I have two sound devices. One is an on-board NVidia PCI bus device. The second

attached, only the USB sound device works and the NVidia PCI device is not
recognized.

If I then run 'alsaconf' the USB device disappears and the NVidia PCI device
alone is shown:

If I then unplug the USB headset and insert it again, both devices will show
and work properly:

How can I configure the system so that both devices will work from the get go,
without the need to run alsaconf and remove/reinsert the USB device?
My OS is Debian etch

A workaround,
Identify the kernel module being used by the Logitech USB Headset and
manually load it.
Script at /etc/rc2.d/S99fix-audio:
1.run alsaconf
2. modprobe logitec-headset-module
It seems that when you run alsaconf it removes modules ("Unloading
ALSA sound driver modules") but fails to load them all back. That
might be the reason why you don't get your logitec device back after
alsaconf finished. When you plug the USB cable out and back in the
udev daemon taken care to load the appropriate module. You might want
to check /etc/udev/rules.d for proper loading clues.
