I have Toshiba Satellite L-50 laptop which originally had Windows 8.1, after I upgraded it to Windows 10, all these audio problems started. I'm thinking it could be caused by the outdated drivers which TOSHIBA updated for Win 8.1 in 2013 or 2015.
I have updated drivers only manually with .inf files in device manager.
Here's how it sounds: https://clyp.it/ks3xzdrc
Whenever I have opened 20 tabs on Chrome, including 3 youtube or more tabs playing audio + I have opened some video game and MusicBee player opened, when I start playing one of these audio sources, my audio starts crackling, it's impossible to listen to anything. It goes away when I open DTS Sound panel and turn off the enhancements. And this is happening while using High Performance power plan. But I can't not use DTS, because without it the sound is very low quality, dry, no bass, nothing, just plain sound..
Specs:
- 16 GB RAM
- NVIDIA 740M
- IDT High Definition Audio
- Intel Quad core i7-4700MQ
I also did LatencyMon tests and these are the results:

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. 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 1:01:08 (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.
Highest measured interrupt to process latency (µs): 6163.758486
Average measured interrupt to process latency (µs): 4.369088
Highest measured interrupt to DPC latency (µs): 6159.909611
Average measured interrupt to DPC latency (µs): 1.666508

Highest reported total ISR routine time (%): 0.038663
Driver with highest ISR total time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation
Total time spent in ISRs (%) 0.047170

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.

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: musicbee.exe
Total number of hard pagefaults 27965
Hard pagefault count of hardest hit process: 8938
Highest hard pagefault resolution time (µs): 300129.554720
Total time spent in hard pagefaults (%): 0.224020
Number of processes hit: 36

ndis.sys = network related driver. so update all network drivers. – magicandre1981 – 2017-03-04T07:38:30.770
