Hi Dino, thanks for reply! :-) > I think that udev can does this job: > http://alsa.opensrc.org/index.php/Udev Mmmh, i was wondering if any asoundrc's magic could do this job... Maybe I explained the problem in a very dirty way; what i think is to have a "default" card configured (in normal laptop usage it's card0, the internal one) so default -> card0 and when i plug the USB card the link or reference as you want switches: default -> card1 If i work on udev level (my skill isn't the best on it) it's not a simple "link"/"reference" switching it's a totally device renaming... Am i wrong? In better way i don't want to act (rename) devices, i would redirect the sound stream to USB card only when it's plugged in. I read the "routing" plugin/function on asoundrc tutorial, can it become the solution? Thanks to all. ff0000 ------------------------------------------------------------------------------ Come build with us!
