I just installed LUbuntu 16.04 onto my laptop, which is a HP Pavilion G6 series, AMD Processor, and it does have an HDMI port. I can't seem to get audio or any sound at all to come out of my laptop. I made sure I updated what I could find and even searched forums for different audio software but none have seemed to work. Some of thoses being Alsamixer/gui,pulse audio, and another one which I can't quite remember. Is there any way that I can get my audio to work?
(UPDATE)
I was able to get it to work,it was the HDMI port and I installed the pulse audio controller. Thank you all for the help!!!

Before anything, make sure your sound is not muted.
ALSA and PulseAudio don't get together well. They are conflicting each other most of the times. Unless ALSA is specifically required by an app or hardware I recommend using only Pulse (it's newer and better).
First, remove alsa completely by opening a Terminal window and typing:
Secondly install Pulse:
pavucontrol is the graphical interface for Pulse, but it will install Pulse completely (as its dependencies).
And finally, type:
A Pulse window should come up with many tabs and options. Make sure the inputs and outputs matches your connection (hdmi, usb, headphones, etc), and make sure Pulse is using the correct audio card (on-board, dedicated, external usb/hdmi device, etc). E.g. When connecting laptop to large screens via hdmi, Pulse might detect the hdmi audio card as external output device with specific brand (not necessary the same as vendor brand). If so, you must choose that external card as output to make audio work.
Be aware that Ubuntu doesn't support hdmi hot-plugging! After disconnecting hdmi device, Pulse (or ALSA) will not fall-back to previous settings. You have to change the settings (again) and then restart the Pulse audio service by log out + log in in order to make things work again.
