    Skype sound 'crackling and buzzing'

    Hello all,

    I had this problem on 12.10 and fixed it using this:http://askubuntu.com/questions/15789.../201747#201747

    Now when I follow the same instructions I cannot find this line: load-module module-hal-detect

    I really need to get the sound on skype sorted (again) as I use it a lot for work. I did an upgrade from 12.10 to 13.04 and everything else is purfect, just this issue with skype I cannot resolve using the previous method

    Thank you

    Then look for load-module module-udev-detect ?

        I think you've opened the wrong file. The content that you pasted out is from
        Code:
        daemon.conf
        however you have to edit the
        Code:
        default.pa
        file.

        Enter this in the terminal
        Code:
        sudo gedit /etc/pulse/default.pa
        to edit the file straight away.

              Hello, I still have the buzzy crackling sound in skype. The fix above worked last time.

              Any suggestions? I really need skype
