Hi all,
I have problems removing input and output with loops devices: It
crashes ecasound. You can see an example like the next:
$ ecasound -a:1 -i:test.mp3 -o:loop,1 -a:2 -i:loop,1 -o:alsa,auriculares -c
> ao-iselect 2
> ao-remove
> ao-iselect 1
> ao-remove
> ai-iselect 2
> ai-remove
Segmentation fault

My objetive is change the test.mp3 to another mp3 file, do you know
another method?

Regards:
Pedro

$ ecasound -a:1 -i:/home/pfructuoso/tmp/test.mp3 -o:loop,1 -a:2 -i:loop,1 -o:alsa,auriculares -c
