Here in the driver, we observed -- from the wave system the driver is getting very frequent PAUSE and almost immediate RUN command even if from the application we are not calling any multimedia API to cause wave system to do that. This is creating a great problem for us.
Hello Chinmay,some time ago I had a similar issue. After some debugging it turned out that it was caused by the driver verifier that was active on my machine. It seens that the verifier introduces a event queuing mechanism, it collects events for a while and fires them all at the same time some time later. This leads to a performance decline within the audio subsystem. If the state changes form RUN to PAUSE it means your driver is running out of data.
Hope it helps /Uwe ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
