Hi. I was wondering if someone can tell me how exactly the eld files
are generated. Additionally, if they can be overridden somehow. The
reason is if I start x while my tv is turned on, the eld reports only
stereo audio capability for hdmi even though the tv is plugged into my
surround receiver. I don't care what the tv reports, my surround
receiver is 7.1 so I always want the eld to reflect my -actual- audio
channel setup.
Thanks.

It's just showing the data passed. Usually the graphics driver sets
ELD, and the hardware receives and transfers to the audio part.

No, there is no such a mechanism.

As mentioned, this is the information coming from the graphics side,
so the place to manage is rather the graphics driver.

Thanks for your reply Takashi, and for pointing me in the right
direction. Hopefully there's an override for this on the graphics
driver side.
