Channel/resolution combinations that would exceed this need to be compressed. The maximum permissible total bit rate is 9.6 Megabits per second. For example, the front speakers could be 96/24, while the surrounds are 48/20.Īudio is stored on the disc in Linear PCM format, which is either uncompressed or losslessly compressed with MLP (Meridian Lossless Packing). Also, the channels of a track can be split into two groups stored at different resolutions. For instance, a DVD-Audio disc may contain a 96 kHz/24-bit 5.1-channel audio track as well as a 192 kHz/24-bit stereo audio track.
I went to all that trouble with drivers and found that the default MS driver that came with WinXP worked perfectly.DVD-Audio (commonly abbreviated as DVD-A) is a digital format for delivering high-fidelity audio content on a DVD. I then played my DVD, It worked perfect in 5.1 via the Digital Port on the card. After that I went in to the sound properties and set digital out only.
I uninstalled the kX driver and removed any evidence of the creative drivers.Īfter a reboot Windows XP installed its own Microsoft driver. I was about to give up and buy another sound card then I though lets start again from the beginning. The AC3 encoder appeared to be sending the rear channels to another SPDIF port. I like them a lot, but it would not let me turn the AC3 decoder off therefore I was only getting a stereo signal sent to the AMP. I tried the kX Project drivers, very, very, kewl. Some of them produced the same result while others skipped. There was no sound when it played at double speed.
Now when you play a DVD the DVD plays at about double speed in random sections of the DVD. This stopped the Blue Screen problem but introduced another problem. So I upgraded the drivers to the latest Creative drivers. The only problem I had was it would sometimes blue screen on boot.
It sent the DTS or Dolby Digital 5.1 code to the AMP and the AMP decoded the signal and gave excellent 5.1. These were obvious settings within the Creative Mixer. With the creative drivers all I had to do was turn the Digital output only on and the AC3 decode off. I was told that the only way I would be able to get the 5.1 sound to work from my DVD's was if I used the Creative drivers. This cable is running from the digital out on the sound card to the Coaxial in on the AMP. I’m also using a Sony DTS/Dolby Digital 5.1 decoder that is built in to my AMP.
