Bad audio stuttering in rendered files

I thought I remembered some discussion of this a while back, but can't find it...
Recently, the audio in my Sony Vegas Pro10 renders (to SD AVI files) started breaking up very badly. Terrible stuttering.
I'm only mixing/rendering 4 audio tracks.
Sometimes the problem gets cured if I render to 44.1K instead of 48K.
Also sometimes gets cured if I disable ALL audio FX (which had only consisted of a little bit of EQ on 2 tracks and compressors on 5 tracks).
Even tried rendering a WAV file using only 2 of the tracks -- same bad result.

I've also been trying rendering audio-only, to various formats of WAV file, and the problem persists. (resulting files are bad whether played back in Vegas or using Windows' own audio player.)
Audio for other purposes on my system - like playing audio from the web - works properly -- on VEGAS rendering is resulting in bad audio.
I've tried rebooting, too. No luck.
I'm quite baffled here...

Baffled here too even if it might be another/similar problem:

It seems that one of the last "updates" of Windows Media Player has made it totally unusable.
Really bad audio stuttering in most (??) videos no matter what Bps and no matter if i or p.
Did try to re-render with p/i and/or higher/lower Bps - but it did not change much - WMP still stutters the audio.

Before these updates WMP did stutter too - but not when I played the video from a copy on my NAS - but now it even stutters when playing from a NAS with a 2 seconds buffer.

VLC player plays the files perfectly and if I put such a rendered file onto the Vegas timeline also Vegas plays it perfectly in preview.

Work around here: I just set VLC player as default player for file types. I always used WMP before because VLC player did several lenghty disc accesses at every start up - but this luckily seems to have been cured in the very last update (2.1.1) so that it now starts immediately.
