Suddenly lost all audio plus volume icon in sys tray. Control panel/sys/device manager/sound-video states all devices working. Voyetra/snd chk states all WAVE and MIDI drivers failed to initiate [not working] due to address or IRQ conflicts. Every attempt to run a self diagnostic test causes a crash [DIA caused a fault in MMSYSTEM.DLL] Keeping in mind I'm not a computer tech, how do I fix this?? OS is Win 95; IE5.5. Appreciate any help
