Solved 5.1 sound (AC3) in windows 7

[Yossi]

Hey guys
I wanted to ask about the sound in 5.1 mode
To date I have used windows xp and all kinds of viewing software such as VLC and BS and of course K LITE-coded and everything worked fine and very high quality

Yesterday installing windows 7 ultimate 32 bit and now I can not hear sound 5.1
I tried everything I installed my sound card to a modified version windows 7
And he works very well. And installed coded all types and still do not get 5.1 sound
Now what is strange is that when I went to the AC3 filter I see 5.1 indicator but it does not come out on into my receiver via optical port
Are you recognized the problem and what should I do?

 

[Britton30]

Modified Windows 7?

 

[Yossi]

I'm sorry I did not understand the question
I installed windows 7 ultimate 32 bit
And I installed all the drivers for my computer
Sound card video card driver and all other
And installed as usual BS PLAYER
And K LITE
No sound comes out 5.1

 

[Britton30]

I tried everything I installed my sound card to a modified version windows 7

this is what I meant.

 

[Yossi]

Yes I installed my sound card software that fits windows 7
My sound card is relatively old and its software suitable for older operating systems and not for windows 7
So I downloaded from the site of the sound card and appropriate software to the latest windows 7 and I installed it and still does not work for me
I see in the AC3 encoded indicator for indicator 5.1 is working
But do not get through the optical port on into the receiver

 

[Britton30]

If your optical out put is on your motherboard it is probably disabled since you installed a sound card. Can you get sound output from the mini pin sound jacks?
Manaually run a check for Windows updates to see if it will install a missing driver.

 

[Yossi]

Forgiveness may not have explained myself correctly
I bought a sound card with optical port, with which I use
I'm not talking about a sound card on the motherboard
Listen,,, I understand in computers ever since I solve every problem alone without help and technicians
The sound card works fine and encoded also seemed to work well I see when I start the software everything works
But somehow it does not convey the information and it happens only with windows 7
In conclusion I can see visually that everything works fine and I also hear the stereo sound
Only 5.1 not working
I use the K coded LITE They work great with WINDOWS XP I really hope we can find a solution will also work with 7

 

[Britton30]

Do you have 5 speakers, 1 bass and 4 surround which don't work? That's what 5.1 is.
Did you try Windows update?
What is meant that the sound card is encoded?

 

[Yossi]

How to explain this
I have a home theater system receiver that I have connected 5 speakers
Until recently everything worked fine I connected the computer via the sound card we are talking about this receiver and I saw MKV movies and all sorts of other movies and it worked great with WINDOWS XP
The day I installed Windows 7 does not work anymore
Now understand the problem?

 

[Britton30]

OK, it is clearer now. You have a sound card with an optical output, your receiver indicates it is getting 5.1 sound but does not play it with the optical output? this worked with this arrangement in XP and not 7?

Is there an adjustment you may need to change within the receiver to accept the optical signal?
I have also asked other Gurus for help and hopefully someone can help you.

Shalom Yossi.
Right click the speaker icon in the lower right corner. Select Playback. In the window that pops up, check to see if Digital Output is enabled and selected as Default.

 

[Yossi]

No you're wrong in what you understand
My receiver does not show me that he gets the information
I have indicator lights that show me when he's in stereo and when he goes into Dolby Digital 5.1
I said the software itself, I see 5.1 move parameters
But this is not the problem WR This essentially means that the computer does not send this information on Windows 7 for some reason

 

[Yossi]

Hi and hello to you too
I did it and the optical port and set to work properly
I get my receiver stereo sound like I have always received
But when I start a movie now or BLURAY MKV
Receiver does not make for Dolby Digital stereo is left in
In WINDOWS XP when I was running one of these films was immediately becomes the receiver to Dolby Digital and 5.1 sound telling me

 

[carwiz]

Two more screens to check.

The first screen is the Properties of the Optical output. Be sure the settings match your receiver.

The second screen is the Enhancement tab of the Properties. Check the box for Virtual Surround.

 

[Yossi]

I have a different sound card
My sound card is CMI8768 PCI connection
And is defined as ever it was set on optical port
Listen friends, I want to clarify something topical to enable you to help me in a more correct way
I understand computers very well and have lots of experience with them
And never had to get help or support I always get myself

The reason I tell you this
Is because I know the problem is not on the sound card and settings
Because for years I see movies that way and it works great
An interest is to dig about in connection with WINDOWS 7 is where the trouble
Instead of dealing with explaining to me about the sound card and encode all of these various
Try to understand there is a problem related to the fact that Windows 7 does not convey this information through my sound card
I hope that I will not bother you too much about that
I have no one to turn to except you
Thank you

So your configuration screens don't show similar options as pictured above?
As with any new release of Windows, various hardware devices may need new drivers to function properly. Information on your sound card indicates the only Windows 7 driver available is for the Windows 7 RC7600 (Release Candidate). The driver is dated 2011-11-24 and is version 8.17.40 however; the same version is listed for other sound card models with a date of 2010-02-09.

I suspect your problem is related to the driver and not Windows 7. I think the best course of action would be to deal with C-Media directly. They are the only one that can supply drivers for your card.

Here's a link to the C-Media driver download page: C-Media

If you already have driver version 8.17.40 (2011-11-24) then there must be a compatibility problem with the current Windows 7 OS and only C-Media can fix that. The only other option may be to update your sound card with one that is supported by Windows 7.

Sorry I couldn't be of more help to you.

Please plug in the exact brand and model number into the hardware tab. Windows 7 Compatibility: Software Programs & Hardware Devices: Find Updates, Drivers, & Downloads It may be too old to be compatible with Windows 7.

Hey friends
I wanted to inform you that I managed to fix the problem after hours of playing all the options
All he needed to do was make the analog outputs disabled
And become the default digital port and synchronize it with the sound card
So thank you all help me a lot. Kindest regards to you all
