I have a laptop on Win XP SP3. It is no longer able to play any sounds (it could a couple of days ago).
Device manager shows all devices working OK
System volume is not muted nor are wave, SW synth and CD player.
It uses Realtek HD audio - looking at its control panel it seems to be normal
I've tried the Windows online help - it found no problems
Neither internal nor external speakers work. I've tested the external ones and they are working.
Can you please suggest what else to try or repeat?
