Windows 7 DirectSound Output Can Become Incapable of Playing Audio

Uninstalling and reinstalling inbox audio driver repeatedly on Windows 7 or Windows Vista might not be the best thing to do, as Microsoft has warned that users could leave their platforms incapable of playing audio. The Redmond company does not specify the exact number uninstalls/reinstalls needed for some DirectSound output to be rendered unable to play audio, but apparently, just several such actions are sufficient.

Here is the scenario described by the software giant: “You use software to render/play audio via the DirectSound API (for example: DDK tool Graph Edit). On Vista or Windows 7, via a driver testing tool (or manually) you uninstall and then reinstall audio drivers such as “High Definition Audio Device” (HDAudio) several times. You attempt to render/play the audio stream again to a non-default DirectSound device (for example – DirectSound:Speakers as opposed to Default DirectSound device).”

Provided that users managed to reproduce the situation exemplified above, Microsoft indicates that no audio will be produced as a result of the stream leveraging a non-default DirectSound device for rendering. In addition, Vista and Windows 7 customers will receive the following error message: “These filters cannot agree on a connection. Verify type compatibility of input pin and output pin. Cannot play back the audio stream: no audio hardware is available, or the hardware is not responding. (Return code:0×80040256).” Read More»

Get EAX sound effects working in Vista

The pain…

If you’ve invested your hard earned cash on a Creative X-FI sound card and a copy of Vista, you may be feeling a bit underwhelmed right now. Some of your games may be sounding a bit flat and lifeless and you’ll have no doubt felt that sinking feeling when you edit the sound settings in your new game only to find that you can’t enable some of the fancy options. There is a good reason for this and you probably will have been told at great length about it by one of the many passengers on the anti-Microsoft bandwagon.

The Science…

If you’re an experienced PC gamer you’ll no doubt be aware of DirectX and the various functions that make up the DirectX standard, such as DirectDraw, Direct3d and DirectSound and DirectSound3D. You will probably be aware of the hype surrounding Direct3d already, given that it has now reached version 10, but that’s a story for another day. DirectSound is what we are interested in here and it is sadly missing in Vista. XP and DirectX9 featured a “Hardware Abstraction Layer” which was a piece of software that allowed Windows to talk directly to a soundcard such as the X-FI to provide hardware mixing and 3d effects for your games. Without this layer any sound you hear will be mixed using software, rendering much of your shiny new soundcard useless. Read More»
