I am trying to help a friend with an audio problem. Basically, XP Home loaded its default native drivers for the onboard audio of the e-machine, model T1120. However, we are still not getting any audo output. Within Device Manager, Intel 82801 AA AC'97 Audio Controller shows along with other entries. Whenever I double click on an mp3 or wav, I get the following error message: Windows Media Player: wmplayer.exe - Entry Point Not Found. The procedure entry point GetIUMS could not be located in the dynamic link library msdart.dll. When I click OK, this error message mysteriously disappers as mysteriously as it appears. But, Media Player opens up with an error message. Cannot play back the audio stream. No audio hardware is available, or the hardware is not responding. I am not sure where I remember seeing the message, but, I also get No Mixer Devices Available.
With respect to attempted troubleshooting, I checked the BIOS to make sure the onboard audio is enabled. Also, I downloaded the audio driver for the model of my emachine and updated the audio driver. To my surprise, the Intel 82801AA AC'97 Audio Controller changed its name to SoundMax Integrated Digital Audio.
At this point, I am not sure if I am even using the right driver update. Any help on this post will be appreciated.
