Wonder if AE needs to be made to work better with realtek? that is what my system has for audio and probably allot of others with small scale systems.

Can't use hdmi; My speaker system is optical. My TV will only output stereo through it's optical out. So it's directly connected from the pc to the connection at the back of the sub.
(that aside, I'm happy with what I have. And as I said earlier I seriously doubt the human ear can tell the difference)
Can't use any other drivers as the sound chip is realtek. Graphics card drivers therefore have nothing to do with it.
You said "do not misunderstand bla bla" but let me give you something honest: and from what you just said as well "I buy a new set up every year bla bla" with that kind of thing, you come across as being a douche.
Apart from that though you seem to be helping people as best as you can despite that. So thanks.

c'mon guys, the forum is no place to exchange insults :-)
Further testing shows that even using HDMI - WASAPI I'm having the same choppyness issue when playing PAL 25 fps progressive (constant discontinuity errors). So it's not the Realtek driver since for HDMI audio I use the AMD Catalyst one. I have an AMD E-450 based htpc.
Logically that leaves 2 potential causes:
1. The CPU: the (relatively slow) CPU could be causing the issue, because as I mentioned above, everything's good on my Core i7 / nVidia, same test videos, and by the way this one has Realtek drivers (SPDIF - WASAPI)... It's improbable, because I'm experiencing this only at 25 fps, and not at 50 fps nor for HD material! It's very odd that this occurs at the low-end of the spectrum, which should be the easiest on CPU/GPU (i.e. SD/progressive material).
2. The GPU: perhaps a Catalyst video setting is messing with the timing (since my Core i7 has n nVidia GT240 on board, and that works ok). I'm using the recommended settings of "Enforce Smooth Video Playback" ON and Automatic Deinterlacing OFF. But I'll play with these and report back later on the results.

@fat-tony: I'll check the CPU utilisation tonight. I'm using the AE nightly, so technically from that perspective I assume you've got the same AE code. Perhaps can I ask you (since you seem to have a Fusion E450 as well) to try turning off deinterlacing and play a PAL DVD (and use WASAPI of course). On my machine, the fps shown is dancing up and down around 25, but does not stay constant. The video becomes unwatchable, since I've also sync playback to display set to on. Even set to off, it doesn't become a lot better.

Eureka, I found it! It was a Catalyst setting indeed, "Pulldown detection" was checked. I unchecked it and now audio playback through WASAPI doesn't cause choppy playback anymore.
Thanks fat-tony, for the help you provided by running these tests.

hi all...
i have an issue with just installed nightly and audioengine..

any thoughts?

Can't be CPU can it? I don't get choppyness through headphones using the analogue speaker jack in the back of the PC. Only through spdif. My GPU is Nvidia.
Considering the fact that Eden has no video choppiness issues, it has to be AE at root. Unfortunately with Eden the audio blips when a file is played and then after a bit with no sounds the connection goes to sleep or whatever it does. This is why I'm using the AE builds.
To steefen: thought pass through connections where for the sound to go to the receiver and not play on the TV? Don't know much about that, but my TV only sends stereo though its passthrough (so I can't use it for serious sound) but when I tried it with my xbox; I only got sound out of the sound system and not the TV.
