Hi there! So my problem is...annoying and getting me mad. - When You switch to te LaunchPad there is this sound environment ( like pumps, generators running ) After launch it stays during the whole flight. Getting back to any other window - space centre , vab, etc. makes it dissapear - new sound env. loaded. But after switching to the flights - the lunch pad environment gets back! All sound all played correctly, background music, decouplers, engines - but there is still "the lunch pad main theme" in foreground. Any further questions are welcome. When this all might sound... to You unclear. Best regards Alan
