EDID captured from Krell using OpenELEC/Kodi instructions
I have a Krell Foundation non-4K which has a strange EDID. It does not have
one audio block with multiple SAD within it as do Marantz receivers but rather
it has several audio blocks, one after another.
When I connect the Foundation to an Asrock Beebox running OpenELEC the ELD data
structure ends up with only one element.
I think that is because of these lines of code starting at line 3157 in
intel/linux-4.0.4/drivers/gpu/drm/drm_edid.c
case AUDIO_BLOCK:
/* Audio Data Block, contains SADs */
sad_count = dbl / 3;
if (dbl >= 1)
memcpy(eld + 20 + mnl, &db[1], dbl);
break;
For the Krell, the sad_count would need to be incremented instead of just set
to the value from the EDID. I do not know how this code would keep all the
audio blocks in such a fashion.
Now, if you tell me that the Foundation is doing this incorrectly I am more
than willing to report that to Krell. ;-)
