By searching the forums I know that I am not the only one with this problem. I have an external Sound Blaster Live! 24 Bit External sound card (sounds much better than the onboard sound on the M10000). Each time I resume from hibernation it is muted. Anyone know of a solution for this? I thought about using Frodo's setvolume app to unmute upon resume, but does anyone know why it mutes in the first place? I'll buy you a beer if you can help.
