[QUOTE="Taipan, post: 17706, member: 11681"] I have a similar set-up. But the thumps are not due to the volume control settings in Windows, it is due to the output-coupling capacitors in the sound card charging up when power is applied to the PC. The only way to avoid this problem is to have a control from the PC to turn the amplifier's mute on and off at the appropriate times. For example, the amplifier's mute should be on until a few seconds after the PC has powered up, and then the mute can be turned off. Similarly, the amplifier's mute should be turned on again, just before the PC is powered down. I have been trying to figure out a way to do this within MediaPortal (via a startup and shutdown script) and control the amplifier's mute from the RS-232 port. Any suggestions are very welcome....
