No sound output to speakers

Please follow https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Thank you for this. I have already followed that entire FAQ with no success.

To start, from step #1, (i.e., killall pulseaudio; pulseaudio -k ; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*), I receive the following response from the CLI:

"rm: cannot remove '/home/zachary/.pulse*': No such file or directory"

Output from step #3 (wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh):

I have provided the requested information almost 2 weeks ago. I would like to know whether anyone can help me further before the question is automatically closed by the system?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Is anyone actually monitoring this thread? I still have this problem, it has been over a month, and I have followed the requests for information as stated and this thread keeps going inactive due to lack of feedback.

It seems that nobody has an idea how to proceed.
The alsa-info script shows that drivers are loaded, so it is not clear why there wouldn't be sound on your speakers.

The only thing I can imagine is that here are some additional settings needed, e.g. like those in comment #2 of https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/694108

Thank you for your insight.

I have tried the addition in your referenced comment, restarted my computer, but with no success.

The audio works perfectly well with bluetooth speakers, bluetooth headphones, and headphones plugged into the audio jack on the computer. The bar under "Output Device" in "Settings">>"Sound" does respond as though the computer is attempting to deliver audio to the speaker, but there is no sound, no matter what volume the computer is set to (or muting/unmuting audio, adjusting various levels, etc).

Par for the course at this point (I understand that there isn't much knowledge or experience with running Ubuntu on the new Intel evo platforms), but I'm re-opening this question since it still has not been able to resolve (speakers still aren't functioning when booted into Ubuntu, but works fine when audio is run through headphones on Ubuntu, or when computer is booted into Windows10).

This is still an issue.

I have given up on this. Since there have been no answers and no insights in months, I am uninstalling Ubuntu form my machine.
