Did that, and no problems there either, listened to about an hours worth of  AC/DC Video with not a single glitch.

After a lot of playing around and tweaking stuff, I finally gave up.

I am going to get a clean install of Win7 on my laptop and see if that fixes anything.

Out of curiosity, is your laptop an Asus laptop?

I think I fixed it? =D

4 minutes in and still no stuttering.

7 minutes into listening session and still no stuttering. I think I can say I've had success.

 

Now I gotta figure out what solved it... lol

 

So here's what I've done so far:

 

Drivers updated/rolled back:

All of the drivers were obtained from the Lenovo support website, some of them haven't been updated in years and I had newer drivers installed on some devices and older on others. The drivers were installed in this exact order with a reboot between each install

-Realtek High-Definition Audio Drivers

-Intel Chipset Drivers

-Intel Wifi Link Drivers

-Wireless Lan Drivers

-BIOS Drivers

 

On Device Manager:

-Disabled power management for usb ports (all of them)

-Disabled power management for wifi adapter

-Disabled Microsoft Virtual Wifi Miniport adapter

 

-Disabled Windows Defender and Microsoft Security Essentials

-Enabled McAfee VirusScan Enterprise

 

-DVD+R DL inside my optical drive

Why this is relevant: I read somewhere that a guy was getting DCP latency spikes caused by interference between his eSata port and Optical Drive and that he solved it by disabling either in the device manager, this was not an option for me as I use my eSata port to connect to my 2TB external HDD and I use the optical drive to listen and rip CDs. A few posts/pages later in the same thread I read that someone fixed the issue by having a CD inserted in their optical drive and that when they removed the CD, the DCP latency problems returned.

 

-Laptop is plugged in and on High Performance Power Plan, (No CPU Throttling)

 

-Modi is plugged into my eSata/USB Port

 

Et Voila! No more stuttering.

I've been listening to my iTunes library ever since I started writing this and mixing in some youtube videos to see if I hear anything out of the ordinary and there's nothing but pure pleasure and uninterrupted audio nirvana. beyersmile.png

 

And a little something for you all:

Does latencymon show it as fixed?
And if it is, please share.

Testing with LatencyMon right now.

 

 

LatencyMon shows that I'm still having issues but I can't hear them...

I am currently running iTunes to play music on my Apple TV, running uTorrent, Steam, a mute Youtube video, and Skype on the background while listening to music on soundcloud and streaming my display over to my iPad wirelessly. I don't think I can stretch my laptop connectivity much more than that... Still no stutter.

I could try running solidworks on it but I think thats overkill given that I usually don't have half of these running at the same time...

 

LatencyMon definitely doesnt like all this stuff running at the same

_________________________________________________________________________________________________________
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  0:27:24  (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):   4824.631174
Average measured interrupt to process latency (µs):   7.011752
 
Highest measured interrupt to DPC latency (µs):       2196.279666
Average measured interrupt to DPC latency (µs):       3.305071
 
 
_________________________________________________________________________________________________________
MEASURED SMI, IPI AND CPU STALLS
_________________________________________________________________________________________________________
The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.
 
Highest measured SMI or CPU stall (µs)                60.551636
 
 
_________________________________________________________________________________________________________
 REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

 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:                 chrome.exe
 
Total number of hard pagefaults                       547
Hard pagefault count of hardest hit process:          251
Highest hard pagefault resolution time (µs):          531143.939348
Total time spent in hard pagefaults (%):              0.098403

So what did you do that lead to the fix?

I'm not quite sure yet...
I wrote down everything I modified on my previous post.
I will backtrack in the morning as it's 2.30 already and I'm supposed to be at the airport at 5...

What the hell, it's only a couple of hours.

Laptop back on battery power and on balanced settings.
No stutter.
DVD drive empty.
No stutter.
Reboot.
Switched to DT770s from D2000s
No stutter.
Modi switched to other USB port.
No stutter.
External HDD plugged into eSATA.
No stutter.

Must've been one of the drivers. I've reverted everything else and I am getting no stuttering problems.

I just heard it stutter as my external HDD got woken up for a file transfer so I would assume that those power management options must be doing something right.
