I'm having problems with Windows XP.
The motherboard is the K3Ultra2 by MSI with a 1.7 Athlon XP processor usinf Windows XP Home edition. VIA chipset on motherboard.
Symptoms:
The SPDIF output only streams Stereo PCM - I cannot get Dolby Digital streams output from a sony digital receiver. When I run this in WinDVD - no sound and receiver acts like no its non-signal.
Test:
Tested this on the embedded Realtek sound SPDIF on motherboard K3Ultra2 as well as on a C-Media (Zoltrix Nightgale) - Same behaviour. Turning on SPDIF in WinDVD results in no Dolby Sound (no sound at all) but clicking back to two speaker the PCM Stereo in then received and sound comes on.
The strange thing on an INTEL motherboard (800MHz) different motherboard (VIA chipset as well) the same sound card (Zoltrix Nightgale) works in Dolby Digital in WinDVD with SAME operating system.
So negating the sound card and drivers working on one and not the other eliminates sound card, drivers and the OS system but points to hardware.
Does anyone have any clue or pointers I could try out.
Someone suggested bad DMA from the DVD reader (Lite-On DVD drive reader).
Anyone out there?
DA
