multichannel extensible with Wavavimux

[new2doom]

I am trying to encode a 7.1 channel wma file. I have followed Microsoft's directions located here:
http://www.microsoft.com/windows/windowsmedia/howto/articles/creating71audio.aspx

The wavavimux tool created a 7.1 channel avi, which will play in Nero Showtime, but is unplayable in WMP and will not load into Windows Media Encoder. Gspot reports that it is an AVI with extensible wav format audio. However it also reports "unable to render the audio".

The source files I used are LPCM and play perfectly in WMP. What am I missing?

The source files for wavavimux must be 8 monowav's and you say:
"The source files I used are LPCM"

Please explain from where are your sources and the exact format.

The source files are mono waves created by eac3to. Individually they all play fine.

Gspot info on the source files is as follows:
File Type: Wave(.wav)
Mime Type: audio/wav
Codec: PCM Audio
48000Hz 1152 kb/s 1 channel

I have also tried creating the extensible wave audio file from eac3to by selecting wav as the output format. This creates an identical extensible file except in a wav container instead of an avi container. This file also gives the same error and will not play in wmp or windows encoder.

Seems problems with your DirectShow system config. The files seems ok.

If you have ffdshow, and set Audio Decoder -> Codecs -> Uncompressed -> All supported, maybe you can play the file in GSpot or GrphEdit (Avi Splitter -> ffdshow Audio Decoder).

I can't help you with Windows Media Player or Encoder. I don't use these tools.

Presumably if graphedit could render it, then wmp and encoder would also handle it. So if you can help getting graphedit to play it that would be great. As it is, graphedit reports that it is unable to find the necessary filters when I try to render the file. If I manually select the file source (Async) filter and load the avi, it can handle that. If I then render the pin, it connects to the Nero MP4 splitter and it will play. However it will not connnect to the AVI splitter. I think this is the source of the problem. I need directshow to be able to automatically render the file and its substreams.

Here play in GraphEdit with Avi Spliter/Nero Spliter -> ffdshow

Won't work in graphedit. I created a small sample audio.avi file with Microsoft's mono to multichannel (Wavavimux) tools. It displays the same error as my project file. I followed all directions on using the wavavimux tool and according to Microsoft this multichannel avi should be readily accepted by windows media encoder to create a 7.1 channel wma pro file. I would like to know if others are able to load this in wmp, windows encoder, or graphedit.

No problem with your sample in GraphEdit, Media Player Classic and AviSynth DirectShowSource().
Can't test WMP or WME.

Plays back works on Vista 32 sp1 WMP.
Didn't have time to test in windows encoder, or graphedit.

Edited: Tested in graphedit..working

okay, so I must have the same problem with directshow on two of my computers . I am assuming the problem is with the avisplitter. Any ideas how to restore this filter?
