The speakers randomly give a pop sound (like tuck) while say when I'm browsing facebook and while scrolling I see a video which auto-plays (Even though without Audio). I also hear it randomly at other times whose pattern I have not been able to identify but sometimes before playing an audio and after stopping it.
The audio itself is fine. I can't 'disable enhancements' because I am left with only turning on or off Dolby Audio. I don't see how to update the Dolby Audio within the program itself as it just shows this:
I then tried updating the Realtek SST driver through device manager and it detected a better one however after quite some time of downloading and installing where it felt it was stuck/frozen, I was displayed a message along the lines of a better driver was found but encountered an error while installing.
Rolling back did not work so I uninstalled and restarted. Now it says that the best driver is already installed. I assume the latest one has been installed.
Realtek High Definition Audio (SST) 18.104.22.16801 4/19/2016
There's another Intel Smart Sound Technology, Display Audio and NVidia Virtual Audio Device. All up-to-date.
The audio occasionally fixes itself so I kept running the Latency test until it detected again. The popping didn't happen so it didn't reach red as frequently as when it did before but the program did say that there could be issues in playing real time audio etc.
I ran a DPC Latency and here's the report
Note: My laptop is just a month old which was a display piece at Carrefour prior to me buying.
_________________________________________________________________________________________________________ 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 0:16:44 (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.
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.
