No Sound on Laptop HP

First of all, to get digital sound on your laptop when connecting to external speakers, you should check for your HDMI cable. If that’s OK, then check for the amp and make sure you have set your speakers to output digital sound like Dolby Digital or DTS. This way the speakers will be ready to receive digital audio input from laptop.

Second of all, check for the DVD movie you are going to watch. Check whether it supports digital sound or not. If the DVDs don’t support it, then there is no way you can output digital sound out of the movie.

Last but not least, check for the software you are using to play the movies. Look for digital sound settings and set those to output digital audio. Some movie players don’t support digital output, so you should read the manual too to find out. You might want to use CyberLink PowerDVD as it support both Dolby Digital and DTS surround sound.
