我的独家模式wasapi代码有什么问题？ [英] what's wrong with my exclusive mode wasapi code...?
问题描述
我在HP Pavilion Vista Business 32位上有一张RealTek卡。
I've got some kinda RealTek card on an HP Pavilion Vista Business 32 bit.
另一台电脑：惠普Pavilion Windows7 64位。 相同的"内置于主板声卡"我想。
Another pc: HP Pavilion Windows7 64 bit. Same "built into mobo soundcard" i think.
在Vista上，我已经更新到最新的声卡驱动程序。
On Vista, I've updated to latest soundcard driver.
以下是我使用的代码我改编自msdn独占流示例。
Below is the code I'm using that I adapted from msdn exclusive stream example.
到目前为止，我只测试了Open（）和Shut（）音频功能。
So far I'm only testing out the Open() and Shut() audio funcs.
我终于得到了waveformatex params。
I finally got my waveformatex params right.
（愚蠢的声卡的OEM表示它会做32位48KHz，但是IsFormat ......只说
(Stupid soundcard's OEM says it'll do 32 bit 48KHz, but IsFormat... only says
CD音频规格好的。）
CD audio specs are ok.)
所以，如果有人可以帮助我...？
So if anybody could help me out here...?
提前致谢：）

推荐答案
RATS，忘了提及它死于_aud-> Initialize（）
RATS, forgot to mention, that it dies at _aud->Initialize()
我在其他一些帖子中看到，如果驱动程序不进行事件驱动，则需要使用基于定时器的缓冲区写入。
I saw on some other thread, that timer based buffer writing needs to be used if driver won't do event driven.
所以我_aud-> Release（）并获得另一个尝试使用0而不是事件标志初始化（）。
So I _aud->Release() and get another and try Initialize() with 0 instead of the event flag.
STILL不起作用。
STILL doesn't work.
我还应该解释一下，我通常有自己的启动代码，但不适用于这个应用程序，因为它使用浮动（而dang wasapi COM的东西让我需要crt启动也是。
I should also explain that I usually have my own startup code, but not for this app cuz it uses floats (and the dang wasapi COM stuff makes me need crt startup too).
所以crtstartup => WinMain => AppBoot => Go - 执行AudO类的Open（）和Shut（）。
So crtstartup=>WinMain=>AppBoot=>Go - which does Open() and Shut() of AudO class.
好的，sooooooo omebody he'p me pleeeeeeeeease !!
Ok, soooooooomebody he'p me, pleeeeeeeeease !!
