Hello everybody,
I am having some issues making arecord use the default device for
recording. Could somebody help me get a working .asoundrc configuration?
I attached all information in the attachment and also made temporary
hyperlink: http://debian.pastebin.com/m52601230
It works with:
arecord -v -f S16_LE -r 44100 -D audiodevice0 ~/record0.wav
but it does not work with:
arecord -v -f S16_LE -r 44100 ~/record0.wav

Thanks in advance,
Best regards,
Jelle de Jong
