I have a Falcon board that has been acting goofy on me. At first I would get no sound, then it would come back. Then I got the artifacts, and finally  E74. I reflowed the GPU, the  E74 is gone but I have no sound. I have tried HDMI, Component and Optical. I checked all of the settings in the xbox and nothing seems to change. What I have done:

-Reflowed the GPU
-Reflowed Hana
-Reflowed SouthBridge
-Resoldered all of the points under the AV jack

Still no sound. Picture and everything else works great. This was all done on a T 870A IR station. Any help would be awesome Smiley

Yes, I had sound before all of this. Although the sound was intermittent after the reflow of the GPU the first time. Then just stopped after the 3rd boot up.

I was under the impression the the Hana scaler chip was to scale up the video image (720p, 1080p) etc...

I think it's a bad name that stuck.  The video resolution (and thus scaling) is most likely handled by the GPU. 

The HANA chip probably handles colour space and video/audio transport conversions.  It's more of a video encoder, converting RGB to YCbCr and contains component DACs, composite DAC, VESA driver, HDMI driver, etc.  Same deal with audio.

Did you reflow CPU? I read awhile back this fixed someone else's intermittent audio issue.
