Choosing between PCM (Pulse-Code Modulation) and Dolby Digital depends on your setup and needs. PCM is uncompressed audio, delivering high-quality sound but requiring more bandwidth. It's ideal for stereo audio sources or when using direct connections without an AV receiver. Dolby Digital, on the other hand, is compressed, supports up to 5.1 channels of surround sound, and is better suited for home theater systems to create a cinematic experience. Consider your equipment capabilities and personal preferences to decide which is best for you.
