Hallo,
ich habe mir erst letzte Woche einen neuen Laptop gekauft.. Schon nach kurzer Zeit ist mir aufgefallen, dass der Ton immer wieder mal kratzt.. Ich kenne mich nicht so besonders gut aus, aber hab ein bisschen gegoogelt und bin auf zwei Programme gestoßen: DCP Latency Checker und LatencyMon. Soweit ich das Problem herauslesen kann hat es etwas mit dem ACPI.sys Treiber zu tun...
Da ich davon nicht viel verstehe, frage ich mich nun, ob das Problem bei meinem Laptop eine Ausnahme ist, oder ob das wohl bei jedem Modell der Reihe auftreten würde? Also wenn ich den Laptop umtauschen würde, würde das Problem bei gleicher Nutzung vermutlich wieder auftreten oder eher nicht?
Hier das Ergebnis von LatencyMon, falls das irgendwie weiterhilft:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:51:57 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
