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.
