DVDs wont play sound on Dell Lappy

OK_Sauce

My laptop (a Dell Inspiron from one of the deals some time ago) used to play DVDs with no problem using WMP10 and the onboard Dell Cine player. Recently I installed Nero and copied a DVD video prog which I bought from the states.
Now I cannot get any sound from any DVD I play on it. The DVD and the copies play fine on other DVD players. But any DVD I now put in the lappy are mute. I've gone through all the possibilities I can think of, ie checking nothing is muted. Could the Nero program and copying facilities have done anything to cause this?

I heard someone with a similar problem, after installing Nero (that incorporated InCD within installation). Once InCD uninstalled, DVDs played perfectly.
Hope that works for you.

I have uninstalled Nero, now I'll see if this inCD is separately installed. Thanks.

There's no sign if InCD on the lappy

I guess a normal CD plays OK through MP10 - worth a check? Any sounds from other devices play ok? (.wav, .mp3...), but I guess yes, or you would haven't such a specific query. Sorry, I probably can't help much... but someone will! There's always a roll back to consider, to a time prior to the first Nero install?
I have Nero, and on installation did a custom install, so that it didn't put all the other associated programs on at the same time.

Yes, everything works except DVD sound. How do you roll back to a previous state? Certainly worth trying!
