Intro, and, first question

[Jacob Kruger]

Thanks, Greg.


Have actually just found out that specifying device 1 works.


Oddly enough, if I run the arecord -l command, it only shows device 1, 
but, suppose that's since it's offering input, but, had thus not 
realised there was also a device 0 that just wasn't showing up.


In other words, the following command does now run through, but, with 
one more minor issue that will explain below:

arecord -D plughw:1 -f dat testing.wav


The issue have now come across is that it's most likely recording at a 
really low volume, or else will need to double check recording with 
different microphones hooked up to the USB audio adapter, since when I 
then copied the output file to my main PC, and, boosted it's volume 
using audacity, I just picked up some crackles, but, no actual voice 
input, but, will try it out with a different microphone now.


Main thing is it didn't bring up that error message, and, ran through, 
producing the output .wav file, etc.


Thanks, again
