STEREO MIX WORKS ON T61p....
After fiddle around with this for a while (I mean a long while-months), I finally get the stereo mix working on my T61p.
Machine: T61p, OS: Vista U SP1 with latest update
Sound card driver: analogDevices 184.108.40.20610
Tested with Audacity 1.3 Beta version
1. Modify Registry: (Please be careful in doing this as it can destroy your computer.)
a. run regedit, then click on HKEY_LOCAL_MACHINE
b. then do a Find for all AD1984
c. Go into Disable folder in the left, then change both MicBP and OutR to 00 (not disable)
d. You should find at least 2 to 3 places to modify this key. On my computer, I have to modified them in CurrentControlSet, CurrentControlSet1, and CurrentControlSet3.
e. Restart your computer
2. After restart, right click on your speaker icon on the taskbar and choose Recording Devices. If you don't see the Stereo Mix listed, then right click on the Microphone and selected "Show Disabled Devices" and Show Disconnected Devices". You should see the Stereo Mix in the list now.
(IF YOU STILL DON'T SEE IT, THEN MY FOLLOWING STEPS WON'T HELP YOU. YOU MAY NOT BE ABLE TO DO STEREO MIX THEN.)
3. ONLY DO THE FOLLOWING IF YOU SEE STEREO MIX DISPLAYED IN STEP 2
. Modify your speaker setting
a. Click on the Playback tab, and then Properties.
b. click on the Levels tab of Speakers properties
c. On the speaker icon of Microphone you should see a red stop sign next to it. That means it is disabled. Please click on that icon to enable it. I also move the bar to over 50 so I can hear it.
4. READY FOR SOME MIXING:
a. Go back to your Recording tab, Stereo Mix should have been displayed with an arrowed pointed down, while your Microphone is displayed with an green check and "Working"
b. Right click on your MIcrophone and select Disabled
c. Right click on your Stereo Mix and select Enabled.
d. Now you should SEE YOUR MICROPHONE WITH AN ARROW DOWN, WHILE THE STEREO MIX WITH A GREEN CHECK AND "Working"
c. Also, the little volume bar next to Stereo Mix should moving up and down as it picks up signal from your computer.
YOU ARE NOW READY FOR STEREO MIXING.
4. testing out.
a. I just use audacity, and in my recording option in Preferences, the stereo mix showed up. I select that and then start recording. You can use your own recording software to try it.
HOPE THIS WILL WORK FOR EVERYONE.[/b]
