Multichannel audio WMP 9.0 in Windows2K

[Hippo]

Hello,

How to get 5.1 multichannel audio output for WMV files in Windows Media Player 9.0 running Windows2000. According to Microsoft multichannel option is limited to work only in combination with Windows XP and does not work with older MS operating systems. Indeed in Windows2000 the "advanced" option for selecting the speaker setup in WMP 9 is missing to start with.
Is this a correct observation and if so is there an alternative solution to get 5.1 surround sound working in WMP 9 using Windows2000 ?

use aac for encoding multichannel files (it is already possible with besweet and neros aac codec)

btw in contrary to wma decoding aac should work on all major systems (mac, linux), not only in m$ products

[Hippo]

But what's the next thing to do in case the WMV file in question is already in decoded form, e.g. for the WMV HD (High Definition) demo examples present on the Microsoft website ?

bad luck :(

@Hippo:

Did you try another player than WMP 9 yet? If I remember correctly Gabest's MPC played the full 6 channel of my files. I can't check right now, because I have the file, but no Windows 2000 installed.

Thanks for the replies.
Since putting my question on the forum I already tried other things.

First observation is that surround sound from a single 6-channel WAV soundfile (6 channels of uncompressed 16 bit WAV) plays correctly over six channels on my Windows 2000 computer in combination with a RME Digiface card & digital Dynaudio loudspeakers. So the hardware is in principle well capable of playing 5.1 surround soundfiles.

Programs that work correctly in this way are: Winamp2.81 and Cooledit Pro 2.1. In contrast, the installed Windows Media Player 9.0 player (including Media Player Classic 6.4) don't recognize multichannel WAV format and stay completely silent trying to play back these soundfiles. The other way around is unfortunately also true, Winamp cannot deal with multichannel wma or wmv formats, whereas Cooledit Pro 2.1 automatically translates multichannel wma files to stereo files.

Second observation is that imported surround wmv or wma formats refuses to give any multichannel sound using the new Windows Media 9.0 player. I'll tried many things like installing the Windows Media Encoder 9.0 package. Alternatively I installed dBPowerAMP Music Converter including its special WMV 9 encoder plugin, but nothing seems to work. In essence, the WMP program merely sees multichannel wmv audio as stereo files.

E.g. the "file properties" tab in the Windows Media Encoder program correctly indicate that there is a six-channel input file, but after encoding you only end up with a folded downmix stereo soundfile. If one choose another output audio format than stereo, such as 5.1 channel formats via the selected Windows Media Audio 9 Pro Encoder, the Encoder gives the error message "The input media is invalid (0xC00D0BB8)" and WME stops doing the conversion. The WMP9 manual clearly states that the error mesage is caused by not running WindowsXP or that incompatible file formats are involved.

Interestingly, the dBPowerAMP Music Conversion program seems to convert genuine wmv and wma multichannel to uncompressed audio without any errors, however it turns out that the output 6-channel WAV file after conversion does not really contain six independent audio channels. In fact, the single WAV file contains three identical stereo pairs representating the same stereo downmix as found for the Windows Media Player 9.0 playback.

The suggestion to use the Gabest MPC player I have not tried yet, it seems that the website gabest.org is currently under construction and can not be reached.

So my conclusion is that somehow Microsoft must have placed a software restriction in the multichannel capabilities of the Windows Media Player under Windows2000. Possibly done deliberately with the idea to get rid off support for the older Windows OS.

It is further interesting to note that I have carried out a file comparison between the XP and Windows2000/Windows98 installation package of the WMP 9.0.It turns out that these downloadable and self-extractable WMP 9.0 packages MSsetupXP.exe and MSsetup.exe (W2K) do not reveal any significant difference in file content. The Windows2000/W98 version of the package contain exactly the same .dll & .exe files, with the exception of some extra Windows98 file code and of a few *.cat files containing different header and footer texts. A binary file comparison between the XP and W2K package really proves that the essential files are 100% identical.

My suspicion is that both the encoder and decoder routines of WMP 9.0 simply looks for specific keys in the registry database to see what version of Windows is running. In case this is not a XP version, it is highly likely that certain restrictions are put in place in the Windows Media Player software or other external WMV en-/decoders.

Any suggestion if this sounds reasonably, and in case it is true what registry keys are involved ? Final important question: has anyone succesfully decoded multichannel wmv files on Windows XP to see that it really can work ?

Microsoft states clearly in the help files of Windows Media Encoder that WMA 9 Pro 5.1 will automatically be downmixed to 2.0 when not running Windows XP. The question is where this restriction is hidden. Either in the Windows Media Player software or in the codec itself. If the latter is the case then I think you are quite lost.
Fiddling with the registry and trying simulate an OS that isn't there will surely get you into serious trouble. First, I think that the information about the OS running is hidden multiple times in the registry and other places. Second, other programs might use this information as well.

Winamp does not support WMA 9 Pro. You can try to use foobar2000 (http://www.foobar2000.org), an unique audio player. Media Player Classic can be found on Gabest's Sourceforge page (http://www.sf.net/projects/guliverkli). Please do me the favour and have a try. I can't really afford to install Windows 2000 these days to test it myself.

Hello again,

I've tried both the MPC Gabets player version 6.4.7.6 and the foobar2000 player version 0.77 on some test WMA's, and although both players are able to play wma files, none of the programs outputs wma files in multi-channel sound. However, the MPC player has some nice features to select and block DirectShow filters yourself. Here it follows that the most likely culprit of the problem lies in the "WMaudio decoder DMO" and "WMAudio encoder DMO" DirectShow filters installed by WMP9. According to the Windows2000 registry the output types for the decoder and the input types for the encoder (and therefore the number of audio channels) seems to be limited by means of registry keys. At least it looks like that.

Before changing these values manually the hard way, can someone who installed Windows Media Player 9.0 & Windows Media Encoder on a Windows XP computer, please report what is mentioned under binary keys containing the search words "WMAudio Decoder DMO" and "WMaudio Encoder DMO". It would be interesting to see if the content under the following keys differs between Windows XP and Windows 2000.

Hope you figure someting out but just by glancing at the numbers both 2000 and xp seem to be the same.

My thoughts are a bit different on this issue. I don't think it's a registry issue at all but an issue with the structure of DirectShow. There are differences between the capabilities of DirectX for XP and the other version of windows (remember that DirectShow is considered part of DirectX). What microsoft has most likely done is added 6 channel wave support to DirectShow, in essence re-written how channels are supported in wave streams by adding 4 more channels.

I remember reading something about this in the DXSDK...

can't find it in the dxsdk, wonder where i read it?

There were issues in the handling of multichannel audio, but they were fixed by a hotfix for Windows 98 SE and in Windows 2000 SP2 AFAIK. Thoses fixes are included in Windows ME and Windows XP.

One can play multichannel audio on all of those OS's whether AC3, AAC, RA (Cook) or Vorbis. So I think it is a limitation by Microsoft to get XP selling. I didn't run through all those registry keys, but I'd rather guess that the limitation is in the codec itself.

What else should be the cause? Technically Windows 2000 and XP aren't so much different. Some things may have changed under the hood (handling of kernel drivers for example, support for HT and such stuff) but more or less XP is a GUI update to 2K. Otherwise Microsoft have a grown tired of supporting their various OS's over the years (drop for Win95 support with DirectX 8.1 because of "technical reasons", forcing people to upgrade to server 2003 by dropping NT and so on...).

Ah, make up your own thoughts about M$.

thats why i now recommend everyone to use aac if he/she want multichannel at low bitrates (or to wait for vorbis handling channel coupling) :D

[tiki4]

I do use AAC, while mostly not in MP4 ATM. I still haven't found much time to play around with your tools, bond. Maybe after finishing PhD. Otherwise, we are waiting for channel coupling in Vorbis for a long time now. There's a discussion on HA going on about Vorbis, but unfortunately it seems to have totally lost its topic.

Thanks Asmodian for reporting the registry information about the WMaudio Decoder DMO section in WindowsXP. Th resemblance of the keys indeed rules out differences in the registry file at this point between Windows2000 and XP.

After some research the codes of input and output types in WMAudio are universal sound formats and indicate the type of WMA coding scheme, and has nothing to do with the number of audiochannels.

On every third line, the second hex number stands for
01 = WAV PCM
60 = MSAUDIO1 (DIVX)
61 = WMaudioV2
62 = WMaudioV9
63 = WMaudio Lossless

Files important in the WMAudio conversion are wmadmod.dll and qasf.dll, installed by Windows Media Player 9.0. Strange thing is that these files are the same for Windows2000 and WindowXP. In fact, the setup files for Windows Media Player XP and Windows Media Player W2K/ME/W98 are in terms of DirectShow files bit-for-bit identical. However according the log file of the WMPsetup installation the WMP9 files named:
- wma9mod.dll
- wmv9mod.dll
- wms9dmod.dll
are expected during setup, subsequently not found and their entries deleted from the Windows2000 registry (see part of logfile below). Are these last three files maybe specific for XP ? Secondly, the important DirectShow and DirectMusic soundengine of Windows resides in Quartz.dll file. Any idea if this file is basically different in the last version of XP compared to Windows2000 ?

In: "C:\winnt\system32\quartz.dll" - Windows2000 (SP3) UK
30-05-03 09:00 1,962,496 quartz.dll

Regarding the multichannel WMA audio in Windows Media Player, in Windows2000 output is always downmixed to stereo. The inconsistent thing is that Microsoft has a free available command line program. WMAl2PCM.exe (also working on Windows2000 ofcourse), which allows conversion of a 6-channel lossles encoded wma file to a single WAV containing six discrete WAV channels. This type of conversion indeed works as a charmm. The unpacked WAV file created by WMAL2PCM plays with no problems over six audio channels, thereby circumventing DirectSound altogether. The other way around, from multichannel WAV to multichannel wma, can in principle be done by WME9, Cooledit Pro 2.1 or dBPowerAMP Music Conversion programs, but afterwards you still can not convert or play the soundfile in multichannel mode due to the fact that all these programs use the Windows DirectShow filters from Microsoft. Unfortunetaly, the corresponding command line program to convert lossy compressed WMA9Pro encoded wma files to uncompressed multichannel WAV is unfindable on the Microsoft site or the internet. Probably for some good licensing reasons, I don't know.

So, in the end Windows2000 users are forced to upgrade to WindowsXP to enable and get access to the new multimedia features, despite that under the hood the programs are virtually identical and that perhaps only a few Directshow and kmixer files need to be replaced by more recent XP versions. It's a pity.

Here is part of the log file during installation of WMP 9.0. Does not make any sense.
