Hi Raymond

01). I am stuck trying to query the channel map. chmap script won't run on my OpenELEC system. Here's what the SSH session did:

Is there a way to make this portable enough to run on my stripped down system ?

02). Regarding the Audio data block you extracted from EDID above:

a). Although "max channels" value is specified, what enumerates specific configurations supported by the device ?

In my case, 2.0 and 5.1 are the only recognized channel maps. Since the AVR is "only" HDMI v1.1 compatible, is it possible the EDID does not transmit full channel map info ?

b). Would it be possible to create a "full spec" EDID.BIN (to use as override), that reflects the D2's available channel formats, and thus cause ALSA to send the 4.0 material on 5.1 mapping ?

Thank you for helping.
