Windows 7: Windows 7 Ult.x64 w/ Realtek ALC665 StereoMix NOT WORKING!

Windows 7 Ult.x64 w/ Realtek ALC665 StereoMix NOT WORKING!

I have updated realtek driver to v6.0.1.6662 6/2012, however updates do not seem to change anything. My lappy has an internal mic, but also an external mic plug (which can be re-purposed, but is originally a mic plug).

The internal mic is connected to ATAPI internal port, that much is clear, however the External Mic (which should be Stereo Mix as I don't see any other recording devices besides the two) show NO port in the properties. See attached image. This precludes me from using an external Mic in the Mic Jack, and I am forced to use the internal Mic which sucks for anything but Skype.

There is some trivial advice going around the web on this issue, I am just going to cover it here, to prevent repetition.

1. No recording device has "listen to" enabled
2. None of the jacks have been re-purposed
3. None of the recording devices are enabled as sound/communication devices (this repurposes them)
4. and yes, the Mics (both) are unmuted (how trivial is that?)
5. It doesn't matter which Mic I set as 'default recording device' the stereo mix never record, only the internal mic
6. enabled/set as default/recording levels, none of that is the problem, tested
7. There is a conspiracy theory going around that RIAA 'forced' Realtek to cripple StereoMix so that you can't record what you play on your computer, but that sounds too crazy (as all conspiracies do)

Finally, to underline my problem, it is not about the Stereo mix, per se, but using it (or anything else, but what?) to connect an external pro Mic (with computer plug, not XLR) to the mic jack on my lappy.

It shouldn't matter which laptop is in question, since all realtek drivers of ALC665 seem to have the same problem, but it's Alienware M11X R3.

In most cases the PC Vendor's drivers are the preferred drivers. Many times the drivers are customized by the PC vendor for their hardware. I don't know about Alienware, but other Dell's, such as the XPS or Inspiron desktop lines need Dell sound drivers.

The rumor is just that, a rumor and not substantiated as many PC's with RealTek, including two desktops and one laptop that I have with RealTek all have the Stereo Mix (System Mixer).

On some Dell's, as they were delivered the Stereo Mix was disabled. But, all that had to be done was go into the Sound Panel/Recording section. RIGHT click on a blank space in that panel and then click to show disabled and disconnected devices. If Stereo Mix is there it will now be displayed and you can enable it and make it the default recording device.

If the Dell supplied driver does not have Stereo Mix, you can try the generic RealTek drivers however they have a notice to get the drivers from the PC vendor.

You could post this on the special Alienware forum section on the Dell Community and see if someone there has an answer. Dell Alienware Club

Hi, thanks, that's a good advice, generally, but not in this case. I was referring to the Realtek codec above, ALC665 which is the relevant information.

Of course I tried EVERY SINGLE driver available, be it from Dell, Alienware, Realtek or otherwise. Actually even the Realtek-direct drivers recognize Alienware and install a special set of drivers and control panels which say "Alienware Audio" everywhere.

So, thank for the effort, but no cigar

And, yes, I did post the question on a few other forums. Btw, Alienware was bought by dell, but is not a division of dell, it is a separate company (not like their XPS line, Alienware are not a line of Dell, but a completely separate company). FWIW

Alienware may still be a "separate company" but they have been folded into Dell web sites, both the Dell community and Dell support. If I go to Dell support to look for drivers for any Dell line, the Alienware is included. If I go to the Dell sales site I can buy an Alienware there, the same as other Dell PC's.

I used to do a lot of user support on the Dell forums (did it for 10 years and over 38,000 posts) so I'm well familiar with Dell and Dell products. We used to get a lot of Alienware hardware and software questions on the Dell forums but the forum moderator would always point them to the special Alienware owners forum section.

As far as the specific model PC. I'm not up on the laptops as most of my support was in the desktop and software areas, but I know there were a couple of Dell models that never had the System Mixer (Stereo Mix) support and users with desktops with "must have" were installing separate sound cards to get that. Back in the XP days there was a registry hack that would enable that, but as Vista/Windows 7/Win 8 handle some sound functions differently from what I remember that hack didn't work on non XP systems.

You are right on the site. Alienware's was made to forward to Dell's some time ago, but it didn't use to be that way.

This model definitely had Stereo Mix and it used to work. I've had the laptop for almost two years, and I seem to recall I tested it with an external mic in the beginning.

Maybe it is some kind of conspiracy and this feature was removed in newer drivers, while it existed in the previous incarnations? I am not sure if I can downgrade a driver without re-installing the entire system.

If you have an older driver, go to the Device Manager, RIGHT click on the sound entry and then LEFT click "uninstall". Check the box to also uninstall the drivers. Then restart the PC and install the older driver. If you are lucky it will work.

Yes, that is the most trivial method (I'm a computer engineer), of course, but it doesn't work.. It still keeps some files somewhere and the installation succeeds but the same files are there, not overwritten. Might try with Revo to see if that happens, otherwise clean install would be the only method.

What happens when you plug an external mic in? And no it will not be StereoMix, that is something else. Possible nothing will show up for the external mic until one is plugged in. My keyboard is the same, it has audio output via USB but its not available until I plug headphones or a mic into it.

I see RealTek listed in my Revo Pro. I've never tried it but worth a try.

BTW, I'm a retired computer hardware tech and a LAN/WAN Network and Hardware Help Desk Manager.

If it worked at one time with the original factory load, then the reinstall backto the factory disc image is an option.
