Dell precision m4600 audio problems

Hello. Does it also do it when you play a dvd in your optical drive?

even reinstalled window 8.1

Was it a clean install or a system recovery? Because if the audio worked all right when the laptop was brand new but continues to have the problem immediately after a system recovery, then the problem was caused by hardware failure of some sort.

======================================================================

I just checked the M4600 support page and see that Dell does not support 8.1 on it. Did this problem begin when you switched to 8.1 from the original operating system?

it happens in the beginning when i install win 7, so i clean install to win 8.1 to see if that error remain, and it remains :(

I asked some forum, they told me that error was DPC latency, i ran LatencyMon to check, i found out it because the internet connection, when i plugged out the network cable, the error seems to disappear, so i wonder if that error is about the network cable or it's my laptop 's network joint, or because win 8.1 isn't supported in m4600.

thanks for your reply anyway :)

It could be the Ethernet controller driver. I don't see one for 8.1, but there is probably a native driver for it in Windows. You could try opening Device Manager (type devmgmt.msc into your search box), expand Network Adapters, right click on Intel 825xx and click Update driver.

That probably won't help though.

or because win 8.1

You had the same problem with 7 so 8.1 is not the cause of it.

If this problem did not exist when the laptop was brand new then you can fix it by performing a system recovery -- that means restoring back to the original factory configuration by using your recovery media.

thank you for your advise, i will try that, hope it may help :emotion-1:
