藍牙耳機個mic用線連唔知點解錄唔到音

我買咗個藍牙耳機 用4-pin 3.5mm 線連落部pc(win11)
部pc detect到個input 但係錄唔到任何聲音 不，
耳機聽到聲output
然後我用airpod試部pc有driver 問題
結果佢運作得好正常(input output都有聲)
咁我到呢到就以為係條線嘅問題（耳機藍牙mode都正常)
咁我用個耳機加條線連去部MacBook結果佢又work

已經上網睇咗幾十個post
解決方法不外乎都係:
Privacy permission settings
Driver update/reinstall current driver
Physical mute/software mic volume/muted
Troubleshooting

真係好心累搞咗個禮拜都搞唔掂
如果部耳機係就咁唔work咁我都可以心安理得咁去買過個
但佢插去MacBook又冇問題 部pc連其他帶mic headphone又冇問題令我唔想放棄

個input panel係mic加 headphone

你插機箱前面？
耳機咩model

Marshall major 4
佢本身比條線係3-pin 所以我自己買咗個4-pin線
連去macbook都冇問題但pc就完全錄唔到音

似乎哩款耳機插線係用唔到mic

No inline mic on the 3.5mm audio cable

但你又話插去MacBook用到mic，咁我就唔知點解

佢講果係原裝嘅3pin 線 3-pin係冇mic connection 得左右同地線

但我見佢個解決方法係要另外接mic，而唔係換條線用
而且如果有但原裝線唔畀埋，會唔會有啲奇怪

咁我諗買個外接mic 算

唔該曬你咁幫小妹
