I have been successfully using an M-Audio AP 2496 sound card for several months.
Last night, without any change of configuration, I suddenly stopped getting any sound. After a little research, I found that DTS sources seem to be working fine, but DD 5.1 and 2.0 produces nothing. My receiver's indicator panel shows that only left and right channels are detected when I send a DD 5.1 signal to it.
To verify that this is not a receiver problem, I determined that I can successfully play both DTS and DD from my dedicated DVD player. When I use the HTPC, I can only play DTS.
One symptom is that all audio channel options on the Audio properties tab of WinDVD are disabled (greyed-out). Enable S/PDIF output is selected, which is the setting I was using prior to this problem, but all channel options are disabled.
I am using the deltawdmver51219.exe driver. In the M-Audio control panel, it says that my driver version is 5.12.1.10 and my panel version is 1.01.10. In the Patchbay/Router, I have H/W Out 1/2 set to WavOut 1/2 and H/W Out S/DIF set to WavOut S/PDIF. I am running Windows 2000 sp2. The windows control panel Sounds and Multimedia properties Audio tab has the Sound Playback preferred device set to Delta AP.
Can anyone suggest anything I can try to solve this problem? Thank you.
