Hello, my 1st post on this great forum (have been reading a lot). Had to register just to tell the tale about my quest for Windows 7 stereomix recording (never had any problems with xp recording).
This pc is a HP laptop, amd + ADI soundmax. All sound worked well, with either Soundmax or MS driver. First, figured out quickly that the stock MS driver had no stereomix, hidden or not. The Soundmax driver had it hidden, & no problem in getting it active and setting it to default. But still no recording luck, neither Audacity or any other recording programs got any signal, & the stereomix barmeter in control panel > sound > recording was there, but showing no signal.
After some mad reinstallation of drivers and all kinds of experiments and 150 reboots
with no luck, when on the verge of reinstalling Windows 7 I found the solution for this particular case: the modem
(yes, telephone line) was disabled in bios, and had influence on parts of the audio system. Got a clue when I looked at the 'communications' in sound control ("When windows detects communication activity" > mute all > reduce volume etc). Enabling the modem and restart: Stereo mix alive and well ! Jez.
This may not be of help to anyone with different systems, but it shows how frustrating the setup of stereo recording can be in Windows 7, and it seems like different pc's may need their own special solution. But, at least I can safely say that whatyouhear recording in Windows 7 is
possible and works, just a matter of solving riddles.
