Windows 7: Weird sound issue in DP35DP mobo

Thanks for the replies =)

Well, I gotta thank fireberd, patrickt and torrentg for their responses. Giving me the brief history of sigmatel audio was nice AND now im reassured that someone with windows 7 x64 is having no problems with this board so i guess the sound drivers are alright.

It might be poor power as torrentg mentioned which maybe is causing problems because the source which i plugin the PC power is using an extention and I connect both the monitor, cpu and the modem which could maybe cause interference. Darn, I never thought of that so torrentg has my thanks and I'll try to move the cpu to another power source in the house, as for the touching part, it had no affect and the sound is not constant. It comes only from using internet applications which I think the modem is causing due to the same connection line I use for both the cpu and modem.

Thanks again and I'll try to experiment with the power and come back later to say if the issue is resolved or not.

Also, my home is full of computers like maybe 5 of them are new and work fine with no issues on other power sources in the home so I guess I'll try to get the cpu in my dad's room and see if i still have the problem.

Be right back in a few minutes!

Bad luck

No luck, tried another power source w/o the modem and still have the same high pitch sound coming from the cpu and headphones .

I really need help here, I've got a few clues to where it comes from, I tried keeping my ear near the psu and heard nothing coming from it except the fan whizzing and got to the processor - no sound except fan, videocard - faint sound, got down and heard it very clearly. As i mentioned in the first post, the videocard is alright and i tried another old pci videocard from nvidia and the problem was still there so I took off the card and found the beeper near the soundchip which i strongly think might be the cause.

It or the PSU but for the psu i used another old 300w psu and still had the same issue. So, it might be a board problem which is the beeper and the onboard soundchip is very near to it and maybe causing an interface which i hear in the headphones clearly.

Im really frustrated and tired on this problem and it got me a full month to figure out what is causing it and i fail to find it. Right now, in summary, the problem might be from the board but in windows vista i hear no such thing. It's gotten real weird and I'll be glad if someone gives me a valid solution or if im not clear about the problem i'll gladly answer the questions.

Thanks.

It's up to me now..

I've done all of them already and still have this darn issue. Well, I guess It's all up to me now.

This issue is very weird and I'll try to get to the hardware components and check carefully each one of them, which, I hope will find the culprit or maybe get it to a technician to make sure the board is okay.

So, I thank all of you guys to help me in this problem and have been very co-operative in solving this issue and due to this issue going into a high-level hardware problem it's impossible to solve by altering the software so i guess that's pretty much it.

Thanks again for all your responses to this thread i started which is my very first one in this forum. Wish me good luck!!

Man what the hell?

Okay, I take that post back. For some weird reason, when i removed one of the RAMs the sound stopped, I don't know that what happened but one thing for sure is that there is a problem with the motherboard as I'm using a pair of identical kingston 800mhz 2gb RAMs with a timing of 6-6-6-18.

Very less often I hear the sound after the removal and there has been some performance gain for a weird reason, Can somebody explain what is going on in this board?

Thanks

PCI Simple Comm.Controller and Sigmatel/IDT Audio

I was surprised to learn that Intel indicated that the DP35DPM board is Window 7 compliant. Intel neglected to post a driver for the "IDT audio" chipset and for the "PCI Simple Communications Controller". Here is a trick and it will work, provided you have the original disc that came with your board. Place the disc in the drive, then enter your device manager. Look for the "PCI Simple Communication Controller", right click, and choose "Update Driver". Set it to browse the drive where the disc has been inserted. If memory serves me correctly, these drivers are also included in the "Intel Desktop Utilities" program as well.

In reference to the default audio driver that is included in Windows 7, does absolutely nothing but provides sound. The reason for this, what I call screw up is because they are eliminating the "Stereo Mix" feature. Why you ask, because apparently some people are making digital recordings and selling them for profit and naturally this violates copywrite laws and goes against RIAA. So the only way to get this feature back is to either revert back to XP or Vista? No, you can have it in 7 as well. Download the driver from the Intel site for Windows Vista. Click on the auto exec file. It will ask you where you want to extract files, usually the c: drive. Instead, choose to download those files to your "Download" folder. After that, you stop the install. Go into your device manager, choose the "High Definition Audio". Right click on it, and and choose "Update Driver". Again, browse for the file, located in the "Download" folder. Once installed, reboot. After reboot, the IDT control panel will pop up. Do not attempt to change any settings in the IDT control panel. Instead, click the "Hardware and Sound" in the Windows control panel/ and select "Sound". Make you adjustments there. The IDT control panel is good for volume settings and turning Dolby Digital on and off. Now I did this prior to the installation of the SP1.

I have spoken to legal represtation on how Intel neglected fullfilled their part of the obligation in reference to this particular product. Trust me, I will keep you posted on the outcome.

The DP35DP is an "old" motherboard that came out before Vista. But, it works with Vista and the Vista drivers so it will also work with Win 7 (I have Win 7 64 bit installed on my DP35DP). This is just about the end of it though, for my recording studio applications. I'll be upgrading to an i7 capable board early next year.

This Intel board apparently is made by Foxconn (who also makes some Apple hardware and some Dell motherboards). The first DP35DP I had went bad during the warranty period and Intel replaced it with a new board and the blank in the CPU socket has "Foxconn" on it.

Let have a history lesson. Since I was a beta testor for Vista and that was back in 2005, the final release was supposidly to hit retail shelves in the month of November, 2006 before the Christmas rush. But for some reason there was a delay, and hit the shelves on January 30, 2007.

The Intel DP35DP in reality designed for Windows Vista 32/64 version. The first BIOS release was on 05/30/2007, and the version was 0216.

Back in 2005, I built a system using a MSI_865PE_Neo2 board with a Realtek audio chipset. I currently have Vista on that machine. It works really well, and Realtek released a driver that has no limitations as far as the "Stereo Mix" feature. To be honest, I'm hesitant in purchasing a board that is going to have limitations. I've read quite a few reviews were people are upset because of this feature being elminiated. It places a damper on ones' creativity.

I too had an issue with my first DP35DPM board. The NIC chipset malfunctioned, and luckily it was under warranty, so they replaced it. Don't you think it's odd for a board that at the time, was only a year old and the NIC went bad??? Makes you wonder if you should buy an Intel board.
