After BIOS upgrade the SPDIF is not working, DQ77KB

Hello,

after I did a BIOS upgrade on a new board DQ77KB I noticed that the SPDIF via the 3.5mm jack is not working any more.

I've found a similar discussion the it only works with BIOS 0048 so if Intel reply on that it would be great as I don't want to downgrade the BIOS and need the S/PDIF to work.

Regards,

Alex

Hi alex1234,

I am sorry to hear you are having problems but let me help you.

I would like to verify more information about your system. Can you please post your dxdiag report here? Please make sure all drivers are updated to the latest (Graphics, Management Engine, BIOS, etc)

Also, can you please provide the steps you are taking to reproduce the problem or let us know what software are you using?

Hi Kevin,

I've already update all to latest version.

It's very simple to see the problem, as there is not red glow on the 3.5mm port.

here is the dsdiag:

alex1234,

Checking the DQ77KB board specifications, it does not have a header for the S/PDIF so I assume you are using this jack to convert the signal.

It is important to mention that the usage of the adapters/convertors is not supported and there may appear inconsistencies when using it.

I am going to send the feedback to the proper department for future considerations but in the meantime, if the previous BIOS version was working fine, I recommend you going back to the previous version while we check what the problem could be.

to support what alex says,

I could get it working only when downgraded to bios update 48, no luck with 49, 51, 52, 53

(you simply don't get that realtek digital output)

I think it is a disgrace that any BIOS after 0048 disables the TOSLINK.

Well, I don't know if this will help, but I have a DH87MC motherboard and I too had a similar problem. My computer case has a plug-in on the front for a headphones and microphone. There is a header on my board for these options. I was going through to update all the things available from Intel including the BIOS and the Realtek audio drivers. After I was finished I noticed I no longer had access to these plug-ins on the front. Mainly the headphones is what I was concerned with. So I backdated the BIOS till I was at the original and there was no change. So then I started with the Realtek audio driver updates and did the same thing. It only took me uninstalling the first update, which was the latest available, to realize that it was the audio driver update that was causing me to lose the headphone jack option in the sounds dialog box. Once I removed the Realtek update, Windows 7 64 Bit reverted back to the generic driver and I got the headphone jack back again in sound. So then I re updated the BIOS to the latest version and I still had the headphone option available. So my conclusion is that it is the Realtek audio driver that doesn't support the front plug-in for the headphones.

Well, apparently there are many ways to frustrate users. In my (actually OUR, I am not alone) case, the "Realtek Digital Output" appears (see last picture in previous post by ALIELO, above) only after you install the Realtek driver. I disappears when the BIOS is upgraded beyond 0048 and reappears when downgraded to 0048, without reinstallation of the driver. I can always see front and back analog outputs.

I am really sorry for the inconvenience. I will pass all this feedback to the corresponding department.
