Dell :: S-XPS 1640 And 1645 Audio Buzzing/cracking/distortion 60-80%+ Volume (to Bill For Engineers)

Feb 19, 2010

You can hear this effect around 60%-80%+ volume(varies by system) usually from the right speaker(more noticeable). It sounds like a speaker when its damaged from high volume or a bad amp you hear a buzzing/cracking/distortion sound on the right speaker usually(you can also verify it with the dell audio diagnostic, test my Dell technician even realized it). Ive had 3 xps's replaced(due to other issues) all of them had the same problem (additionally I had 2 speaker replacements and they had the same problem). sxps 1640 and 1645. I remember when a technician came and opened my motherboard I took a look at the side speakers. It seems that the right speakers are loose compared to the left ones. You can press on it and it goes a bit in and out.

I just wanted to start a new thread for Bill to bring this issue also to the attention of the engineers. I think I know what the problem is, I will be putting rubber pads in my laptop to enforce the speakers from vibrating. Someone brought this solution to my attention a long time ago.

Reference:

Post number 10(Metroline solution): http://en.community.dell.com/forums/t/19258055.aspx

Does anyone else have this problem? Verify so Bill can bring it to the attention of the engineers. Bills going to have big meeting with big players soon so post up if you do have this issue so he can bring it to the table. I didn't want to use the throttling thread for this issue.

My temporary solution is not to go about 60% volume... since it's load already but it would be nice to blast the volume and listen to music while doing other chores in the house or hang with friends but the audio quality is terrible.

Note: I can not verify this for sxps 1647 because I do not have one.

I will give you guys an update on my results, when I dampen the system with pads and reinforce it.

Dell :: Studio XPS 1640 Sound Cracking/popping

May 17, 2010

I don't remember when it started but my sound cracks and pops when I play games (NBA 2K10, WoW...) and sometimes when I'm watching youtube videos. However, it's fine when I just play a song on iTunes. Well actually, it pops a bit when I first start the song, but then the popping disappears, which leads me to think that the problem is somehow related to CPU/GPU usage.

So I've been on the web for quite a while now trying to find solutions...and here's what I've tried:

1) Using headphones (sound pops in headphones as well)

2) Turning off the wireless adapter (sound still pops with wireless off)

3) Disabling all enhancements under "playback devices" (still pops)

4) Checking IDE ATA/ATAPI controllers for Ultra DMA mode (got 4 ATA Channels, ATA Channel 0 is in Ultra DMA Mode 6, ATA Channel 1 is in Ultra DMA Mode 5, ATA Channels 4 and 5 are not in any mode)

5) Updating IDT High Definition Audio driver (updated, still pops; read somewhere that rolling back the driver would solve the problem, but at that point I've already reinstalled a newer IDT HD audio driver, which means I can't roll back to the desired date...)

6) Tried using a different HD audio driver (tried downloading a realtek HD audio driver, but I guess realtek = IDT?? same problem occurred)

6a) Eventually found some HD audio driver for some HP laptop (driver is now called High Definition Audio Device (under device manager => sound, video and game controllers))(sound still pops)

Specs:
OS: Windows 7 Home Premium 32-bit (6.1, Build 7600)
Processor: Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40Ghz (2 CPUs), ~2.4Ghz
Memory: 4096RAM
Graphics: ATI Mobility Radeon HD 4670
Bought: Around July/August 2009

Acer :: Audio Distortion In 6930G

Jan 23, 2010

I have this strange audio issue, that started when I upgraded to Windows 7.

When my speaker configuration is set to Built-in Speakers, I will intermitently get a hard buzzing distorted noise coming from my right speaker. It mostly occurs when I'm doing something, (browseing the net, navigating through explorer etc). Its stops on its own eventually, but sometimes can last a long time.

Heres what I know so far.
-The strange thing is that there is no distortion with headphones, its only the built in speaker.

-The problem is intermitent and does not occur in 5.1 mode, so its not a physical problem with the speaker, it must be software/driver related.

-I have the latest RealTek Drivers from Acer.

-The problem does not occur when my speaker configuration is set to 5.1 output.

Sony :: VAIO S Audio Clipping/distortion

Apr 21, 2010

I have recently purchased a new i5 vaio S from bestbuy. the first one that I got had a squeaky keyboard so I returned it for another. Both of these brand new computers audio randomly glitch out after about 20ish minutes of listening to music. This happens with both headphones and using the laptop speakers. I can only describe the sound as if you tazer'd a robot... its the weridest noise I have heard and only last for a second and then music continues to play. This happens with music on my computer, youtube videos, ect...

HP 15-d035dx Audio :: Sound Distortion And Overheating With Notebook

Aug 12, 2014

I have an HP 15-d035dx Notebook PC.
 
Lately I've been having issues with the sound, which I believe to be temperature related and I wasn't sure whether to put this in the audio or hardware board. 
 
Anyway, at least once a day I have to restart because any sound output-- videos, skype calls, music-- beging to stutter severely and sound how I can only describe as "robotic." After restarting, it goes back to normal. There are no error messages, the system just begins to lag and affected programs become unresponsive. 
 
Usually when this happens, I notice that my device is unusually hot. Ever since I purchased it, I have never heard or felt air moving in the vents so I'm not sure if the fan is functional. I'm afraid to take it apart to make sure in case that voids the warranty, but I suspect excessive heat might be damaging the components related to this issue.
 
The default sound device is  Realtek High Definition Audio

Lenovo ThinkPad L R/SL :: L420 / Windows 8 64bit - Audio Playback Jitter / Distortion On Battery Or Charging

Jan 11, 2013

So this is about the only issue I have with Windows8 on my laptop, I've tried various audio drivers from OEM provided
to drivers directly from the Realtek site and I can't seem to remedy the issue....
 
Only during charging of my laptop or when the laptop is on battery does the jittery/distorted audio playback occur. Happens during Flash playback or local media playback using say VLC, sometimes the distortion can Freeze or lock up the system.....
 
I've tried Audio Drivers, Video and my BIOS is the latest. This playback issue did not occur under Windows7 when I had it installed....

Dell :: 1640 With A 1645 Motherboard

Feb 20, 2010

I was on chat with dell a few months back and I was telling them to replace my motherboard and processor and I was complaining about heat.

Anyway during the whole convo I was joking (not really) about giving me a 4670 motherboard instead of the 3670. Well I have had the parts for a month now and was just going to return them because

I didn't feel it would change anything replacing the same parts, knowing that the xps just gets warm on it's own. (and yes I undervolted, helped a lot and added more thermal paste)

Any to make a long story short the dell tech sent me a motherboard now with a 4670 ati chip on it. The processor was the same but man am I stoked.

Anyway is my computer a 1640 still or a 1645. Should I update any other drivers besides the video card. My service tag is irrelevant now also when downloading drivers.

Dell :: 1640, 1645, Or 1647

May 27, 2010

I've decided to get an xps 16 for college, and I am curious as to which to get. I plan on using it for college, but also plan on playing quite a few games on it as well when I have the time. Which would be better overall to avoid throttling issues, and just have the best performance for this overall?

On a side note, on the dell site, how do I tell which is a 1640, 1645, and 1647?

Dell :: S-XPS 1640 And 1645 Bottom Line!

Feb 3, 2010

The bottom line is that this laptops are not worthy to buy!

1. Throttling Issue (No real fix so far)
2. Random freezing (Speculations about driver fix)
3. Brightness control stops working randomly (remove batery to fix)
4. Sub-buffer rattles (nobody knows why)
5. Stereo leaks between left and right (no fix)
6. System runs extremely hot (1645 a little bit less than 1640)

All-in-all nice looking and feature complete laptop with a lot of issues.

Dell :: XPS 1640/1645/1647 Heat Vent

Feb 17, 2010

So yes I have no cred and I am relatively new but I think we can all agree the direction of the heat vent on the XPS 16XX series needs to be changed to face downwards at least, so that the heat isn't dicipated directly onto the screen!

There doesn't seem anywhere available to add a secondary vent, so at least the primary vent needs to be improved.

I will send this to Dell_Bill_B as he requested in the throttling forum, and he said he would take this issue up at the next conference call!

Dell :: Should We Start An Official 1640/1645 And Windows 7 Thread?

Oct 19, 2009

What does everyone think about starting a dedicated thread for the XPS 1640 (and 1645?) with Windows 7? ("Official 1640/1645 and Windows 7 Thread")

I think starting now, there will be a flurry of driver updates, behaviors, tips, questions, etc.,

and it seems it would benefit everyone to have all those in one place instead of having to search through a myriad of individual posts

Dell :: Studio XPS 1640 1645 Serial Flash CMOS PINS

Apr 4, 2010

Dell Studio XPS 1640 1645 Serial Flash CMOS PINS

The process to be used appears credibly outlined at the following web address: http://www.darkmagic.org/mike/dell-tag/dell/dell.html

But the laptop used in the above web site is not that of a Dell Studio XPS 1640 or 1645. So parts location, disassembly and reassembly are unique with the 1640 & 1645.

I have had the 'privilege' to be stonewalled by Dell 'customer service' when requesting the lost password to access CMOS & BIOS setup on my Dell Studio XPS 1640.

I purchased a used Studio XPS 1640 that was just under 2 months out of warranty from another who was disgusted with the hassles that have developed with some of the 1640s & 1645s over heat, throttling, RGB screen blinking, inadequate power supply, etc, etc. The formal transfer of ownership was immediately completed on Dell's web-site .....

HP Envy 15-j004sa Audio :: Max Volume Is Very Limited

Jan 23, 2014

I have a HP ENVY TS 15-j004sa Notebook PC running windows 8.1with Beats Audio Under normal circumstances, listening to music or films close up with no other sounds around, the volume is not a problem. But, if i need to raise the volume either because i am further away or because there is some other distracting sound, I find myself very limited in how much i can raise the sound - and i am not talking about trying to get an ear splitting volume.
 
This is true even if i have everything at max: the Windows 8.1 Settings volume, the volume control on the task bar of the desktop and the volume control on the application.Is there anything i can do to give more flexibility to the volume?

HP Pavilion DV7-1261wm Audio :: Windows Volume Control

I have turned off my built-in microphone. I had to unistall my HP SmartMenu controls because the buttons wouldn't respond and the on-screen volume display would activate every time the windows volume control would move causing me not to be able to play any games. I have ran MSE and MalwareBytes and have not found any viruses or ad/spyware that is causing the trouble. I don't' know what to do..I really don't want to have to go through the process of windows re-install or game re-installing.

HP Pavilion Dv6 Audio :: Laptop Volume Is Very Low Even With Setting At Maximum

Aug 15, 2012

I have tried every setting available on this laptop, from all set to default to trying multiple changes in all the settings. The volume is consistently low and has a very annoying reverb and echo effect, even with those settings turned off. I have only had it for a week, and I have been very pleased with everything else accept the audio. The reason for purchasing this model was for multi-media processing and so far I and becoming more disgusted daily with it. It is a Pavilion dv6 and it has the beat audio software.

Lenovo X Series ThinkPad :: X220 Low Volume Audio

Mar 13, 2011

Even cranked all the way up, the sound on the x220 seems somewhere around half as loud as the x120e and even my wife's iPad blows it away.  It's a litle embarrassing.
 
I think it's the sound card/driver not the speakers as even with headphones plugged in it is very very soft at 100% volume.
