I started having audio issues yesterday when I would watch twitch.tv or youtube and searched around trying to find answers for the problem. I updates all of my drivers and changed power management to see if it would fix the problem, but it didn't I saw a few answers to run LatencyMon to see what the problem was and this is the full report I have after running it. I have a Lenovo Y410P

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. 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 0:09:29 (h:mm:ss) on all processors.

_________________________________________________________________________________________________________
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: 20216, LENOVO, VIQY0Y1
CPU: GenuineIntel Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Logical processors: 8

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2394.0 MHz
Measured CPU speed: 3324.0 MHz (approx.)
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

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.
Highest measured interrupt to process latency (µs): 11346.481658
Average measured interrupt to process latency (µs): 7.217776
Highest measured interrupt to DPC latency (µs): 11331.941466
Average measured interrupt to DPC latency (µs): 1.488981

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.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
