Hi Gysselylth - Welcome to LQ.

Often, this issue can be solved by unmuting the audio channel using alsamixer. Use this command:

Code:

alsamixer

... and then check if the main and / or other slider is muted ... you'll see the letters "MM" instead of a volume level at the bottom of the slider. Press the letter "m" on your keyboard to unmute once you are on the slider.

If it's not that, we'll need some more info to help you troubleshoot. Check the sticky at the top of the forum for guidelines on asking questions in an optimal manner.

Talk to you soon !

hi rick thanks for replying i did what you told me but it only showed me this and all are number 00 but can't chage them

Hey Gysselylth ..

OK - so it's obviously something else .. I'm assuming you're using Ubuntu, from your icon. I'm not an Ubuntu user, so am unsure how it sets up sound by default. Do you know if you are using pulseaudio, for instance ?

Getting back to the need for additional info, could you provide :

- make and model of computer
- make and model of sound adapter
- version of our operating system (confirm whether Ubuntu or other version of linux) and Desktop Environment
- are there other operating systems installed on the computer (dual or multi boot set up ...) ?
- has the sound ever worked on this computer ? If yes, describe the conditions, please.

If you're not sure how to answer any or all of these questions, let us know and we can help you with that.

Cheers !

If you are using Ubuntu (or almost any other distro, you likely have Pulse Audio installed as a layer on top of ALSA.

Install pavucontrol, the Pulse Audio mixer; it has more granular controls than the default volume control. It should be in the repos.

Another test might be to boot to a Live CD of something not Debian-based (Mageia, OpenSUSE maybe) and test the audio.

Further to frankbell's advice regarding 'pavucontrol' ...if that doesn't resolve your issue, then some diagnostic info would be useful.

https://wiki.ubuntu.com/Audio/AlsaInfo

Quote:

Enter these two commands in the terminal:

Code:

cd ~/

Code:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

You will be prompted to upload the information or save it locally. The easiest way to share the information is to automatically upload it to the alsa-project server and copy/paste the address you're given. You can also choose to save the information locally, and alsa-info will output a text file in /tmp . You can then upload that file to whoever wants it. (Remember: files in the /tmp directory will be removed on every reboot.)

hi yes when i change the chip to HDA intel pch but i cant save it when i exit it goes back to HDA intel HDMI

Try pavucontrol before messing with anything else. It's no use doing anything else if the problem is just with the setting in pulse-audio. Debian based systems like Ubuntu often have audio problems, and pavucontrol often solves them.

I booted my computer with my USB flash memory with linuxmint-18.1-cinnamon-64bit.iso on it, so I ran a live USB session. I opened firefox and played a song on youtube. The sound worked perfectly! So I can rule out any hardware error.I'm sure it happened after these updates

Normally, I'd expect to see PulseAudio running as part of your desktop session. Which desktop environment are you using here?
