Fresh install, no sound...

[gabsnow]

Hey guys!
I just installed Linux Mint 18.3 Cinnamon 64-bit and i have no sound at all.
I checked the sounds settings to be sure nothing was muted and i can't even change my output device. There's also nothing in the output profile that works.
I am connected with a HDMI cable on a smart TV, if this helps.
I hope someone can help me fix this...i'm new to Linux so maybe there's just something i didn't think of.

Here are my system and audio information:

Open a terminal an run the following to reinstall some audio-related packages, when prompted type in your password.:

Code: Select all

sudo apt-get install --reinstall alsa-base pulseaudio pavucontrol

Install alsamixer:

Code: Select all

sudo apt-get install alsamixer

Run alsamixer in a terminal by typing "alsamixer" (without quotation marks), enter:

Press F6 and in the menu choose your audio card.
When it's done, check if you get the sound.

go to .config/pulse/ folder in the home directory, delete everything in that folder and reboot

Hi and sorry for my bad english
I have the same, no sound with Linux Mint 17.3 (but sound with Opensuse 42.1)
I try/change many thing, pulse, pasvu, alsa (and Lorraine )

until, because "Meltdown Spectre", I change the kernel

and just my experience

Fresh intall 18.3 cinnamon yesterday.
Hdmi display port won't work properly. Sound seem's to be high pitched with no reason at all.
Using spdif out working very well.
My mint iso is 2 month aged so possibly pulse audio get major updates since.
triying ~/ sudo apt-get upgrade pulseaudio

Problem solved

No need to change Alsa and Lorraine at all
