Edterbak,

Had a quick scan of the avsforum page. To be honest I try to avoid that forum as the threads get far too long and my attention span is too short.

But I still think your problem (from what you have said) is that your DTS5.1 is being sent at 48K (i.e. totally corrupted) when it should be at 44.1K.

There is no question of SPDIF not working at 44.1 because common or garden CD playback from bog standard CD players are at 44.1K.

Maybe others on the AVSforum are also trying to go to the amp via a PC type soundcard and are also having 48K problems.

Does you amp have an ordinary coax phono or TOSLINK SPDIF in? If so try a straight link from PC to amp via that. That will rule out HDMI reciever issues on your amp.

You can also buy adaptors (or you could easily make one if you have an old phono socket and soldering iron) which will alllow to connect your SPDIF header on your MB to a phono socket mounted on a PC slot bracket so you can test amp without HDMI lead complication.

I have checked out your MB. It uses a realtek ALC662 audio chipset. So like my MB audio (ALC889) it cannot auto switch between 44.1K and 48K. Especially with the newest realtek drivers which auto resample evrything to 48K. Maybe you can try to get hold of some old Realtek drivers which at least allowed you to switch between 44.1 and 48K via the system tray applet.

So even though you are taking spdif from your on board sound card and routing it through your HDMI lead you are still at the mercy of the dreaded realtek drivers.

Only thing I can suggest is try to get hold of old realtek drivers so that you can at least test 44.1K DTS etc or get the cheap £6 soundcard that Jameson recommends.
