The recording properties for the SoundMax audio system in this machine lists "microphone" as the only audio input source for recording and it appears to be so. I recognize that the T61/p has no line input, but on my other TPs and my desktop I can record "internally", i.e. record a sound source like an audio stream or audio CD into the little sound recorder app or into Nero Wave Editor. I can't figure out how to do this on my T61. Am I missing something?

35 views and no ideas?

There's been a discussion about this in other forums. The stereo mix was disabled probably on purpose by the influence from the RIAA to prevent recording from licensed sources like Internet radio channels. I did a few driver tweaking and it didn't work. Looks like Soundmax sealed stereo mix for good on the T61p.

We should keep this thread alive since I would like to find out about the solution to this problem.

no no, i think the driver messed it up. i dont think the riaa or any other organisation can force them to do so. also i think soundmax came from asia...

it worked for sure on the t60
unfortunatly it seems since several weeks it also disappeared in my system. but also i bought several weeks ago the t61.. so i am not sure anymore if it really ever worked on my t61... 99% sure...

that would be an outrage...

have you guys tried to de- and reinstall all the drivers ?(also kb888111)

?

de and reinstall the sound drivers including the HD audio driver from Microsoft gives the same result. Stereo mix is still disabled. Why is there so many things messed up with the T61/p?

I tried installing the sound driver for T60/p and it would not let me.

Here is part of the ADIHDAUD.INF file that involves the stereo mix option:

----------------------------------------------

As you can see, the stereo mix is purposefully disabled here. The ADIHDAUD.INF file is part of the sound driver that came from Lenovo.

If that's not on purpose then somebody tell me what is?

Thanks. That's a great piece of investigating. I parsed the ADIHDAUD.INF file for "disable". Here are the relevent sections:

So the obvious question is, will some judicious tweaking of the inf file restore the recording functionality?

You see this line:

HKR,AD1984\\Disable, OutR, 1, 01 ;; Disable Stereo Mix Capture Node

That line specifically disables the stereo mix option. To enable it, just do this:

HKR,AD1984\\Disable, OutR, 1, 00 ;; Disable Stereo Mix Capture Node

So now the stereo mix option shows up on the recording controls, but guess what? You still cannot record from stereo mix. Like I said before, it is sealed by SoundMAX for good. Now, whether this is a hardware or software restriction, I have no idea. My 2 cents say it's hardware.

There's a software workaround for this using Virtual Audio Cable. it installs a virtual audio device so that you can record what you hear just like stereo mix. The only problem with that is, it's way more complicated and more expensive. If you don't know VAC, just google it.

Think again!

thats just horrible....welcome 1984 !

I can attest to the fact the Virtual Audio Cable works. Thank you for the information. As you stated, it has a bit of a learning curve, but once you get it, it does exactly what it promises.

This thread should be made a Sticky ..... If audio capture has been permanently disabled then everyone should know this before purchase.

How are we supposed to use Lenovo ThinkPads now to edit family movies or watch "and listen" to TV with a USB external tuner?

I agree with eecon. I also wonder if other manufacturers have done this too. Do the new HP, Dells, Compaqs and Toshibas have this same "defect"?

Good question about other mfgs.

Please Administrator .... please consider making this thread a Sticky.

Thank you.

I'm confused..how does this effect us being able to watch and listen to tv with a usb tuner?

Totally Agree...This makes me furious!

The Video only will be displayed .... the audio stream is not mapped through the ThinkPad's audio card so no sound.

If you have a T60 or T61 working with any USB TV tuner using Windows XP or Vista (non-MMC versions), please share how you did this with everyone here.

Thanks.

oh no..this is not good...i just ordered a USB tuner online...what is the point if we can't listen to the tv? this is bad

That is why I'm lobbying our Admisinstrator to make this thread a STICKY to alert everyone of this tragedy regarding the newer laptops.

Hopefully a fix is in the works for my T61 ..... my 3 year old T42 does not have this kind of issue.

there must be some hack available for this

See Generalsu above about using Virtual Audio Cable, but this whole deal about the SoundMAX being factory crippled stinks.

I wonder if this would be a viable work around?

My guess the key here would be it's ability to over-ride the lock Lenovo is now apparently putting on their laptops ability to capture and/or play audio from external sources like USB TV Tuner devices or your own home video camera.

Anyone else care to chime in here?

Great! Buy a 2 grand notebook and have to spend another $135. Forgive the sarcasm.

Instead of work arounds, imo, this issue needs to be treated as a defect that needs to be brought to the attention of Lenovo support. If enough people complain about it, perhaps they'll provide a fix.

I'll soon be on it like a dog after a stick:

http://forum.thinkpads.com/viewtopic.php?t=53194

please keep all discussion regarding this issue in one thread so that if we do decide to make it a sticky then everything is compiled in one place.   another moderator locked your thread for this reason.

thanks for understanding.

Sorry about the duplicate post ... I will stick to this thread until I contact Lenovo.

Since I have a 4 year onsite warranty plus damage protection, maybe I'll just ask Lenovo to send someone to my home out here in the deep woods and let them pull their own hair out trying to get my T61's SoundMAX to capture audio while sitting next to my T42 (that works great with the same external USB TV tuner).

Stay tuned .... excuse the pun

As for calling the Tech Support in Atlanta, Georgia, forget about it. They have no idea what stereo mix is and will not even try to help you out. I think they are paid to keep their mouth shut about this issue. I don't think this issue is a defect, but rather a copyright implementation to prevent people from snatching protected audio sources like Internet radio, Youtube and so on. If you look way above this thread on my post about the INF file, you'll see that the stereo mix option was purposefully disabled by SoundMAX. Changing the values on the INF file will not work even though the stereo mix option does appear on the recording control.

As for whether this problem occurs on newer laptops and even desktops, I am not so sure, but according to other forums, Gateway MT6821 has stereo mix disabled and Windows Vista also has stereo mix disabled by default. I believe most newer laptops will not have stereo mix as a recording option.

I agree this should be a sticky for anyone considering a laptop purchase, especially if they work extensively with audio. Disabling stereo mix is just wrong since other people use the feature for capturing their own audio instead of copyrighted sources. When I got my new laptop, I was *****Expletives removed by Moderator***** off by this and realized somehow SoundMAX, Intel and RIAA cooperated by maliciously removing the stereo mix feature.

For now, the only workaround I see is the VAC, which in my opinion works far better than the stereo mix feature, but requires a bit of a learning curve and a $30 per license fee.
