Hi I have sound card issue appears every starting BackTrack 5 R1 64 bit :

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: HDA Intel (ALC888 Analog)
Output: Ensoniq AudioPCI ENS1371 (ES1371 DAC2/ADC)
Output: HDA Intel (ALC888 Analog)
Output: HDA Intel, HDMI 0 (HDMI Audio Output)
