PLTGC.sys dpc latency causing audio pops/clicks?

hello, i've been having some annoying trouble with my headphones (plantronics gamecom 780) making pop/click noises when audio starts or stops sometimes, sudden audio level changes, or just randomly in the middle of it. i've tried so many things at this point such as updating bios, all my drivers, disabling all other audio programs, toying with playback settings, power management settings in control panel, different driver versions and nothing has worked so far. i'm hoping someone will be able to help me as this is extremely annoying listen to music with intermittent popping/clicking noises and some voice communication in games. if any more information is needed i'll gladly post more. thanks for reading.

here is a screenshot of my latencymon screen when running it

and here is the latencymon report

____________________________________________________________________________________________________ _____
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 0:04:36 (h:mm:ss) on all processors.

SYSTEM INFORMATION
____________________________________________________________________________________________________ _____
Computer name: JORDAN-PC
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)
Hardware: ASRock, 970 Pro3 R2.0
CPU: AuthenticAMD AMD FX(tm)-6300 Six-Core Processor
Logical processors: 6
Processor groups: 1
RAM: 8148 MB total


____________________________________________________________________________________________________ _____
CPU SPEED
____________________________________________________________________________________________________ _____
Reported CPU speed: 3492 MHz
Measured CPU speed: 1 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.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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 (Ás): 11890.457903
Average measured interrupt to process latency (Ás): 14.249797

Highest measured interrupt to DPC latency (Ás): 3741.82630
Average measured interrupt to DPC latency (Ás): 9.594367


____________________________________________________________________________________________________ _____
REPORTED ISRs
____________________________________________________________________________________________________ _____
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (Ás): 176.644330
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.083988
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.168633

ISR count (execution time <250 Ás): 390441
ISR count (execution time 250-500 Ás): 0
ISR count (execution time 500-999 Ás): 0
ISR count (execution time 1000-1999 Ás): 0
ISR count (execution time 2000-3999 Ás): 0
ISR count (execution time >=4000 Ás): 0


____________________________________________________________________________________________________ _____
REPORTED DPCs
____________________________________________________________________________________________________ _____
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (Ás): 3756.711340
Driver with highest DPC routine execution time: PLTGC.sys - C-Media Audio WDM Driver, C-Media Electronics Inc

Highest reported total DPC routine time (%): 0.868098
Driver with highest DPC total execution time: PLTGC.sys - C-Media Audio WDM Driver, C-Media Electronics Inc

Total time spent in DPCs (%) 1.284633

DPC count (execution time <250 Ás): 2052380

DPC count (execution time 2000-3999 Ás): 1
DPC count (execution time >=4000 Ás): 0


____________________________________________________________________________________________________ _____
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.

Process with highest pagefault count: svchost.exe

Total number of hard pagefaults 2541
Hard pagefault count of hardest hit process: 1571
Highest hard pagefault resolution time (Ás): 505679.629152
Total time spent in hard pagefaults (%): 1.565954
Number of processes hit: 15
