Bruce,

Sorry to tell you that you will not be able to internally record the sound card's output in your computer. You need a recording source called "stereo mix", but Dell has locked it out of the sound card's driver. They have done this on all of the different laptop models that have the Sigmatel 92xx audio chip, as your XPS does. On some of the models there are hacks that can be performed to unlock the stereo mix, but none is known for your model.

The workaround solutions:

Get an external sound card that has the feature you want.

Connect your output jack to your input jack with a stereo cable and record the result.


" also noticed that the Microphone/Line in
SigmaTel High Definition Audio CODEC was not plugged in.
Could this be the problem and where do you find it?"

I'm not sure what you mean by not plugged in. As far as where to find it, the Sigmatel codec is the audio chip on the motherboard, and I believe it is soldered rather than plugged in.

Hello Jim,
 
I do not know why Dell placed a sound card in these computer, XPS 1330, that can not record internally! You say that I have the Sigmatel 92xx sound audio chip. When I enter the device manager mode I notice two devices are shown, Hight Definition Audio Device by Microsoft which has diver version and the SigmaTel High Definition Audio CODEC. They both seem to be working . But when I right click the speaker icon and choose recording, two choses seem to apear, Microphone/Line In - Not plugged in and Microphone Array - Working. Both choses are using the SigmaTel High Definition Audio CODEC?
 
Thanks for your suggestion to rectify the problem. I found at the Sound Blaster ( Creative Labs ) site an Sound Blaster Xtreme Express card that maybe what you are suggesting. After I place the card into the slot, I then by a stereo cable and place one end in the output jack and the other end in the input jack. Finally, I run the recording software ( Audacity ) and I should be able to  to record internally, correct.
 
This seems like an around about solution, unless there is some other way, but If this is only way to record internally I will try it.
 
Thanks alot,
 
Bruce

Bruce,

I meant this as 2 different workaround ideas when I wrote:

Get an external sound card that has the feature you want.

Connect your output jack to your input jack with a stereo cable and
record the result."

You can try to implement the 2nd idea without having to buy another sound card. Yes, it isn't very elegant.

The 1st suggestion, to buy an external sound card: I don't know about Vista but in XP and before the Soundblaster cards could all record internally. Originally the recording source was called "whatuhear", but they later dropped that and at least on my Soundblaster usb card they call it "wave/midi/cd" but it's the same thing. The X-Fi card you mention should have it, but I don't know for sure. By the way, Dell sells that card on this site for $65 the last time I checked:
X-Fi Extreme Audio express slot card

What happens when you install an external card or any kind of audio device, when you go into Audio Properties the driver for it is listed along with the Sigmatel driver. You select which one you want to use as the default device. When you select a Soundblaster card, then you see the Creative mixer panel instead of the Sigmatel panel. If the card is capable of internal recording then "wave/midi/cd" or whatever will show up there as an option.

"You say that I have the Sigmatel 92xx sound audio chip. When I enter the device manager mode I notice two devices are shown, Hight Definition Audio Device by Microsoft which has diver version and the SigmaTel High Definition Audio CODEC.

Both choses are using the SigmaTel High Definition Audio CODEC?"

The Sigmatel STAC 92xx HD is your audio chip, also called a 'codec' in this context. The chip does the basic analog-to-digital and digital-to-analog conversions. I'm not sure what the Microsoft device is.

"I do not know why Dell placed a sound card in these computer, XPS 1330, that can not record internally!"

The Sigmatel chip can record internally. Dell locks the feature away from the owner. With some of the laptop models, the user could download a Sigmatel driver from another computer maker's site (LG) and it would have 'stereo mix'. There was another set of models where we could send the owner to another site where some of the Dell Sigmatel driver files had been unlocked by some clever folks there. Users could download the files and use them to alter their Sigmatel driver.

Sorry but I don't know of any similar fix for your model. But it's Dell, not Sigmatel, that is the source of the problem.

You'd think with all the complaints about this problem Dell would have fixed this.
 
Perhaps you could repeat the Vista and XP links for those new to this thread?

WDaren, I'll paste in the LG driver solution here, and the inf file hack in the next post. I don't think I've ever put these all in one thread before.

Jim

================================================================
================================================================

There is an LG driver for the Sigmatel 92xx that has stereo mix. To get it follow this path:

For models with XP:

LG Service Site

1. Click on 'Device Driver'.
2. Select 'Notebook' from the dropdown list under 'Product'.
3. Select 'Windows XP' under 'Operating System'.
4. Type 'Sigmatel' into the subject box.
5. Click 'search'. The driver to choose is the 4,601K one labeled Ver 5.10.04866 XNOTE(LE50)
6. To download, click on the file name, "SigmaTel.zip".

(This driver is known to work on most of the XP Inspirons with the 92xx chip but reportedly not on the 640m/E1405 and XPS M1210. This solution was discovered by forum member dhkang002.)

LG Sigmatel driver for models with Vista (tip from definch20):

LG Service Site

1. Click on 'Device Driver'.
2. Select 'Notebook' from the dropdown list under 'Product'.
3. Select 'Windows XP' under 'Operating System' even though you have Vista.
4. Type 'Sigmatel' into the subject box.
5. Click 'search'. The driver to download is the Series V1 94,472 kb file.
6. To download, click on the file name, "SIGMATEL.zip".
7. Next, select 'Vista' under 'Operating System' and click 'search'.
8. Download the small file named 'Windows Vista Sound'.
9. Install the driver (94,472 kb file) and restart.
10. Install the small file (Windows Vista Sound).
11. Go to control panel and open Sound. On the recording tab, right click in the large box and click on show disabled devices. A stereo mix option should then appear. Click on the stereo mix and then click on set default at the bottom.

If you need to undo the installation, use 'rollback driver'.

There is a very long thread at notebookforums.com called "Hacking SigmaTel Drivers for E1705/9400, i need knowledgable helpers", started by Veazer. Another poster working with him, falerus, found that he could unlock a number of controls and features in the SigmaTel audio driver by modifying a certain inf file in the R122161 audio driver. Building on falerus's ideas, eddiep, cais, and EagleGT modified inf files for other Dell laptops that also use the SigmaTel 92xx audio chip and R122161 driver.

Following are the laptop models, links to the modified inf files, and instructions for completing the hack. (These are falerus's instructions that I have modified a bit.)

E1705/9400 and Precision M90:

1. Look at falerus's post (#62 on page 5 of the thread) for his link to a modified 92XXM2-3.ini file. The link is right under the words "Attached Files". You will need to register to get it, then download and unzip it.

falerus inf file for E1705

2. Uninstall your SigmaTel driver through Add/Remove programs and download the Dell R122161 SigmaTel driver for XP. (The R122161 is the particular driver that was hacked. Windows Vista users should also use it.)

R122161 driver

3. Run the file. It will unpack the files to the location you specify and then start to install the driver. Cancel the InstallShield installation.
4. Go to the folder where the files were unpacked and browse to the "WDM" folder (C:\Dell\drivers\R122161\WDM).
5. Copy the modified 92XXM2-3.ini into that WDM folder, overwriting the existing one.
6. Go back up one folder to "R122161" (C:\Dell\drivers\R122161).
7. Double click and run Setup.exe. (You might want to turn off your antivirus program first.) The new installation puts a full featured SigmaTel audio control panel in the Windows Control Panel.
8. Restart
9. To enable Stereo Mix, go to Control Panel/Sounds, open the record tab, right click to display disabled devices then right click the Stereo Mix entry and enable it.



E1505/6400:

1. Look at eddiep's post (#235 on page 16 of the thread) for his link to the modified 92XXM2-5.ini file. You will need to register to get it, then download and unzip it.

eddiep's inf file for E1505

2. Follow the instructions for the E1705 above starting with step 2. In step 5 copy the modified 92XXM2-5.ini into the WDM folder, overwriting the existing one.


E1405/640m:

1. Look at falerus's post (#290 on page 20 of the thread) for his link to the modified 92XXM2-1.ini file. You will need to register to get it, then download and unzip it.

cais inf file for E1405 as modified by falerus

2. Follow the instructions for the E1705 above starting with step 2. In step 5 copy the modified 92XXM2-1.ini into the WDM folder, overwriting the existing one.


Latitude D620 and D820:

1. Look at EagleGT's post (#306 on page 21 of the thread) for his link to the modified 92XXM2-2.ini file. You will need to register to get it, then download and unzip it.

EagleGT inf file for D620

2. Follow the instructions for the E1705 above starting with step 2. In step 5 copy the modified 92XXM2-2.ini into the WDM folder, overwriting the existing one.


Other Models:

The above inf files, 92XXM2-1 -2 -3 & -5, are the only ones that have been modified so far. One or more of these might apply to a model of computer other than the ones listed above. For example, someone reported that the hack worked on a M1710, but I wasn't sure which modified inf file he used; I think the -3 one for the 1705. Cais gives some instructions for figuring out which inf file is used in post #292 on page 20 of the "Hacking SigmaTel Drivers" thread.

The following models are the rest of the Dell's that are compatible with the R122161 driver. If you have one of these models it is worthwhile to try out the different modified inf files in step 5 of the above instructions and see if one of them works for you.

B120, 1300/B130, M140/630m, D420, D520, 120L, M65, XPS M1210 & M1710 & M2010

These have the SigmaTel 92xx HD audio chip. The hack will not work on any model with the SigmaTel STAC 97xx chip.

Post #404 on page 27 by hunnja gives some complicated instructions for the Inspiron 1501 model.
The 1501 instructions reportedly also work for the Inspiron E1405 model.

It's a crime that you guys have had to spend so many hours to provide a basic feature that should have been built-in.

" I have a Dell XPS 210"

I'm not familiar with that model; could it be an XPS M1210? If it is then just download and install the latest Sigmatel R171789 audio driver from your driver downloads page. It was released in December and it has stereo mix.

Jim

Edit: I found an XPS 210 desktop computer; if that is your model then don't use the driver I named above, because it is for laptops.

pinkluva,

This is the Laptop Audio board. To get help for your model use the 'Navigation' section on the left of this page to go to the Desktop Audio board.

Because we don't deal with desktops on this board, I don't know the specific solution for your specific model. The generic solution for the desktops is to just get an inexpensive Soundblaster pci card and put it into one of the pci slots inside the computer case. That would be a popular solution for us laptoppers too if one could use a pci card in a laptop (one can't).
