微軟在官網上發出通知，針對使用最新一代的Windows7用戶，他們可能會遇到運行時VoIP（IP電話）時掛掉的問題。據微軟公司說，音頻播放和捕獲類軟件確實會在Win7系統下掛掉，這類軟件主要以VoIP類軟件為代表。
“在音頻設備反應遲緩的情況下，Win7系統下的WaveOut API接口有時不能正確地處理音頻樣本”，微軟解釋說。 “
VoIP應用程序一旦在Windows 7掛起，目前唯一的解決辦法就是重啟這個應用程序，微軟表示這是一個錯誤，並且，微軟會盡快發布一個熱修復補丁（HotFix）。
Windows 7的所有版本都可能受到此問題影響，微軟沒有說明何時會提供修補程序，但請大家關注Windows7之家，一旦有更新我們會立即通知大家。

VoIP Apps Can Hang on Windows 7
Microsoft is working on producing a resolve
Microsoft has informed users of the latest iteration of its Windows client that they might come across issues when running VoIP (Voice over Internet Protocol) applications on their computers. According to the Redmond company, audio playback and capture applications can hang when used in combination with Windows 7. The software giant revealed that applications performing audio playback and audio capture simultaneously were typically VoIP software. Windows 7 customers running VoIP solutions can often experience hangs, Microsoft stated.
“WaveOut API on Windows 7 sometimes fails to process audio samples correctly when response of your audio device is slow,” the company explained. “There is a problem on how WaveOut API handles audio playback requests and audio capture requests submitted by your application.”
While the software giant has confirmed the issue and even identified the source of the problem, an update is not yet available to resolve the issue. At the same time, Microsoft is most likely not to release an update, but to allow affected customers to resolve the problems by applying a hotfix, rather than serving a refresh to all Windows 7 users.
For the time being, Windows 7 customers that have recognized the symptoms described in this article and that are impacted by this specific problem can turn to a very simple workaround, albeit the solution is only temporary and will need to be repeated in the eventuality that the Windows 7 VoIP applications hangs again. “Once a hang occurs, the only resolution at this point is to restart the application,” the company stated. “This is a bug. Microsoft is planning to release a hot fix.”
All editions of Windows 7 can potentially be affected by this issue. The Redmond company did not indicate when a hotfix would be offered, but keep your eyes on Softpedia, and we’ll provide an update once it happens.
