Well, I disabled the only device that is available in the BIOS. When I did that, one of the audio devices in Device Manager went away, but "HD Audio" is still there. I don't see any other device in the BIOS that is audio related. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of David Roach Sent: Saturday, January 12, 2008 1:35 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: DTM problem Hi Sam, Did you disable the HD Audio device in the BIOS? If so, it should not appear at all. If you disabled it using mmsys.cpl, then the driver will probably continue to appear, but will not create a useful endpoint.

I have a related question. My device is just a plain PCM capture (only) device over USB. When I disable the onboard audio device, "HD Audio" still appears in Device Manager. (The onboard audio, however is gone and the system tray indicates "No Audio Render Devices". It looks like "HD Audio" is a software driver that is always loaded regardless. Is this true? Does it interact with my device even if it just a plain 8k - 44k PCM capture device? I ask this because things (in DTM testing) seem to work much better when "HD Audio" is disabled. ****************** 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/ ****************** 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/
