ok i have had this problem with my headphone jack as well i used this thread to fix itCDS wrote:I installed LMDE in 2 computers. One is acer aspire netbook. It works the sound using tutorial by blowtorch in this forum. Another is Acer Aspire 4710 notebook. It works the sound with the built-in speaker but it doesn't work with headphone. I tried Linuxmint 10; ubuntu 10.10. All are the same result. Speaker works but headphone doesn't. I tried solution for Ubuntu 9.10 but it doesn't work on Ubuntu version 10.10. Is this problem related to hardware related issue?
Desperately needed help!
