I'm using an MAG B650 Tomahawk motherboard with Sennheiser HD 560S headphones and an ABLET boom microphone. The microphone is attached to the headphones, and the cable runs through a headset splitter with separate headphone and microphone plugs. The mic volume is barely audible even when I speak normally. Increasing the input level to 100% and adding 10 dB of boost makes it louder, but also introduces noticeable static and background noise. The same low volume occurs when I connect the headset directly to my laptop, so I'm unsure whether the issue is the microphone, the splitter, insufficient mic power, or the PC's microphone input. What should I check, and what are the practical solutions?

First, make sure the splitter is the correct CTIA headset type and that the microphone plug is fully seated. Also check the mic level in Windows and test both the motherboard’s rear mic jack and the front-panel jack. If the microphone is equally quiet on two different devices, the splitter, plug wiring, or boom mic itself is more likely than the motherboard. The volume wheel on the cable only controls headphone audio; it won’t increase the microphone signal.
Software such as Voicemeeter or Equalizer APO can add gain and apply noise suppression, but it won’t fix a faulty connection or weak microphone capsule. Before relying on software, confirm the microphone is selected as the input device, disable any exclusive-mode enhancements, and test it in a basic recorder. A USB adapter with a decent microphone preamp should be much quieter than the motherboard input when extra boost is needed.
