Dell Latitude E7440 audio problem

Hi,

 

My Dell Latitude E7440 laptop has an audio problem so far, I was hoping that this bug will be resolved on High Sierra, but unfortunately it still has ... :(

Unfortunately, sometimes the sound disappears from time to time. You do not see the system any problem, but there is simply no sound on the loudspeaker or earphone output.

The problem I do not know is what it is like to solve it, once it is self-restored, then it will break out again after a while ...

Does anyone have an idea why this can be?

Thank you for your help!

Then unfortunately I have some other problem ... :(

The contents of the LE folder are copied to the specified location.

I run the scripts.

Meanwhile, I noticed the sound on the headphone output.

The speaker is also good, running Windows 10 works perfectly ...

Do you have any idea what to reinstall?

I usually run the following script:

sudo chmod -Rf 755 /L*/E*

sudo chown -Rf 0:0 /L*/E*

sudo touch -f /L*/E*

sudo chmod -Rf 755 /S*/L*/E*

sudo chown -Rf 0:0 /S*/L*/E*

sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /

What are you thinking about running the script exactly?
