Qosmio X775 "popping" and "cracking" sound came out from the speakers
Posted: 09-Apr-2012 13:56

Hi,

so my problems started a few days ago when some "popping" and "cracking" came out from the speakers.
It's not all the time, but like in between 3-4 seconds i can hear it. I also connected the laptop to a speaker system and the problem remained, which means that it is not from the speakers, but from the signal.

I tried to reinstall the drivers but it seems that it's still not fixed.
Also the Waves MaxxAudio 3 disappeared when i reinstalled the drivers and now can't get it back?

Has anyone an idea of what might be causing this and how to install again the Waves Maxxaudio?

Thank.

Hi

Not quite sure what could cause this sound issue but it could be possible that this crackling sound appears due to some latency problems… in most cases this appears because the CPU is stressed by some processes running in the background.

I would recommend checking this using an tool called “DPC latency checker”.
Check if anything else is causing small DPC increases

Mostly such issues might be caused by drivers like Lan or Wlan… updates might help to solve this…

even better of a program for latency issues is LatencyMon, just because not only does it analyse the latency but also the processes or dll's that cause spikes, which makes it so much easier to investigate

helped me with WLAN causing DLC spikes apart from the ACPI battery monitoring driver

I agree… LatencyMon is nice tool… I used this in the past too… helped me to discover the background process which caused some problems while audio streaming.
