I'm having problems recording from line in. Without knowing exactly what's going wrong, all I can say is that I can only playback "silence." As I'm recording, I can hear the audio being fed back through the external speakers. I can also use various mixers to mute/unmute and set the volume on the "Line" setting. So I'm pretty sure everything is hooked up right. I initially tried using sox/notlame/mpg123 ... # record and encode $ sox -t ossdsp -w -r 44100 /dev/dsp -t cdr - | notlame -k -v -S - /tmp/out.mp3 # playback $ mpg123 /tmp/out.mp3 I've since tried to simplify things ... $ rec -d /dev/dsp /tmp/out.wav $ play /tmp/out.wav Neither of them work. System details are provided below. What else can I do to troubleshoot this? Thank in advance - gary System . redhat 8.0 (2.4.20-19.7) . alsa-0.9.6 .
