Another thing to try is to disable the 32 bit FP output mode in FFDSHOW. Some sound cards (especially low end or onboard ones) don't properly support 32 bit or floating point sound sample formats. Usually this manifests in
extremely quiet sound (particularly the center channel in a multi-channel setup), but sometimes it silences it altogether....
Go to
Start --> Programs --> Combined Community Codec Pack --> FFDSHOW Audio Decoder ConfigurationIn the dialog that appears, choose Output from the list on the left. You'll need to scroll down to find it, it's all the way at the bottom. Then uncheck
all of the boxes under "Supported output sample formats" except 16 bit integer.
Click OK to close the dialog and try to play back your video file. If you get audio, then great, we figured it out. If you want (and by no means do you have to if you don't) you could go back into that same dialog and start re-enabling those check boxes
one at a time to figure out which one is causing the problems. I'd guess if any of them, it'd be the 32 bit ones. However, this is really unnecessary if you're just using cheapo onboard sound anyway, and for best performance you could just leave 16 bit only selected. That's up to you.
If this doesn't work, we can try something else as well, but I suspect this might cover it... Still check CCCP Insurgent for me (from above) though, because if there is a conflicting codec/filter pack on the system it could be causing lots of other problems...
