Installed Lubuntu 16.04 version no audio now
Solution 1
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:
sudo apt-get remove --purge alsa
Secondly install Pulse:
sudo apt-get install pavucontrol
pavucontrol is the graphical interface for Pulse, but it will install Pulse completely (as its dependencies).
And finally, type:
gksu pavucontrol
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.
Solution 2
I tried everything that was ever recommended online, I was only able to fix my PC sound issue by running the following commands:
killall pulseaudio
rm -r ~/.config/pulse/*
rm -r ~/.pulse*
Some directories may not exist, that is OK.
then:
pulseaudio -k
then reboot
I found this solution here, there are also some other recommended solutions if this doesn't work.
Solution 3
I did all the above to no avail.
What did work was simply unplugging my desktop speakers from headphone jack and plugging them into the Line Out jack.
Solution 4
This one worked for me...
- Restart the computer
- Enter BIOS
- Go to options for front panel jacks
- Select AC97 instead of HD
- Save, boot normally
Use front panel jacks
Solution 5
'Pavucontrol' didnot help me.
Tried a lot of methods after a lot of search I tried using alsamixer.
Alsamixer helped me.
sudo apt-get alsamixer
Please open a terminal and enter 'alsamixer' and make sure the channels are not muted 'MM' or on zero level.

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!!!

Organic Marble almost 8 yearsI've some issues with audio on Lubuntu. Installing pulse audio volume control
pavucontrol
helped, and at least gives some visibility into what the problems might be - you can see the status of inputs, outputs, etc. -
Yevgen almost 8 yearsUbuntu 16.04 has some bugs with HDMI port, update of kernel till 4.4.8 solves them. Probably it might help with LUbuntu too.

ʇsәɹoɈ about 7 years-1 for claiming that PulseAudio is better than ALSA. It does certain things that ALSA does not do. While that might make some things easier (e.g. networked audio), it makes others worse (e.g. audio latency). Which one is "better" depends entirely on the individual's needs.

MHT about 7 yearsSimilar thing here :) I had no speaker sound on my laptop (also no speaker option in my sound output dropdown, only HDMI). Plugging and unplugging headphones re-enabled the speaker sound. Magic!

Keith almost 7 yearsas your post currently stands it doesn't really help the OP much. Simply dumping a bunch of commands in a one-liner without explanation of what the commands do is not up to the standards of this site.
