[alsa-devel] How is /proc/asound/cardX/eld#Y.Z generated?
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.
