Re: 1/8" headset mic + 1/8" to 1/4" adapter = No sound on Scarlett 2x4
I suspect the adapter. Many headsets or headset/mic combos made for cell phones are TRRS. I don't know which connections are for the mic and which ones are for the headset, but the correct adapter needs to be used. Headphone jacks, on most, are stereo so you need a TRS plug.
