Hi!
At first :=) very nice work done with this player :=)
works great, plays everything hardly

I have a 7.1 Surround System and like to see movies and serie with ac3 surround sound.
My windows configuration is: 7.1 Surround Sound

The "problem": VLC doesn't recognize that i have a 7.1 sound system and so the active audio output for ac3 files is "Stereo"
It would be very, very great if it would be like that: when there are more "boxes/speakers" than 5.1 (example 7.1, like mine) make 5.1 default.

Because if you change your settings in windows to 5.1 VLC does recognize that you have a 5.1 system, and also enables 5.1 surround sound in the movie (ac3 sound).
There has to be a small if statement somewhere in the code ;=)

Thanks for a nice free player!
keep on doing such great work

greets,

My educated guess is that DSSPEAKER_5POINT1 is in VLC, but DSSPEAKER_7POINT1 isn't =)
So adding
#define DSSPEAKER_7POINT1 0x00000007
to modules/audio_output/directx.c might do the trick.

Also DSSPEAKER_DIRECTOUT is missing... anything to do with bad SPDIF support?
#define DSSPEAKER_DIRECTOUT 0x00000000

What about providing a patch ?

If you refer to me, I don't have 5.1 or 7.1 output for testing the patch nor compiling environment to set up for the job =)

Now I have compiling environment but not the equipment, so if someone has 7.1 output and wants to try playback multichannel audio http://www.megaupload.com/?d=Q7XDY59B there is 0.9.0 build which should work better. Please report any findings to this thread.

I tried playback with 0.9.0 and the default is still Stereo and not 5.1.

I have the same problem.
Even if I make a playlist and set all mediafiles manually to 5.1 and if i switch the files in playlist, the setting on audiodevice is gone to Stereo instead of keeping 5.1.
Manual setting to 5.1 works of course, but if you play the next file or restart the player, the device is changed to Stereo.
This is very annoying, if you lay in bad, watching your favorites mediafiles and u have to stand up for every playlistentry...

System
Vista 64
X-Fi
Windows-Settings on 7.1
Creative-Settings on 7.1
VLC 0.8.6e and tested with 0.9.0

Greetins and thanks

p.s. is there a possibility to add #define DSSPEAKER_7POINT1 0x00000007 to any configurationfile (binary version, not the sourcefiles, i'm not a developer ?

It (DSSPEAKER_7POINT1) is a sourcecode level thing. dany_be: could you open View -> Messages before playback, open some audio file and see if log displays aout_directx debug: device supports lines, paste those lines here, please.

0.8.6e
aout_directx debug: device supports 5.1 channels
aout_directx debug: device supports 4 channels
aout_directx debug: device supports 2 channels
aout_directx debug: device supports 1 channel

0.9.0.
aout_directx debug: device supports 5.1 channels
aout_directx debug: device supports 4 channels
aout_directx debug: device supports 2 channels
aout_directx debug: device supports 1 channel
I played a mediafile with Dolby Surround today and there was the default on Dolby Surround an not Stereo *confused*

There might be an issue with dwChannelMask. I will check it out on friday and paste a new build if you want to test it.

thanks a lot, i will help where i can
(don´t know, if this idiom makes in english any sense ^^)

I totally forgot VLC_VAR_SETDEFAULT and GetSpeakerConfig. My bad (so my previous post is wrong). I have now new build which won't set Stereo as default if there are 5.1 or 7.1 sounds (unless SpeakerConfig defaults to stereo) and it will also tell what Windows tells about SpeakerConfig. So if it still defaults to Stereo, please check the log for line Windows says your SpeakerConfig is and see if it identifies you setup correctly. I could add option to override setup given by Windows if people want/need it.

the log doesn´t tell, what "Windows says your SpeakerConfig is" on verbose level 2.
with directx output it still doesn´t work.

i figured out, if i change audio output from directx to Win32 waveout extension it works and standard audio device is 5.1 if available
works with your new version and also with the old ones.

do i have any disadvantage choosing wav32 instead directx?

Little higher CPU usage with Waveout usually, but difference is very small.

Great!

so many thx for your help!

This has been bugging me for ages. I actually resorted to just setting my entire system to 5.1 permanently and had 2 speakers doing nothing. Now I can use all 7 again! So thanks heaps for this.
