Beta InformationThis article discusses a Beta release of a Microsoft
product. The information in this article is provided as-is and is subject to
change without notice.
No formal product support is available from
Microsoft for this Beta product. For information about how to obtain support
for a Beta release, see the documentation that is included with the Beta
product files, or check the Web location where you downloaded the
release.SYMPTOMSAfter you unplug a USB audio device such as a microphone or
headphones on a Microsoft Windows Vista-based computer, there is no longer any
audio playback. For example, if you unplug USB headphones to hear the speakers,
there is no audio playback from the speakers. CAUSEThis problem occurs because the playback graph does not
detect that the USB audio device has been removed. Therefore, the playback
graph still tries to render audio for the device that has been removed.
When this occurs, you experience the problem that is mentioned in the "Symptoms" section.WORKAROUNDTo
work around this problem, stop and restart the media player or restart the
computer after every time that you unplug a USB audio device.
Note When you stop and restart the media player or restart the
computer, the audio project is reloaded. When the audio project is reloaded,
the playback graph is rebuilt to render audio for the audio device that is
currently plugged in.STATUSMicrosoft has confirmed that this is a
problem in the Microsoft products that are listed in the "Applies to"
section.
Microsoft regularly releases software updates to address specific
bugs. If Microsoft releases a software update to resolve this bug, this article
will be updated with additional information.
