Hi again,
Sorry for the delay in answering. I was trying to sort it out on my own, but it turns out I can't.
Some background: Engineer, 46 years old, leisure musician. Previous experience with this same version of Cakewalk, which used to run very well back when my computer was running Windows XP.
I have no plans to mimic a studio. All I wish is to record vocal tracks to facilitate my bandmates learning of their harmony voices. No requirement for any technical sophistication, end target is a humble mp3 file with one voice panned hard left and the others panned hard right.
Right now I have the Cakewalk Pro Audio 9 installed and running in my Vista laptop. No external sound card. I know it may sound like heresy to some here, but it should work with my signal input through the laptop microphone jack. It did in my old computer back in the day, so I see no reason it should not work now.
The symptom I am stuck at right now is that I succeed in recording my audio signal, but the recorded signal is very faint (i.e. weak, low volume). I know for sure that my input signal upstream of the laptop's microphone input jack is strong enough (the VU meters of my US Audio mixer indicate so), yet for some reason I get lots of noise and a very faint signal in my recorded audio track. So far I troubleshooted as follows:
1) checked and tried replacing each cable in the signal chain, from the microphone cable connected to the mixer up until the audio cable connected to the computer's microphone input. Nothing changed.
2) checked the Audio dialog box of windows (labeled Sound, with the little woofer icon) and confirmed that the "recording" tab has (under microphone properties/levels) microphone level set to 100 and the icon indicating that it is not muted. I also have microphone boost set to zero, because as mentioned earlier the signal coming from the mixer is positively hot enough.
Still I get a low signal with lots of background noise (no specific noise that I could identify, such as CPU cooler or anything like that).
I suspect some sort of configuration mistake, but have no real clue of what or where. Any suggestion - aside from spending money on another computer, etc. - will be much appreciated.
