AC3 Default?

[canthackit]

Hi
I about 6 months ago updated my DD Amp, and since the inclusion of the AC3 default and AC3 Downmix options i've never had any problems with either Amp.

A few days ago i run the roomEQ which i've done many before without any faults, but sadly this time i'm getting what i can only describe as loud cracking type noise coming from the front speakers particularly when changing from an Analog channel to a DD channel, i've tried everything a man can try, rewiring my speakers, checking my HDMI inputs/Outputs, and so on and so on.

Then i see the AC3 Default option, thought sod it and turned off both options whereas i've ever enabled the AC£ Defailt option, well that solved the problem.

So why after all this time should this problem start happen?
and what i thought were the correct settings now appear to be wrong settings.

Phew:o10:so can someone tell me what is the correct setting using an Amp? and what do the AC3 options mean then?

sorry for the long post but i've got to get this sorted properly.

Thanks & Regards: canthackit

Dolby Digital, or AC-3.

the settings tell the DM800 what to do with this audio? send it to the audio cinch, spdif coax or optical, hdmi.
Process the audio in the DM800 or pass it raw to the external amplifier.

OK thanks mate...........

but now i find out after that long post it wasn't the problem, the problem appears to be certain channels wern't the correct ones as on $$$ HD as you know there's quite a few different options on each channel i had lot of wrong channels, also on sirius and thor it's took me bloody hours but i think i've sorted it.:champion-018:

then again i thought that last time:iamwithstupid:

Nope spoke to soon again:biggrinjester:

i did manage to eradicate the problem by enabaling both AC3 default and AC£ downmix, problem there though is i can only achieve Pro-Logic II at best no DD.

So i've been in touch with GenServe who do the repairs for Onkyo it's going back to them today:respect-050:

thanks for your help anyways:respect-020:
