I plugged in my guitar to my headphone jack, and tried to record on Sound Forge 6.0 (the problem i mention also occurs with Acid Music 3.0). The guitar's sound came out my speakers as I played, but the programs would not record the music. It didn't recognize it. Then my brother sent me a link to the compaq website and I downloaded a driver that he told me to.

That then made my problem the opposite--I can now record onto both programs, but the sounds do not come out my speaker as I play them. They do however, come out during playback, but I need to be able to hear it AND record it as I play it.

I'm thinking its the computer, not the programs, that I must configure, but I know little about computers. I contacted compaq support, and they said its called "full duplex" and I must call the acid support for help. Well, in the program's help index, there is no matching results when I type that in.

Any suggestions? Anyone ever experience this problem? Or just know how to fix it??

Thanks.

Try going into your soundcard's software mixer, enable both the output you use for playback and the input you use for recording. Be sure the volume of the input is turned all the way up.

You should be able to hear playback of anything on your system while playing your guitar at the same time without even recording.

Older soundcards of yore could not do full duplex, but I can't imagine even today's soundcards not being able to do full duplex. Still, if it's a cheap soundcard, don't rule that possibility out.

Compaq was a little erroneous. Full or half duplex is hardware related.

HTH,

That sounds like a good way to fix it. I hope my soundcard allows full duplex. Hell, i know it can, cause i had it working at one time, but i have no idea how it just stopped. maybe software updates and other things could cause some settings to be automatically changed.

-However-

I don't know much in the way of computers. I know how to get the computer's "Volume Control", but no idea to access the "soundcard's software mixer." where do i go to access this?

Ok, I think I might know where you are talking about. If i go to that Volume Control, It has these things listed: "Volume Control" on the very left, which is half up. Then there is "Wave" "SW Synth" "3D Depth" "Mic" "Line-In" and "CD Player." Both Mic and Line-In are up all the way. then, when I go to "Options" and select "Properties" it shows that "Playback" is selected. I switch it to "Recording" and these follow: on the far left is "Recording" but this is gray, or disabled. I can't move it, but the slide is almost all the way up for it. But the fact that its faded, does that mean anything? then after that is "Stereo Mixer" "Mic" "Line-In" and "CD Player."

Is this the software mixer that you were talking about? If so, nothing is muted and none of the slides are fully down. the farthest they are down is half way. Am i on the right track? What should i do?

Waiting for a reply I decided to mess with things myself. I didn't know what i was doing so it was just fooling around, but Mic and Line in under the Recording Control were only 3/4 of the way up on the volume slide. I put both of them all the way up, and under Mic is a check box that says "Select." So i checked that. then i opened up my project and it works, so i think i fixed it. I thought they would work if the volume slide was up 3/4, I didn't knkow it had to be all the way up, but apparently that's what it is.

ok, you've got it to work, but just for reference...

when you checked the Select checkmark, that's when you solved the problem. the changing of volume didn't really have anything to do with it, since 3/4 al the way up is usually good enough.

you have to look at it like this: in the Recording Control panel of your soundcard's mixer you can specify where the soundcard should get the input source from. for example, if you've put your guitar in the soundcard's line-in jack, then you should select Line-In in the audio mixer. if you put it in the Mic plug select Mic (Line-In is usually better quality, but i don't really know if that goes for guitars as well).

now, the sound from your guitar will go to the PC through the Line-In input device. If you want to be able to hear or record this sound you have to go to the Playback Control in the audio mixer, and make sure the Line-In output is not muted.

so, the path of your sound is basically like this :

guitar -> line in jack of souncard -> Record Control panel: Line In -> Playback Control panel: Line In -> speakers.

Ditto what ATP said.

Sorry for the delay. Been clawing my way back here. There's a reason. ;o)
