I am using an IBM T41 Thinkpad laptop with Windows XP and a phono pre-amp for recording LPs which I then make into WAV files and put on CDs. As the Thinkpad does not have an audio interface beyond the mic-in, I got a special Docking Port which has a line in connection. This system works but there are a number of curious features which I hope you can shed light on.
- The recording Input levels are substantial even when there is no signal input.
- The two channels are not matched. The left channel shows a higher reading than the right channel, even when there is no signal input (even when nothing is plugged in but the record button is depressed).
- Does this indicate that I need an external sound card?
- Is the Behringer UCA202 an external sound card? (It is listed as an audio interface and not as a sound card, but many also refer to it as a sound card.)
