Can't see Stereo Mix on Dell Inspiron 7520
Hello
I've googled and read a lot of forum posts about this topic but I still can't figure it out.
I have a new Dell Inspiron 7520 and I want to use the Stereo Mix feature so I can record audio coming out of my Conexant SmartAudio HD soundcard. I right click on the speaker icon in the system tray, click Recording devices and then right click the white space to Show Disabled and Show Disconnected Devices however still Stereo Mix won't show up.
I have installed Audacity but Stereo Mix does not show up under the Input or Output devices there either.
I've tried downloading the latest Conexant Driver from the Dell Drivers webpage and also tried installing the latest RealTek Driver but no luck with either. Some say StereoMix may not be available at the hardware level but I'm not sure.
From another forum I tried the following with the Conexant driver but either I wasn't doing it right or it didn't work either...
I opened the driver .inf file, it was called oem2.inf and these three lines were commented (they each had a semi-colon before them). I uncommented the lines:
HKR,%EPattributePath%\EpSettings\StereoMixEnable,Enable,1,01
HKR,%EPattributePath%\EpSettings\StereoMixEnable,MixAssocSeq,1,E0,E0
HKR,%EPattributePath%\EpSettings\StereoMixEnable,MuteGainSettings,1,00,00
I then went into device manager and re-installed the Conexant driver by browsing to the location of the .inf file I just edited (by removing the semi-colon comments). But I then got the error message: "Windows found driver software for your device but encountered an error while attempting to install it - Conexant Audio HD - The System cannot find the file specified." Right before that I noticed it says the driver is not signed which might be a problem as I have 64-bit Win 7 Home Premium. To try and get around that I opened an elevated command prompt and typed: bcdedit /set nointegritychecks ON to try and by-pass the requirement that drivers be digitally signed in case that was the problem but it didn't help.
I downloaded Speccy and here are my system details:
OS: Win 7 Home Premium 64-bit SP1
CPU: Intel Core i7 3612QM @ 2.10GHz
Motherboard: Dell Inc. 0PXH02 (U3E1)
Audio: High Definition Audio Device
Any help greatly appreciated, maybe someone knows of drivers that will work with my chipset/motherboard and give me Stereo Mix?
Cheers.
