Vice 2.1 audio skipping

Is it normal that every so often in Vice, you can hear audio hiccups/skipping, presumably due to the refresh-rate not being emulated solidly?

I normally use my real C64, but on the odd occasion that I fire up Vice to quickly check out downloaded stuff from csdb, I find it really annoying, especially because it's mainly music that I'm interested in.

I just wondered whether this was considered normal behaviour for listening to and even making music with Vice?

I have an RME Fireface800 soundcard, 3.6 ghz Intel quad core PC with 4 gigs ddr3 ram running Vista64.

Cheeeeeeeers

Check your soundcard buffers. Normally, that's the fault. Firewire on PC is not stable either, that's why many composers convert to MAC. Especially after Vista came out. Or I'd prefer a PCI soundcard, and XP on PC.

I use loads and loads of tracks and effects in Reaper and Cubase with no problem.
The RME drivers are solid. This is one of the reasons that this soundcard is used by professionals.
I especially chose my motherboard for the TI chip on it for my soundcard.

I've heard of alot of troubles with these soundcards on PC, especially. You can still use this soundcard on the MAC, as the professionals do. It behaves differently in Cubase, since it's using the ASIO drivers.

Problems with the Fireface 800 were people without a TI chip on their motherboard.
I've been using it for 2 years with no problems whatsoever. It's been solid as a rock.
So... are you saying that nobody else gets these hiccups when using Vice?

I don't get any hiccups.

I'm 100% sure you've set a very low latency buffer setting in your soundcard software. That works fine in Cubase, depending on how many tracks of audio you use. But for other Windows GUI's this will not work. Try setting a higher buffer.

I just turned on WMM driver in settings->sound settngs and it seems to be totally stable now.
Why didn't I try that already!? *facepalm*.

Yeah, it is usually a user's fault. That's some of the cases I got bored working in the music business. :P

User fault?
Surely I should be able to use the Direct X driver?

FYI, when I use the Direct X driver, the audio sounds perfectly fine whether I use a souncard latency of 48 or 1024, so it doesn't seem to be a soundcard latency issue, but it seems to be Vice that is actually skipping frames. The audio isn't glitching, but the Vice framerate is.
This doesn't happen when using the WMM driver though.

You didn't use the WMM driver, hence a user's fault.
