Problem with 5.1 Sound - Again...



I posted in posted in Q: http://www.experts-exchange.com/Hardware/Q_21195722.html before.

Since I thought the problem was not having used the correct cable setting, I accepted a solution there, but then I fixed that and it didn't solve the problem.

I have a Fujitsu-Siemans Scaleo T, with SigmaTel Soundcard, in system it’s called SigmaTel C-Major Audio.

I’ve connected all cables correctly. The sound is set to 5.1. Also in the SigmaTel Jack Sharing, speaker configuration is set to 5.1 surround sound and the right part of the meny show the mapping of the ports to the 5.1 sound (not possible to affect)

I’ve tried a couple of DVD:s, on some I don’t hear anything at all, at other I get stereo-sound in left and right frontspeaker.

Any ideas?

I think the problem is simpler that what it is looks like, Did you see your speakers settings?

Hi, it's me again, the guy who you gave the points to last time, lol.

Now that you have sorted out all the cables and checked that they are in the right places, you need to change the speaker setup once playing the DVD. For example, when you put the DVD into the drive and your media player starts playing the dvd, you will be taken to the standard DVD menu (where you choose to view special features or play the movie, etc) usually, there is an option called something like Audio setup, go on this and ensure it is set to Surround sound (5.1/DTS/Dolby 5.1, etc) usually, this is defaultly set to Stereo sound for playing in the average TV.

If you cannot find the Audio setup menu, start the DVD playing like normal (the actual movie) and right click on the screen, then you should be able to go to something like Audio setiings, then it will say English1, English2, etc, just go through these until you hear surround sound. Good luck

Cyber-Dude: Speakers settings (under sound - advanced) is set to 5.1

kinobestew123: DD5.1 I already set... I had a 5.1 DVD player before, which I'm trying to replace with the computer.  

I have all the latest updates and I've tried 3 different Mediaplayers (one of them being WinDVD 5.1 included in the CD-package of the computer).

I crosschecked that all the channels on the receiver are working

In the forum of fujitsu-siemens, other people having had the same problem, says it depends on the DVD-player, that it need to be a 5.1, but as I said, I've tried the WinDVD 5.1, which is guaranteed to play 5.1.

Since I did these changes, I get 2 channels (Front left-right), but the other 3 (satellite/center) are still dead...

Any more ideas? I called the support and they have no clue, so I will send it in for hardware check. I just want to make completely sure that I've tried all options, in order not to have to pay for false alarm...

cheers,

henrik

I assume you've checked to be certain that all 6 channels are being recieved at the reciever.  Make sure you have SPDIF output turned OFF.  (You're using the soundcard to process the AC3 information instead of sending the single SPDIF signal to your amplifier.)  By the way, your reciever is what was known as a "5.1 ready" reciever, not a true 5.1 reciever.  It lacks the processor needed to convert the digital information into audio signals, which is why you had to go purchase the cables.  There was one alternative solution not mentioned before: you could also have picked up a dedicated converter to sit between your computer and amplifer.  This is what I have, and it's nice to only have one cable between the computer and amplifer.  The down side is it's expensive unless you can find a "steal of a deal" on eBay, but sometimes these units can be had for very little.  (As an example of one, see this SH-AC3000 on ebay.  It includes an amplifier which you don't need, unforunately.  http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=14981&item=5734840754&rd=1&ssPageName=WDVW )

At any rate, all you have left to do is get your software to put the audio into the right place.  Go into the options screen for your player, select the audio tab, and choose some 5.1 configuration that doesn't mention SPDIF.  For instance, in PowerDVD, set the speaker environment to "Using 5.1 speakers".

You may want to uninstall all of the DVD software that you've installed over the weeks trying to get this to work.  Sometimes these packages walk over one another and can cause problems.  My personal choice for best player is PowerDVD -- it seems to produce the best result and has been the most stable fore me.

If you find you are still having problems, you may wish to try an alternative aproach.  There is a free package called "AC3Filter" which will decode AC3 information and send it anywhere you want.  It's a great piece of software, but there's a catch:  You have to get it installed right.  You can find it at http://ac3filter.sourceforge.net/ but I wouldn't recommend going down this path unless you've really tried everything else first.  On the other hand, this method WILL work if set up properly -- it's a bit like using a sledgehammer to drive a thumbtack.  In order to use AC3Filter, however, your player must use that filter over its own internal filter.  Some players will let you do this; others complain.  The best players to use are those which let you choose a software and video decoder to use, such as the shareware package "Zoom Video".

Good luck!

ok, im kinda running out of ideas now but maybe (just maybe) the problem is with your DVD drive (in your computer), i've never heard of this before but it could be that your DVD drive is sending the signal down that wire that you connect to your motherboard (the audio one), my reasoning behind this is that wire only has two wires, now I dont know much about electronics but these two wires I presume are left and right (hence, the stereo sound you are getting). Once again, i'm not sure if this is possible, but it may be possible to have the sound sent down the IDE cable so that it is surround sound but you would have to research this, maybe if you unplugged the audio cable from your drive this would automatically do it but im not sure anymore.

Good Luck!

OK guys, I've tried your suggestions and it didn't work. The support is coming to pick up the computer today, so if they find an hardware-error you'll get points, if it's a software-thing you didn't advice me on and I have to pay the support for false alarm,  I'll have EE deduct points from you ;-)

cheers,

The sound still doesn't work. Now Fujitsu-Siemens have promised to send me some audiofiles, I'll install them and if it doesn't work after that, I'll have to back the computer again... *sigh*...
