A:
First plug in your cables, then open phone-software! Your software should ask you which audio devise to use.
OR
1. Every time check if the cables are plugged in correctly. For computer, they are color coded. The RED one is the mic.
2. Go to your skype or other software and open the audio (and video) options. Select the mic and I hope your software offers MIC sensitivity ... adjust these.
3. there is always the possibility, that on the other-side is something wrong. My father forgets so switch on his speakers.
