  • A few posters have been able to get it by doing a small hack. Unfortunately I don't remember which models, but they had Conexant audio. To try the solution that worked for them go to this forum:

    Go to the 1st page of that thread and scroll way down to the 15th post. The poster's name is AcrUsr and he found the hack. Keep reading that thread for more details from AcrUsr and screen shots.

    After you reboot, you may need to enable the stereo mix device. To do so,  do the "Show Disabled Devices"  thing again. If stereo mix  says it is disabled, right-click on it and left-click on Enable.

  • Hello Jimco, thank you very much for the link. I did the all things like he have mentioned in the thread, but when I try to re install the driver it says "Windows encountered a problem installing the driver software for your device" and the system cannot find the file specified. can you help me to solve this problem?

  • Thanks Jimco, I have done all the things as he mentioned in the thread, but still I get the same error, I doubt  if I'm editing the right .inf file. it's in C:\Program Files\CONEXANT\CNXT_AUDIO_HDA. the name of the inf file is oem1.inf. is it the right .inf file which I should edit?


  • I don't have anything to add to what was said already by AcrUsr and SeanieOS.

    > SeanieOS said the file is in the C:\Windows\System32 folder

    > AcrUsr said to find it "use the Win7 in file search and search for the string "EpSettings\StereoMixEnable,Enable" (without quotation marks)".

    > SeanieOS said he searched for "EpSettings\StereoMixEnable".

    In message 20 of AcrUsr's thread, he has a link to a picure of how the files look on the screen.  The link is named Inf-File-Edit.jpg 389 KB.

    I probably know less about this than you do because I have a different model laptop that does not use Conexant audio. The person you should ask is SeanieOS if you have difficulty with the directions. However be aware that you probably have a different version of the Conexant audio driver than he has, so what worked for him might be slightly different from what will work for you. But at the least I would expect that your file would be in the System 32 folder like his was.
