My goal is to record speech from four different microphones (mono inputs) and store it in correspondig four sound files. Then I should be able to reproduce them simultaneously, in parallel on four outputs or mixed together.
I'm quite new to both ecasound and alsa, and I have some problem.
My system is based on an AMD Athlon 2000+ with:
- on-board VIA 8235 sound card;
- one added M Audio Delta 66 sound card;
- Linux kernel 2.6.3;
- ALSA driver 1.0.2c statically built into the kernel;
- ecasound v2.3.1.
The four input I would like to use are those of the Delta 66.
I can record sound from inputs 1 or 2 with the following command:
# ecasound -i:/dev/dsp1 -o:out.wav
But when I try something like:
# ecasound -i:alsahw,1,m,n -o:out.wav
whith various values for m and n (included 0,0), it doesnÂt work.
I get the following error message:
(eca-control) ERROR: Connecting chainsetup failed: "Enabling chainsetup: AUDIOIO-ALSA: Audio format not supported.
And what about inputs 3 and 4?
In other words, what is the right syntax to point to single input/output lines of the Delta 66 through alsa?
Thanks for every suggestion!
