So I really like Breakaway Broadcast.. however I was missing that clunk/impact feeling that I was trying to emulate, anyway last night I came across the DSP's that Leif made and it's sealed the deal (only took me a couple of years to realise those plugins were there).
So I downloaded the demo again to trial it out on my new server. I setup numerous net stations as a kid and now that I have been working in the industry with a better vat of experience, I felt ready to make a much more superior station. However after around 12 hours of running it I hit the crackling, pops and huge dropouts (up to 10 seconds sometimes).
I understand there's already a thread about how some people have managed to deal with them, however having tried them all with no prevail I'm slumped again. All I have open is RadioDJ, Oddcast and Breakaway – I have been through driver settings, making sure my power management is at the highest possible and I'm still getting a bad sound. Worryingly virtual audio cables gives off a much better performance in-comparison to the pipelines included.. so much so that the included pipelines make the music inaudible.
I took it up on myself to investigate this much deeper and ran LatencyMon – here are the results (the visual version look horrifying).

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 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 0:23:45 (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): 2346.445742

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.

_________________________________________________________________________________________________________The server is hosted by Hetzner in Germany, so I have no real access to it unfortunately. I have ran Stereo Tool with the same setup on another machine (exact same spec) and it was perfect, no dropouts or pops/crackles for over 6 months – which is why it's really hitting me hard because I've suddenly fallen even more so in love with this product!
Any more possible advice? Could the ASIO version be of any help or is this likely to delay the dropouts (etc) for a little bit?
Thank you.
Yeah that seems to have smoothed it out a little – it's been going 12 hours without any issues so far, however it was stuttering with VAC before during the test; switching the stream buffers to auto seems to have done the trick for now.. everywhere seems nice and slick again http://media-ice.musicrad.io/oxygen
