I did some minor changes since last system restore, i probably forget how i set them previously to work fine and now when I set them to correct values I am amazed at the way how they work. I selected "digital" playback and enabled "error correction". This has been archieved by adjusting "Audio CD F:" properties.
windows media player is after all able to play CDs via SPDIF interface without chops. anyway i was not able to reproduce my current system configuration. I use Creative Sound Blaster 5.1 with WDM drivers. I found that i can play 4,1 (or 5,1) sound while in Surround mixer i can set any of the effect ON. Effect: Enhanced DVD video playback, visible better color quality. I was able to set "VMR9 Mixer mode" On in Media Player Classic. But for me its strange to know that 10 years hardware has better sound as the new one.įour things happened: 1.
But is there any software able to play from SPDIF? Will see. If I will be able to connect the DVD drive directly to the SPDIF it might help to improve sound quality. At all the card is able to output sound in 44Khz Still the older system has one less possible degradation. When CPU is involved another sound stuttering might occur during high load of system. there is not direct sound - therefore there is no pure hardware acceleration. Sound quality from CD has been here downgraded for the first time. Until i construct that cable the sound must be "grabbed" and transported via ATA cable.
Still possibility to connect it via SPDIF IN but only via jack, not PIN. But no SPDIF input for standard digital CD input. SB Live outputs sound natively in 48KHz while CD format is 44 KHz. But here the first and last degradation occurs. Therefore I believe that sound is processed via soundcard without any direct need of CPU. to re-test it i have run program which consumed up the CPU, but the sound was still perfect. But when it was done, and WMP has been tuned up to use digital-CD-IN the sound was very very good. No other software except WMP 9 was able to run it.
Ok lets talk about the sound hardware I used: Soundblaster LIVE 5.1 (with SPDIF digital CD IN) And/or Soundblaster X-fi Fatality (extreme music) ATA DVD rom Samsung with SPDIF-CD Oout Bose speakers Software: Windows 98SE + KEX + Windows media player 9 WDM drivers for Soundblaster (they work by some miracle) Direct X 9.0 with Directsound and/or Windows 7 Ultimate 圆4 WDM drivers 32 bit Direct X 11 without Directsound (removed since vista) OpenAL, ALchemy Windows media player 11 (+-) Getting work SPDIF input on Win98 was a hard nut.
