    Two Sound Devices: PCI and USB. Strange behavior

    I have two sound devices. One is an onboard NVidia PCI bus device. The second is an USB headset.

    The problem is that when I boot up with the USB headset attached, only the USB sound device works and the NVidia PCI device is not recognized.
    Code:
    # cat /proc/asound/cards
 0 [Headset        ]: USB-Audio - Logitech USB Headset
                      Logitech Logitech USB Headset at usb-0000:00:02.0-2, full speed
    If I then run 'alsaconf' the USB device disappears and the NVidia PCI device alone is shown:
    Code:
    # alsaconf
Terminating processes: 5548.
Unloading ALSA sound driver modules: snd-intel8x0 snd-ac97-codec snd-ac97-bus snd-usb-audio snd-pcm-oss snd-mixer-oss snd-usb-lib snd-rawmidi snd-pcm snd-seq-device snd-hwdep snd-timer snd-page-alloc.

# cat /proc/asound/cards
 0 [CK804          ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at 0xf8105000, irq 225
    If I then remove the USB headset and insert it again, both devices will show and work properly:
    Code:
    # cat /proc/asound/cards
 0 [CK804          ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at 0xf8105000, irq 225
 1 [Headset        ]: USB-Audio - Logitech USB Headset
                      Logitech Logitech USB Headset at usb-0000:00:02.0-2, full speed
    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?

    TIA

    Similar problem with me...

    I have a Gigabyte K8N51GMF-9 with a nForce 430/6100. I am using the 8ch onboard audio and I have a Plantronics DSP-400 USB headset. I haven't found a smart way to switch the output between the two, yet. I mostly use the onboard sound but sometimes, for example, when playing CS in Cedega I want to use the headset.

    I will post if I find something.

    Welcome onboard the discussion.

    Curious, what method do you use to "switch the output between the two"?

    It's not the smartest way to switch between devices but for now it works.

    Enjoy!!!
