Radio stutter but only with headset

[RiShooty]

Hello. I have noticed that the radio stutter issue does not occur on my normal speakers, but does occur when I use my headset. I could never find the cause of this as there seem to be no differences in settings between the two. I've noticed that using madfilter does in fact fix the problem but unfortunately it increases the instability. My game performs much better without madfilter so it doesn't seem to be worth it. The only difference I have found between my speakers and my headset is that when i right click my headset speakers it comes up with "about software midi synthesizer..." which then says: Microsoft GS Software Wavetable synthesizer featuring roland sound canvas digital. You think this codec could have anything to do with it? and yes my drivers are up to date and I have tried doubling iAudioCacheSize without any luck.
