DShow audio takes a VERY LONG time to start

[Videogamer555]

DShow audio and video means audio and video from a hardware device rather than a media file. And t doesn't matter if streaming out, or directly playing it, or converting it. Any access to DShow audio takes up to a minute to start! Meanwhile DShow video starts almost instantly! If doing audio and video, then the video does wait for the audio, in order to remain in synch. But why is the DShow AUDIO taking so much time to start?

Please help.

When I initialize the device in GraphEdit it is instant.

Hopefully someone can give us some guidance

Hi, thank you for your reply. I would like to ask if this bug has a tracking id so I can keep watch on it.

Thank you very much

Search the trac with dshow keyword.

I know it's a long time ago, but has this bug been fixed yet?
