vlc 1.1.5 audio output starving, playing silence every 10 sec. using directx audio on Windows with Intel and CPU power saving management

VlC 1.1.5 final is giving me problems on Windows XP. Every 10 seconds or so there is a "hickup" in the sound, reporting in debug mode as "playing silence".

Same problem exists with nightly builds in branch and trunk. By proces of elimination I was able to trace back to the following periods:

win32/branch-20101001-0202 is OK win32/branch-20101002-0201 and all later fail

win32/trunk-20100802-0002 is OK win32/trunk-20100803-0002 and all later fail

So could be a change from trunk around 2 aug. that was backported around 1 oct. Otherwise a change in build system around these days?

Workaround is to force win32 waveout.

Note that I cannot reproduce the problem on Windows 7. Using --no-video still has the problem and rules out video issues with directx.
