Audio Settings

[Caseyjones]

I have been running my system for a number of months and it works great. Thanks for a great product sub.

The only thing that I can't get sorted fully is the sound, I would like it, that when it's playing a 2 channel source (recorded TV and music) its gets mixed upto 5.1.

My MBoard has Realtek HD Audio.
The settings I currently use are

Video Decoder: CyberLink Video/SP Decoder (PDVD7)
Audio Decoder: CyberLink Audio Decoder (PDVD7)
Audio Renderer: CyberLink Audio Renderer (PDVD7)

Other Audio Decoders I have tried are
AC3Filter

I assume its the decoder that would do the mixing up (as renderer doesn't seem to have any settings), but I can't find the holy grail of a mix 2 channel up switch.

Has anyone got non 5.1 sound playing out of 5.1 rear speakers?.
If so what Decoder/Renderer/MBoard do you have or is it that I have missed the setting in AC3Filter or Cyberlink?

Use AC3 filter, and set the type 3/2+SW and click the SPDIF.

Under the system, you will have to change the "restrict spdif sample rate' to both 48.1 & 44 kHz to have mp3 etc upmixed.

I have all recordings playing through 5.1 SPDIF, but leave 44 unchecked so mp3 etc play as 2 channel (the upsample doesn't sound so nice on music IMO - my amp can play 5 channel stereo which I use for music)

make sure the use AC3 encoder is checked in the system tab, as well as DTS /AC3 passthrough (if going to an amp) so it's passes through real surround instead of decoding and re-encoding.
I use system defaul as my renderer in gbpvr config.

I think I have the same on-board audio as you, and it seems to work as you want it.

No that didn't work for me. (Using 1.46 AC3Filter) I'm not using the SPDIF output but the 3.5 jack plugs.
If SPDIF is enabled I get no sound. With it disabled I get normal 2 channel on everything bar movies.

Sorry, I misunderstood - I don't know of anysoftware which will upsample analog to 6 channel, but you could try the realtek HD audio manager and see if you can make it use all speakers, but I dont think it will sound too good.

Do you have a receiver, or are you using a 5.1 system from creative or similar?

There is a "Speaker Fill" option in the Realtek Sound Manager. Turning that on will make 2 channel audio fill all the speakers. Also, you may want to set you audio renderer to "System Default".
