Just bought a new pc and new monitor. When i plug in my earphones/headphones to my monitor the sound works, i can listen to videos and stuff but when i want to talk on skype i cant hear my friends and they cant hear me. It says theres no sound card detected. Then when i plug in myheadphones/earphones into my pc's headphone jack, i can hear sound but its extemely low. Maybe i have to adjust something in the window that pops up when i plug my headphones/earphones into my headphone jack. Then finally, when i plug in my headphones/earphones into the microphone jack on my pc, skype doesnt give me the "cant detect soundcard" message but i cant listen to videos or anything. What am i doing wrong. Do i need to buy external speakers or something. I just want my mic working and speakers at the same time. Someone please help.
