Could it be a digital signal causing the problem?

I can record if I plug it int the mic jack but the quality isn't as good. I've used aumix to set the level of the line-in to 64 which sounds good. But recording with sox gives me nothing but silence. Ie: $ aumix -l 64 -m 64 $sox -t ossdsp /dev/dsp bogus.wav That works if I have my VCR connected to the mic although the quality is poor. Can I tell it to record from the line-in but not from the mic? Maybe aumix isn't the best tool to use. Alternately, maybe I could get the mic to work... The problem with the mic jack is that I get only the left or the right channel. I have a cable with 2 RCA jacks on one end and a stereo jack on the other. The 2 RCA jacks are plugged into the line-out on the VCR, left and right. The stereo jack is plugged into the mic on the sound card. Only 1 of the RCA jacks matter. The other I might as well leave dangling because I don't hear that channel no matter what. I can get the left channel on the VCR if i plug the jack that works into the left line-out jack on the VCR or I can get the right channel by plugging it into the right line-out jack. So the mic is acting as if there's a stereo-mono converter in there somewhere. I know the cable is good because: 1. I can hear both channels if I plug it into the line-in on the soundcard. But as I explained above, then I can't record. 2. I have a second cable and that one does the same thing 3. Both cables work fine with another sound card _______________________________________________ Speakup mailing list Speakup at braille.uwo.ca http://speech.braille.uwo.ca/mailman/listinfo/speakup
