Hello, i have just installed lubuntu lxle on my wife's compaq cq60 laptop mainly for her facebook and music. After installing i loaded all her music and everything worked a treat. I then updated and there is no sound at all not from any music player movie player or you tube. I checked the volume settings and they are all turned up. On the same laptop i have mint 13 installed and it works fine (i thought i maybe broke something). I then booted into the pre updated kernel of lubuntu when the sound worked and it doesn't work in there either now. any suggestions and if it involves fitting drivers could you explain what to do please thank you for your time ,Brian.
