Netbook - sound popping, cracking, lagging
I am struggling with odd sound cracking, popping, sometimes it slows down a little bit.
It's netbook Acer Aspire One D720 with Realtek soundcard, 2 GB RAM and Win 7 32bit Home Premium installed.
At first I though that problems start when there is a high CPU usage
But then problem started to occur even when CPU usage was pretty low.
I discovered term DPC latency, so I downloaded utilities to test my netbook.
Running DPC latency checker it was clear that my DPC latency is pretty high, sometimes about 30000 at max.
Also, LatencyMon showed me, that ndis.sys has the highest execution time.
So I tried to turn off my LAN adapter. Something has changed. Sound lags and cracking have been reduced, but sound wasn't 100% clear. So I turned on LAN, and disabled Wifi adapter. Sound was now a lot worse, and the highest execution times belonged to usbport.sys and sometimes ataport.sys
When I installed IDE drivers it was even worse. Also, I installed latest Wifi, lan, audio and graphic drivers. I tried to disable swap, modify various audio settings.
Recently, I was listening to music, and it started to crack in some periodic intervals, it lasted for a while, and then it returned back to normal. I captured it in DPC latency checker
I don't know what to try next, problems still persist, and it is driving me crazy. What else you suggest me to try, any ideas?
