@Elez: "seemingly erratic" is actually expected behaviour. Other non- Debian-based distros may have already applied an index parameter to USB sound devices driven by ALSA, but as far as I can tell, neither Debian nor Ubuntu has done anything of the like.
I would also consider the ability, in Dapper's GNOME, to change the default sound card using the System> Preferences> Sound> Set default sound card menu item something considerably less ominous than "insurmountable". Nevertheless, I'll add the options line for snd-usb-audio soon. -- Hotplugged sound devices get sound card index of 0 instead of PCI card https://launchpad.net/bugs/46996 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
