Here's some more interesting info, regarding getting more recording options:

Does anyone know of an ASIO driver for our Dell e1705's? I ask because when I record using my Firebox external soundcard, it uses ASIO drivers, and if there were ASIO drivers for my Laptop also, then I could playback using my laptop speakers instead of having to plug other speakers into the Firebox.

These work well for me --> http://www.asio4all.com/

well last night i managed to get this:


it allows you to change b/n mic and line in.

One problem though is it gives an error every time you start the sigmatel app because our laptops dont have a "rear speakers" port. I'll look into this today, and I guess I'll also try seeing if the mic port can be changed to stereo out.

Nice work. I'm wondering now if the dual outs will be possible since the onboard speaker are technically another output. If we are using the headphone out and the onboard speakers, maybe both of are outputs are already 'used up' ?? something to consider. Ideally the driver would let you use any 2 at the same time but they might not have thought of it.

Here's a useless but interesting trick, change Config_OEM entry in STacGUI from 0 to 1 and it will change from a SigmaTel control panel to a "Sound Reality" control panel. No effect on features, but it looks better than the fugly sigmatel logo.

A really insteresting project. Would be great to have all the features provided by the chip. My Precision M90 should have the same chipset. I already managed to get those extra options in the control panel.
@falerus: how did you get the port configuration?

I've been doing all my hacking in the ini files because it enables a lot more than just registry hacking, and all the registry entries are there too. Also, it's very easy to distribute, I just have to put up a copy of the ini file, and people just have to replace that one file and run the installer (I'm gonna do that in a bit, it'll have a working equalizer along with all the options enabled to the best of my ability [port config, advanced, dolby, etc.])

@Fusel
I looked at all the ini files provided by Dell and I think two of them had port config enabled so I just added that bit to my frankenstein ini file.
One minor problem though is that since you have a M90, it might be using a different ini file than the e1705 (Dell provides 7 different ini files). I do speculate that it's the same file though. I guess we'll find out.

Ok i attached a zip of the ini file.

What it has:
1. All the config screens as seen in Veazer's screenshots post.
2. Additional "Jack Setup" screen as seen in my screenshot (but now without the rear speakers port and thus no more annoying error message). This setup screen doesn't seem to do anything.
3. Equalizer that works
4. Input monitor: You can listen to whatever you have plugged into "Line In". I don't know if the original driver does this.

Instructions:
0. Uninstall your sigmatel drivers through add/remove programs if you want to be safe. Don't if you want to be daring.
1. Download the newest sigmatel drivers from Dell
2. Run the file. It will unpack the files to the location you specify, then it will proceed to install the driver. Cancel the driver install.
3. Go over to the folder where it was all unpacked and browse to the "WDM" folder. For example I have "C:\DELL\drivers\R122161\WDM"
4. Copy 92XXM2-3.ini into that folder, overwriting the existing one.
5. Go back up one folder to "R122161". For example "C:\DELL\drivers\R122161"
6. Run setup.exe. Certain antivirus progs may slow the install down alot, so it may be a good idea to temporarily stop protection (KIS 6.0 makes the install about 5 times longer for me)
7. Go mess around with the SigmaTel control panel applet

Disclaimer: I will not be held responsible if the above instructions harm your laptop in any way. kthx

Please post your results of doing the above.

I don't know how much more hacking is possible, and I don't know if Veazer has made any more discoveries. In any case, thanks Veazer for all the work you've done.

i just want my mic port to output sound. how do i do that?

thats good for airport trips. any program to do this istead of uninstal,ling drivers and reinstalling?

Currently veazer has found a way to do that at the cost of disabling the onboard speakers. So far there is no way around that (i think).

Is there a specific reason why you need to use the mic jack as an output? If it's because you want two outputs then maybe you could just buy a $1 splitter?

Cool thread, very interesting. Keep up the good work!

Nice!
I'll test it once I get to my dorm.

Wauw! Amazing work guys! +rep for you!

Maybe this will solve some of our crackling and popping problems also?!

haha I was messing around and I managed to get both the laptop speakers and the audio jack to output sound at the same time. Fake 4.1 surround sound anyone (using a set of desktop speakers)?

I tried the driver. It works perfectly!

The only suggestion is DON'T use Intel installer.

Go to Device Manager, right click Sigmatel HD Audio Codec, and select upgrade driver.

Intel installer gave me "unknown error".
