I'm new Ubuntu user I have install it few days ago I add my sound playing good but today I just realize that nothing is coming out of the speaker. I have tried all the settings sound settings nothing work out.
Please help!
The relevant details of my system:
sudo apt-get install pulseaudiooutput
:
Reading package lists...
Done Building dependency tree Reading state information...
Done pulseaudio is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 85 not upgraded.
Here is the info from ALSA Information Script . And I didn't mute anything.
lspci -nnk | grep -iA2 audio
:
00:14.2 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] IXP SB4x0 High Definition Audio Controller [1002:437b] (rev 01)
Subsystem: Toshiba America Info Systems Device [1179:ff10]

alsamixer
:
cannot open mixer: No such file or directory
SOLUTION:
I got my sound back and thanks to Xubut-Tur for your link I had to sudo alsa force-reload
lspci -nnk | grep -iA2 audio
also type in terminalalsamixer
and check audio settings if it's not muted by accident.
