ELD stands for EDID-Like Data. eld_valid=0 is a known issue in ALSA which has just been fixed upstream, but should only result in Radeon's multichannel audio being unavailable over HDMI. Stereo audio should still work with the radeon.audio=1 kernel boot parameter. If you have no audio with the proprietary driver then you definitely have a different bug. Isn't the ION an NVIDIA platform? Are you sure you were using the open-source Radeon driver and not the open source nouveau driver? Which proprietary driver did you try?
