Can't control Input Volume

[Fred7]

Greetings All...First post!
I am running the latest Audacity - 1.3.12 - In Windows XP Pro on an Acer Aspire Laptop. I am trying to load into this computer my audio tape library for conversion to CD. My Input Device is a Digitech Audio USB Cassette JW-51-SWG. The computer does not have a 'Line-In' port, only a mike input, so I can only use the USB system.
The first two or three loading attempts were successful and pleasing. Good audio quality...etc. However, the next tape playback was severely distorted, with heavy "clipping".
Attempts to adjust the Audio Input Slider bring up the dialogue "Cannot control input level; use system mixer", as the cursor hovers over the slider (but no trouble with the PlayBack Slider). I have tried double-clicking on the volume control in the system tray, and bringing up the RealTek display & adjusting those sliders, but nothing works. I don't know where else to look for a "system mixer".
The most frustrating thing, which inspired this plea, is that, on my most recent attempt to upload, the first track was perfect, even though I don't know what I did to make that happen, but the second track went straight into overload as I watched the monitor, and also 'skipped' a couple of times. I hadn't stopped the tape between tracks, just let it run, and intended to let it go to the end before stopping.
I suspect there is a software problem, but its cause, and how to fix it, is beyond me.
Can anyone help......??

Best regards,

Fred

I can't find the Digitech Audio JW-51SWG - in fact I can't find Digitech Audio
Does the device have a volume control that affects the volume level that is sent to the computer?

Thanks whomper, but doesn't really help without any technical information (or preferably a manual). The best I've found is a photo - but that's not much help either.

i found a lot of places that claim to have a manual too

did not try to dl any of them

if you have a question
then ask the OP
and have him get the info from his seller
or dl the manual for you
