The computer uses a 5-channel sound card, but even if the speakers are adjusted to 4 boxes, some games can only get the audio output in 2-channel mode. What is the reason?
The existing PCI 128 driver allows 5-channel audio output for any Direct X-based game, but cannot achieve 5-channel output for mono signals, and can only output stereo signals. Therefore, it is likely that the audio output of the game only supports mono signals. Similarly, the audio driver can only output from the two front channels. At this time, even if you turn on the "5 speakers" mode in Creative PC 128, you can only hear the sound from the front two speakers.
