Does Your Pma400 Take This Command?

Hi All,

I'm trying some simple stuff on my PMA400. It's strange to see that the sound card /dev/dsp doesn't work very well.
I started a terminal, and tried $cat somesoundfile > /dev/dsp. This playback worked well. However, the recording command, $cat /dev/dsp > soundfile, didn't record anything. I opened this output soundfile with a audio editing program, it showed a flat line. BTW, all hardware recording settings were good.
Does your PMA400 works well on this command?
Help guys help.
