Re: Unable to do multi channel recording simultaneously using Ecasound

Hi Nishant,

>From the error: ERROR: [ECA-SESSION] : "Audio object "foo1.wav-a:2"
It looks like you do not have the correct spaces between the first and
second chain.  Therefore it is trying to process "foo1.wav-a:2" as one
object.

Try the command on one line to see if that helps.  Like this:

ecasound -f:24,1,44100 -a:1 -i jack -o foo1.wav -a:2 -i jack -o foo2.wav

Cheers
