Crackling distorted sound... and how does one fix things in Linux?

Post by gino_serpa » Sun Apr 16, 2017 8:09 pm

Hi All,
I just installed Linux Mint 17.3 64-bit Rosa. Everything went ok but the sound is distorted and crackling. I googled the issue and found so many suggestions (add tsched=0 to this file, mess with the alsamixer, etc.) and none worked. I know there is a fix since when I used Ubuntu there was no issue in the same computer. Below I posted my "inxi -Fxz" output and would appreciate any help but I also have a more general question (this is why I posted in the newbie question instead of in the sound or drivers section). Is this the way to fix things in general? I mean googling you find so many fixes to problems in linux and I am always think what if I do this or that change and the whole thing crashes or worse if my changes produce oter changes that I am not aware of? Specifically for problems with sound like mine, is there a methodical check list that can help me get to the root of the problem and fix it? Any help would be greatly appreciated .
And now as promised, the output of my inxi -Fxy. Thanks in advance
Gino

Have you tried Linux Mint 18? In anycase type this in terminal this can take time.

Code: Select all

sudo alsaconf
If this does not fix the issue this will force alsa to reset type in terminal if the above command fails to help

Code: Select all

sudo alsa force-reload

Hi Dave,
I will try Mint 18 if you think that would help

I executed the commands you suggested. aslsaconf gave a command not found while the second command executed but did not fix the problem.
Thanks for your help though

gino@gino-main ~> sudo alsaconf
sudo: alsaconf: command not found
gino@gino-main ~> sudo alsa force-reload

"a methodical check list" I doubt it, although an experienced technician can fake a similar result. Here it's all peer-reviewed opinion.
o Avoid 'sudo' commands and your system will survive unharmed.
o For some things, you have to use root-privileges with sudo. You (almost certainly) will damage your Mint at some point, that's why we whinge endlessly about data-backups and os-clones. It's going to happen, so be prepared.
o Confirm the hardware can actually perform [tick] It works with Ubuntu (which one?)
o Confirm your installation is intact. That's boring but easy...debsums | grep -v "OK"
I get the following list, nothing bad. 'FAILED' just means 'different to the repository version'.

o Try a different sound system. Mint has pulseaudio and alsa. Say which one you are using. Say what happens when you change. The Audacious player lets you switch output system and bit-depth.
o Do quiet sounds have the same problem? Floating-point sound processors can overdrive to more-than-100%. Is it clipping, or something more complicated?
While you're waiting, read the free novel we sent you. It's a Spanish story about a guy named "manual".

Try this in terminal. To be fair you should install 18.1 your system is good for it. Just try live booting before you install it to make sure everything including sound works.

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload

Problem solved!
Installed Mint 18 and the sound now works. Bach is playing as I type and it sounds like Bach
Thanks to all that contributed, this was a very educational experience
Peace!

After a sudo apt-get update && sudo apt-get upgrade, my audio was distored like an fm radio that was out of range
Thanks to this thread, the following terminal commands fixed it right away. Thanks for the help.

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload
