5.1 Optical Audio Output Channel Mapping

For users with surround-sound speaker systems but only stereo output from the PC, we on-site configure the onboard or dedicated sound card driver panel. This includes correctly mapping each channel to the respective 3.5mm jacks or optical SPDIF output, adjusting the bass management crossover frequency, and testing phase alignment for each channel. We also resolve HDMI/DP audio return channel (ARC) switching logic between monitors and amplifiers.

No hardware speaker tuning or room acoustic modification is involved. After deposit, our engineer prepares driver presets based on your audio chip (Realtek/C-Media etc.). The final fee is calculated by the number of channels and output link complexity. We carry various adapters to accommodate the diverse active speaker interfaces common in the European market.
