Just<br>
make sure your system is fully updated before adding the video<br>
drivers... just in case your previous bad experience required a patch.<br>
