My OS is win 7 prof 64 bit and my pc is a Lennovo M72E. I had an external speaker connected, which I removed as the sound quality was so bad. This speaker was connected to the front of the pc. The speaker was : DTSS 2400 Theatre Sound System FPD 2485 W.
But now I cannot get any sound at all even from the build in speakers, not sure whether there are any.
Hope the Gurus can please throw some light. Thank u.
