My misunderstanding. In the past I had a version of Audacity which had a pulldown selection listing line_in, cd, mic and other choices for the input. I thought the current pulldowns were just to select the soundcard. From you comment below I understand that the sound card is using the input from all these sources simaltaneously and so the ones not needed must be muted. This new understanding does not help as I have already experimented with all the Alsamixer settings without Audacity seeing any signal to record. I have tried using line_in from my tape deck and lp turntable with the same negative result. What did help was the comment about other software. I found arecord works flawlessly capturing the input from the tape deck and the turntable and writing it to .wav files on the hard disk. Audacity can load these files so I can edit them before writing them to cd's. This is what I wanted to accomplish so mission accomplished. Thank you for clarifying the operations for me.
