I'm trying to record from the built-in mic in my laptop (Dell Inspiron 4150)
but it doesn't seem to work right. If I select "Mic" as the capture source
and max out the volume then when I tap the microphone I can hear it loud
and clear in my headphones. Then I try:
[EMAIL PROTECTED] patches]$ arecord -d 5 foo.wav
Recording WAVE 'foo.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
I tap the mic a few times as this is running. I hear the taps great while
recording, but playing back foo.wav I just hear static, with the taps
barely audible. Adjusting the recording levels doesn't change anything.
If I try:
[EMAIL PROTECTED] patches]$ arecord -f cd -d 5 foo.wav
Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
then I get a 5 second wav file that's completely blank. As far as I can
tell, any format that's not U8 has the same effect.
Any ideas of what's going on? Here's some info about my system:
[EMAIL PROTECTED] patches]$ cat /home/n8gray/.asoundrc

Let me know if there's anything else you need to know.
Thanks,
