Windows 7: VoIP Apps Can Hang on Windows 7

VoIP Apps Can Hang on Windows 7

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 hands, 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.”
