i lost this device and now have no sound. it was removed from device mgr.,system, it originally had an exclamation mark on it and thought if i removed and re-install that would correct the problem. now i can't reload it or even find it . the original error message was : windows can't configure audio devices. audio files are loaded and updated but not turned on. i seem to be unable to install swenum.sys file which i need. the file is in my machine but i can't execute it. how do i re-install the plug and enumerator? walter929
