Here's a tip:
If you provide *specific steps* to reproduce the bug you're describing, using one of the sample drivers for example, you get more chances that someone else can confirm the problem and/or that someone at MS addresses your issue.

Hi,
I never have been able been able to get an answer to this question.
I don't know what else to say. I wish I could be more help.
I wish that some one at MS would either disprove what I am saying (tell me what I am doing wrong), or give us an explanation about why such behaiour happens, or just admit that it is a known flaw.
As of now, I have heard nothing.

Hello,
I noticed your post on the WDM Audio Dev list server from *way* back, and wondered if you ever got a reply from Microsoft?
I have noticed that after going though a repeated pause/restart condition multiple times, WDM eventually stops sending audio (it still sends buffers, but they are all silence). This happens with pretty much every driver I have tested (including the AC97 sample driver), so I am pretty sure this is a problem with WDM and not the driver. Has anyone else seen this problem or
have a fix?
Thank you,
David
