No sound when playing DVD

Does the laptop play CDs?
If so then when you start a DVD and before you play the movie, go into the audio setting and configure the speakers for laptop stereo speakers.
If you cannot hear music from the CD then check :-
1. The audio settings, volume not set to minimum and mute is not ticked (enabled)
2. Device manager - sound device is enabled and working, if not re-install the sound driver.

Install K-lite codec pack. Or some recommend VLC player. Your missing codec.

Have a nice day.

Here is a simple way to find out if it is the program that you are using or actually your computer. What I am going to do is list a link at the bottom for you to install and try and watch your movies on. This is called VLC it is a movie player with a bunch of different codec's. You can think of a codec as a way to translate the designed language of the movie into audio and video. Different movies are written in different ways and not all programs have all of the correct codecs. But anyway VLC is jammed packed full of codecs. I use it personally, never had a issue it works amazing. This is my quickest and easiest solution.

I have a DVD player, a VCR player, a TV set all hook into an RCA RT2250 Audio/Video receiver. Everything was working fine until 2 days ago. Now the DVD player gives me a great pix but no sound. The VCR,and TV are just fine and I have checked everything out, speaker connections, mute buttons, etc. and nothing seems to be wrong. I am thinking that some thing in the receiver got fried. Is it repairable?
