I'm trying to digitize a tape. The tape deck output is attached to the
input of my sound card. I can hear the sound on my speakers, which are
attached to the same sound card; but nothing is coming out of /dev/dsp.
The mixer seems to work as advertized, volume and muting work OK. I've
tried activating recording, which (I think) is indicated by a red light
below the volume sliders for a number of diffreent inputs with no effect:
The commands:
$ cat /dev/dsp > foo
$ od -h foo
0000000 8080 8080 8080 8080 8080 8080 8080 8080
*
0410000
seem to indicate that the output of /dev/dsp is nil.
Any idea about what the trouble is, how to fix it, or useful info to
gather?
My setup is as follows:
Sound Card : Sound Blaster Live!
Drivers : ALSA Version 0.9.0beta9.
System : RedHat 7.2, kernel 2.4.7-10
