We love home cinema setups. A quiet media centre PC , powering a projector, and connected to a surround sound amp makes for a formidable entertainment solution. For people from a PC background, though, the audio side of things can get neglected, but if you’re entertaining the idea of a big screen, you’re going to need a big soundscape to match.
We don’t have space to explore all the options here, but a good place to start is a suitable home cinema amp or receiver with matching satellite surround speakers, plus a low-frequency subwoofer. The next big thing is Dolby Atmos, which adds vertical speakers to the mix, but even a 5/6/7.1-channel surround sound option is going to be music to your ears.
One issue for PC audio is the distinction between ‘generated’ audio – from games, say – and pre-recorded DR M-protected audio, for movie soundtracks. The latter typically needs to be ‘passed through’ to the home cinema amp over a digital connection, else the DR M offers up the sound of silence. The flip side when using a digital audio connection is that you only get stereo output for ‘normal’ PC audio. The workaround is to use the audio jack’s matrix output, and decode digital soundtracks to analogue.
Once you have a big screen, you’ll want big sound to match, from something like this.
