PowerDVD 2 speakers vs 4 speakers

[coch]

Hi,

I'm having a problem with PowerDVD 5 right now, but PowerDVD 4 also had the same issue.

The problem is that if I choose 4 speakers configuration, I do not get sound from my read speakers. If I choose 2 speakers, then rear speakers work, but I guess it is not real quadraphonic sound, only front channel sound sent in the rear. This is really weird. Anybody has any input (read: a fix) to this?

I run PowerDVD 5, on a fresh install of Win2k SP4, but the problem also occurred on Win98SE, and with PowerDVD4 on both Win2k and Win98SE. I have a SBLive with the latest driver.

Thanks in advance.

do you have 5.1 speakers with center/sub ?
or only 4 speakers ?

check if you have selected the right number of speakers
in "Control Panel" / "Multimedia"
and in "Creative Surround Mixer"

Yes, in fact I have 2 rear speakers, and in the front I got 1 sub, with 2 more satellite speakers hooked on on the sub.

Settings in both creative mixer and windows control panel are correctly selected.

Any other clues?

(by the way, doesn't creative mixer settings are in sinc with windows settings? I mean, can settings on both places be different?)

try using a different speakers configuration in PowerDVD
(4 speakers, 6 speakers, 5.1, surround, ...)

Thank you for the help. Let me clarify further:

On the front channel, an audio cable goes out of my soundcard to the subwoofer. The sub has an audio input jack, and an audio output jack in which the 2 satellite speakers are plugged

Yes I do have the latest PowerDVD version. Well, I do not get a lot of feedback, so it seems I might be the only one seeing this. There must be something on my system causing this. Not the OS, as I've seen this on 2 OS. Not PowerDVD itself, because every version I tried since 4.0 does this. Not the sound card, as it was also doing this with my previous one (Diamond Mx300) aaah. I just recalled something. With my previous soubnd card, this didn't occured when playing DVDs, only when using PowerDVD in file mode to listen to DIVX, or in VCD mode. For DVDs ot was fine. Perhaps it is the same here, as it is a DivX I'm trying to listen. I do not have a real DVD to test though.

Doesn't explain why the settings act so weird though, but perhaps it is a clue.

Comments anyone?

most DivX files and VCD are Stereo (only 2 channels)

if you choose 4 speakers configuration to play stereo files, it's normal to get sound only in the front speakers

in PowerDVD, choose 2 speakers configuration with :
"DirectSound3D" or "Dobly Virtual Speaker"
and "Audio Channel Expander" :
"CLMEI" or "Dolby Pro Logic II"


change it back to 4 speaker when you have a real DVD to test.

thanks a lot for the help, the VCD/DivX probably explains what I am seeing.
thanks again

i found a new DirectShow Filter for upmixing from any stereo source up to 5 channels.
