I am totally new to Ubuntu so please forgive my ignorance :) I was trying to read the previous posted questions but none seem to be the same as what I have right now. (Please point me in the right direction if I missed it)
I installed a dual boot of Ubuntu and Windows7 on my laptop and now there is no sound output when I am in Ubuntu...
Well, mostly no sound because after tinkering with the alsa mixer I managed to make the clicking sound come out when I click the mute/unmute option in the sound settings. Other than that clicking sound there is totally no sound. Please help.
I just wanted to add the details from the terminal about the output, I have no idea if this information would be helpful.
lspci -nnk | grep -ia2 audio
