Recently I've been having some problems playing back any sort of media. At regular intervals the audio will freeze/skip for a second and make a loud grinding noise, then resume. This happens with music, streaming videos, games, pretty much everything. If I'm watching a video or playing a game, the screen will freeze for a second, then resume.
I'm using an Inspiron 1545 with Windows 7 64-bit, SP1.
I've tried everything I could think of, updating all my drivers, reinstalling codecs, running anit-virus, and cleaning out my system. I've found that sometimes the lag corresponds to spikes in my DPC latency, but sometimes they don't, and I can't find out what's causing the spikes. I've tried most of the solutions here: http://en.community.dell.com/support-forums/laptop/f/3517/p/19142484/19265470.aspx#19265470 ,but nothing seems to have helped, and I'm getting a bit desperate.
Solved! Go to Solution.
I have a Dell Inspiron 1545 running Windows 7 Service Pack 1 with the exact same problem. It started recently...I would say within the last week. Whenever I listen to audio or watch video, an annoying buzzing sound occurs intermittently. It occurs when I play music CD's bought from a store, so it is not just a problem with streaming content. I've also tried virus scan and system cleanup. It hasn't helped. I even ran a diagnostic test of my audio system through Microsoft and no problems were found. I noticed another user with a screen name SuperBird reporting the same problem with their Dell Inspiron 1545 in the Dell forums yesterday too. I find it curious that three of us are having the exact same issue with the exact same laptop recently. There was suggestion to remove Dell Support Center, but I don't even have that installed so that couldn't be the problem. Let me know if you find the solution and I will do the same. Good luck.
That hasn't seemed to do anything.
I did see in my BIOS settings that I could switch my hard drive from ATA to AHCI. Could this make any difference?
Yep, it happens with any kind of media I try to play, even off of a disk. The only thing I could think of it being is some program or driver causing the spikes, but after extensive searching I still haven't found the culprit. I would say it's a hardware problem, but it seems kind of unlikely since so many people seem to be having this issue.
Oh well. I'll keep looking, and update this with what I can find.
Unfortunately, I haven't been able to find the solution after days of trying. I uninstalled some Windows Updates from last week, but that didn't help either. I've tried virus scans, system cleanups, uninstalling and reinstalling the audio driver, etc. At first, I thought this was just an audio problem, but I think it may go a bit deeper. I notice when watching videos, such as YouTube, that when the grinding/skipping sound occurs, the video also freezes. It would seem to me that if it were just an audio issue, the video would continue to play with no interruptions. I'm no techie by any stretch of the imagination, so I could be way off on that. My brother-in-law, who works with computers quite a bit, suggested I might have to do a factory system restore. I'm trying to avoid that route if possible, especially since I am very skeptical that it would even work and that if it did, it probably wouldn't last long. This is very odd. I haven't installed any new software recently nor does my computer have any viruses. The only change was the Windows Updates from last week, but obviously, that doesn't seem to be the issue either. This situation is getting very frustrating, as I know it is for you too.
Thank you for the update. I will continue to look into it as well and reply with anything I find.
I have been a A+ Technician for 22+ Yrs., and this has me baffled, We will figure this out together. We Can do it by troubleshooting, and eliminating things one by one. I did see on My "Dell Downloads & Drivers" Page. That Dell had released a Hotfix Patch for the Dell DataSafe, because it would cause skipping, stuttering is what the hotfix said, I tried that one, did not work. I have also been trying the other steps of elimination from: en.community.dell.com/.../19265470.aspx mentioned in this Post here: en.community.dell.com/.../19986557.aspx , I will keep working on it, and Together We Will beat this thing.... I will update ANY updates as I come across them. Thanks for inputting your information on here, We Can Do This...
