Ffdshow may be better option where setup properly
How can I send the audio to my receiver instead of my PC speakers?
Most receivers are able to decode AC3 and DTS audio. If you have connected your receiver to your PC with a digital cable, then you can send AC3 and DTS audio directly to your receiver by using S/PDIF pass-through.
It is also possible to output other audio formats to your receiver by re-encoding the audio to AC3 in realtime.
The location of the S/PDIF options depends on which decoder that you are using, either ffdshow or AC3Filter. The codec pack uses ffdshow by default.
In ffdshow audio decoder configuration, go to the "Output" page. There you can find checkboxes to enable S/PDIF pass-through for AC3 and DTS audio.
If you also want to send the audio from other audio formats to your receiver, then you need to enable the "AC3 (S/PDIF encode mode)" checkbox under "Supported output sample formats".
Only the audio that is processed by ffdshow will get re-encoded to AC3. If you also want ffdshow to process audio that has been decoded by a different DirectShow filter, then you need to go to the "Codecs" page in ffdshow configuration and set "Uncompressed" to "All supported".
To activate S/PDIF output, enable the checkbox called "Use SPDIF" that is located on the "Main" tab.
All S/PDIF options in AC3Filter are located on the "SPDIF" tab.
If you want AC3Filter to process audio that was decoded by a different DirectShow filter, then you need to enable PCM on the "System" tab.
Ahh finally got it to work but audio is delayed by like 1-2 seconds .... Perhaps it doesn't help with me using a 10m HDMI and 10m optical cable....... Is there a way to speed up the audio?
The cable doesn't matter. To get a 1 to 2 second delay from the cable you would need about 186,000 miles of it.
hmm, why is there a big delay then? ... dont have this issue with AAC to AC3 with ffdshow and GOM/KMPlayer.
One of the filters may be buffering.
I hope someone knows of the fix
