hello guys.
I'm new to 'backtrack', before I used Ubuntu 11.04 .. Today I installed the 'backtrack 5 KDE 32-bit. ".
after installation, I started the system but an open window, saying it gave error in the audio sound.
in the window that opens says the following error:
__________________________________________________ ____________
Removed Sound Devices
KDE detected that one or more internal sound devices were removed.

Do you want KDE to permanently forget about these devices?

This is the list of devices KDE thinks can be removed:
-Capture: Ensoniq AudioPCI ENS1371 (ES1371 DAC2/ADC)
-Capture: saa7134[0] (SAA7134 PCM)
-Output: Ensoniq AudioPCI ENS1371 (ES1371 DAC2/ADC)

( ) Do not ask again for these devices.
