Inspiron 1525 audio/wireless issue..

Hi everyone..

 

My Inspiron 1525 T5800 CH-07 came last Tuesday with only FreeDos cd (there wasn't an option to buy it with Windows). I installed XP SP2, downloaded Dell drivers, installed them in the exact order the instructions on Dell site say.. and was so sad to realise I had a problem: the audio cracks and pops every minute or so..

 

At first, I didn't know what it was, but a little bit of googling, and to my horror I found bunch of forum threads about this topic.. First thing I did, I disabled and deinstalled my wireless card - and hey, the sound is now perfect!

 

I have tried and tried almost any advice there is out there, including the ones at http://en.community.dell.com/forums/p/19142484/19265470.aspx#19265470

 

I tried installing the SP3, then went to Vista.. the sound improved a bit, but still you could hear those awfull cracks..

 

Then I tried installing ubuntu 8.10 - and it works flawlessly!! emoticon.Smile.title

 

But, as linux is not an option for me, regarding what programs I intend to use, I am back to Windows (and cracky audio).

 

I have contacted my dealer (here in Croatia we don't have the 21day money back..) who told me that they were familiar with this issue, and since it is a software bug due to lousy drivers, the warranty doesn't cover for it! The online store where I bought my Inspiron is very supportive though, they've offered me a lot of tips and tricks that might help, but still, no improvement.

 

They did say that if nothing else worked, they would take the laptop back and install a hdd drive with preinstalled windows and drivers. If that wouldn't work, there is possible (!?) solution of returnig the laptop alltogether and switching it for a new one..

 

My question is this: the ones of you who have had or are stil having this issue.. was your Inspiron delivered to you with preinstalled Windows, or did you do it yourself? In the former case then, the solution my dealers are offering me, won't actually help a lot..

 

Question number two, has anyone tried altering the IRQ numbers assigned, I have read about it on some forums (although it shouldn't be an issue nowadays, but still)? As I understand, it is almost impossible to do it under XP, what about Vista?

 

My wireless card is currently sharing IRQ with the Standard AHCI 1.0 Serial ATA Controller and Intel Family PCI Express Card - IRQ 17, while the audio is on IRQ 21 shared with two universal host controllers..

 

Any help is highly appreciated! emoticon.Wink.title

In the vast majority of cases this happens in models with Vista pre-installed.

I don't know of a way to change the IRQ's in the Dell laptops running XP except by switching out of ACPI mode. My thinking is that the IRQ settings are not the problem because the shared devices are ACPI compliant (and each has its own virtual IRQ according to forum member bill.newell). I also don't know if there is a way in Vista.

Re: Inspiron 1525 audio/wireless issue..

Tnx Jimco:emotion-1:

In the mean time I've stumbled upon a very interesting link, it's not mentioned in the Choppy/Skipping Audio Workarounds thread, and it seems to help, at least for people using the Windows XP.. If your audio cracks have a pattern of happening every 60sec, this might help..

 

(to check the timing of your audio cracks, use DPC Latency checker or Ping Plotter or similar freeware..)

 

Here is the link: http://www.geekstogo.com/forum/Wireless-Network-Ping-Spikes-t101910.html

 

Basically, go to Start - Run - type: services.msc and in the opening window scroll down untill you see Windows Zero Configuration (in XP) or WLAN AutoConfig (in Vista).

 

Try stopping it and watch what happens - unfortunatelly in Vista you will loose your online status by disabling this option, but in XP you will stay online - and audio crack

free!

 

In my case, I tried it in Vista - and it works!! However, it kills my wlan connection, and so far I haven't been able to found a solution to that..If I switch to XP the audio cracks loose their patern and repeat at random rates, so this solution isn't the right one for me..

Thanks for that tip. If you don't mind I will add it to Choppy/Skipping Audio Workarounds the next time I do an edit.

No problem, I would be more than happy if it were to help at least one person out there, 'cause I know exactly what it feels like to have this issue.. emoticon.Wink.title
