DShow audio takes a VERY LONG time to start
Posted: 25 Feb 2013 11:28
by 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.
