Xubuntu 18.04 - No sound
Solution 1
I have had the same problem after each restart. I don'n know clear solution, but workaround.
$ ps -ef | grep pulse
gdm 1293 1164 0 11:12 ? 00:00:00 /usr/bin/pulseaudio --daemonize=no
root 1460 1 0 11:12 ? 00:00:00 /bin/sh /snap/pulseaudio/9/bin/pulseaudio
root 1687 1460 0 11:12 ? 00:00:00 /snap/pulseaudio/9/usr/bin/pulseaudio --exit-idle-time=-1 --disallow-exit=yes --system -F /snap/pulseaudio/9/etc/pulse/default.pa -p /snap/pulseaudio/9/usr/lib/pulse-8.0/modules -n
haripra+ 3268 2078 3 11:15 ? 00:00:08 pulseaudio --start
haripra+ 3578 3257 0 11:20 pts/0 00:00:00 grep --color=auto pulse
If I kill (e.q. $sudo -kill 1460 etc.) the processes, Pulse audio started, bu still even if the connection from pulse to the sound HW is established, Pulse not know about streams and applications.
In the Settings, test speakers works, but there is still no sound. After restart, the problem is back.
According this page Establishing connection to PulseAudio. Please wait ...
$ pulseaudio --check
$ pulseaudio -D
E: [pulseaudio] main.c: Daemon startup failed.
1) Reinstall PulseAudio and Alsa libraries according for examamle here: No Sound In Ubuntu And Linux Mint
In fact i used different way - Synaptic package manager. Install Pulse Audio Volume Control.
2) Delete in your home ~/.config/pulse
directory. This is the key step.
3) Restart system.
Don't try
To change manually anything on this Tab:
Attend to change configuration causes, that there will be again the same problem described above and you must repeat step 2) and 3).
Also to check sound in Settings -> Sound Test speakers probably doesn't work. But streans are visible (Applications Tab) and sound is back.
Solution 2
I recently upgraded to Xubuntu 18.04 LTS and didn't have any audio either.
I researched the relationship between Alsa and Pulseaudio which was very helpful. I purged and reinstalled alsa and PulseAudio as suggested above. Went to Alsamixer in a terminal and saw that the speakers were turned up full. PulseAudio Volume Control was already installed, so I played a YouTube video and in PulseAudio Volume Control I could see the audio and adjust its level. Still no luck.
Then I started going through the tabs in PulseAudio Volume Control. When I went to the tab called Output Devices, I noticed 3 little icons in the upper right-hand corner. One of them looked like a button making sound waves, and it seemed grayed out. I clicked it, and lo and behold: Sound! The Speaker output device was muted! Why it would ship with the speakers muted I can't guess, also I went through so many other places it could have been muted by some other program. Dunno.

Solution 3
Open pulse audio volume control.
Select Output devices, and Show > All Output devices.
Check the sound is not muted [x].
Solution 4
i must say i dont know if what i have is similar or different, i have linux xubuntu 18.04 LTS and a intel soundcard. Sometimes after starting or rebooting the pc, there is no sound it shows Dummy sound driver in the trays sound icon playback menu and while then the sound is nowhere not in any application or way to get heard. so i tried
pulseaudio --check
pulseaudio --kill
pulseaudio --start
this is what i did (Above) and after doing this the icon switched from grey to white and i now working and sound is back. maybe you also want to know i use my tv via the HDMI playback for sound output (same wire (hdmi) as the video signal (hdmi also))

I'm new to Linux, been using it for less than a year. Loving it so much, accept of the fact that I have no sound on my laptop.
It seems to be a known bug concerning Intel sound card and Pulseaudio. Had it on previous version - Xubuntu 16.04, and tried to use the patch, but it's a bit too complex for me. Was kind of hoping that the new Xubuntu LTS version will fix this, but nothing happens.
As I've said - there is no sound whatsoever. The sound icon on the panel is gray, and when I open it - the mute box is checked, and I cannot UN-check it. Also, when I try to open PulseAudio Volume Control (from the Multimedia menu) it says Establishing connection to Pulseaudio. Please wait... - and nothing happens.
Here are my System Info
Host: neumatta Kernel: 4.15.0-20-generic x86_64 bits: 64 Desktop: Xfce 4.12.3 Distro: Ubuntu 18.04 LTS Machine: Device: laptop System: ASUSTeK product: E200HA v: 1.0 serial: N/A Mobo: ASUSTeK model: E200HA v: 1.0 serial: N/A UEFI: American Megatrends v: E200HA.207 date: 02/01/2016 CPU: Quad core Intel Atom x5-Z8300 (-MCP-) speed/max: 480/1840 MHz Audio: Card Intel HDMI/DP LPE Audio driver: HdmiLpeAudio Sound: ALSA v: k4.15.0-20-generic
Any help is more than welcomed. But do have in mind I need step-by-step help :)
Thanks in advance!
