Here are my results with this mainline kernel:
    Linux fatso 2.6.35-999-generic #201006021335 SMP Wed Jun 2 12:39:19 UTC 2010 x86_64 GNU/Linux

Additional hardware shows up in the Sound Preferences before the
Plantronics USB audio device is plugged in. This appears to be because
the snd_hda_codec_nvhdmi module is loaded when I boot this kernel.
    High Definition Audio Controller
    1 Output
    Digital Stereo (HDMI) Output

Normally, I just see:
    Internal Audio
    1 Output/1 Input
    Analog Stereo Duplex

After I plug in the Plantronics USB device, I see:
    Plantronics Wireless Audio
    1 Input
    Analog Mono Input

When I unplug the Plantronics USB device, the Sound Preferences does not
remove Plantronics from the Hardware tab as with the normal Lucid
2.6.32-22 kernel.

I have attached the section of the kern.log when I plugged in and unplugged the Plantronics usb device.
