@Elez: The same thing we Xfce users do, which is to call asoundconf(1) directly (which is what gnome-control-center's applet does anyhow).
$ asoundconf list should return strings of recognised drivers. Then use: $ asoundconf set-default-card string as a convenience. Afterward restart all ALSA applications. -- 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
