View Full Version : WMV HD - No Audio Playback

21-11-2004, 02:55 PM
I downloaded one of those 1080i HD Windows Media Files to try out...

Excellent video quality but no audio playback unfortunately. I have the necessary specs and experience no video playback lag. I also have a SB Audigy DE with latest drivers and WMP 10. I have no problems playing DVDs/DivX files in full Dolby Digital 5.1 and can play multi-channel WAV files also.

The problem seems to lie with the decoding of WMA 48kHz/24bit multi-channel audio as I have the same problem with a standalone WMA audio file of similar spec.

Any ideas?

The audio compression used is:

Windows Media Audio 9 Professional
384 kbps, 48 kHz, 5.1 channel 24 bit (A/V) 1-pass CBR

WMP should be able to decode this natively...

grr :(

Nevermind > solved issue...

You have to feed the audio to the DirectSound device and not directly to the soundcard - didn't think it would make any difference...

oh well :)
