Intel NUC - No Sound when turning on from resume

**blueribb** · June 2, 2023 at 3:12 PM

I replaced a 2013 Intel NUC with a newer model from 2018. I now have everything working perfectly except for NO AUDIO when turning on the NUC from resume. My old NUCs suffered from this same issue and mglae (developer) helped me to install a script which toggled the video resolution causing the audio to return. This always worked with my older NUCs. I SSHed into my newer NUC this morning and copy/pasted the script into the new NUC. I wasn't sure how to save and exit properly, so I just typed EXIT and Putty closed.

My newer NUC still has no audio when turning on from suspend, unless I toggle the video resolution. Was I supposed to SAVE the Putty Session's changes?

Here's a link to my old thread. The fix starts at post # 32 No Sound when turning on from resume - Intel NUC

Old NUC: DC53427HYE (2013)

Newer NUC: NUC8i5BEK (2018)

So you created the /storage/.config/sleep.d directory, and have the 20-custom-sleep.sh script as content, right?

**blueribb** · June 2, 2023 at 4:28 PM

Yes - I have the /storage/.config/sleep.d directory

The 20-custom-sleep.sh script was probably on my old NUC, not the newer one.

I know there are quite a few different fixes (patches) for this problem but has there ever been a permanent fix?

Instructions:

First go to Settings -> System -> Display -> Resolution, and note down your preferred GUI resolution. You will need it later.

On my Rpi (LE 11.0.1), the directory /storage/.config/sleep.conf.d was pre-installed. So I think that's the right one.

Please check whether you have it:

Code

cd /storage/.config
ls

If you don't have it, create it:

Code

mkdir sleep.conf.d

Then delete /storage/.config/sleep.d:

Code

rmdir sleep.d

Then go into the directory, and look what's inside:

Code

cd sleep.conf.d
ls

I have a README and a sleep.conf.sample file inside. For your purpose, you have to add two more files:

99-toggle_rate.power
20-custom-sleep.sh

To create 99-toggle_rate.power, copy the following code into your SSH terminal, and hit Enter to execute it. Eventually edit the resolutions first, depending on your preferred GUI resolution (see above). To do so, copy the script into an editor of your local OS, and edit both lines. Then copy the result into your SSH terminal, and hit Enter. In case you're trapped in input mode after this (> sign before cursor), type EOF, and hit Enter.

Code

cat >/storage/.config/sleep.conf.d/99-toggle_rate.power <<'EOF'
#!/bin/sh
case "$1" in
   post)
     xrandr -display :0 --output HDMI1 --mode 1920x1080 --rate 59.94
     xrandr -display :0 --output HDMI1 --mode 1920x1080 --rate 60
     ;;
esac
EOF

After that you should see the new file:

Code

ls

Result:

Quote

99-toggle_rate.power README sleep.conf.sample

To create 20-custom-sleep.sh, copy the following code into your SSH terminal, and hit Enter to execute it:

Code

cat >/storage/.config/sleep.conf.d/20-custom-sleep.sh <<'EOF'
#!/bin/sh

. /etc/profile

for script in $HOME/.config/sleep.conf.d/*.power; do
  if [ -f $script ]; then
    progress "running custom sleep script $script ($@)..."
    sh $script $@
  fi
done

exit 0
EOF

After that you should see the new file:

Code

ls

Result:

Quote

20-custom-sleep.sh README
99-toggle_rate.power sleep.conf.sample

Reboot, and hope that it works.

1. Resolution 1920 X 1080p

2. sleep.conf.d is already there

3. remdir sleep.d : Directory not empty

4. cd sleep.conf.d : I also have Readme sleep.conf.sample

I tried to copy the script into the SSH terminal but couldn't figure out how. I right-clicked and it seemed to copy it but when I typed ls, it wasn't there. What did I do wrong? Here's a screen shot of the results so far:

Use rm -rf sleep.d to delete the directory and its content.

The first line is obviously wrong, because we want to use sleep.conf.d, and not sleep.d as directory. Please copy & paste correctly.

**blueribb** · June 2, 2023 at 7:49 PM

I think I deleted sleep.d and sleep.conf.d by mistake. I found 99-toggle_rate.power in config.sleep.d

Oh boy - Now I'm really confused

You missed the point before config:

Quote

cd /storage/config/sleep.d

Please stay focused.

If needed, create a new directory by mkdir /storage/.config/sleep.conf.d.

I managed to get everything back in place and now both scripts are present in sleep.conf.d

Bad news is I still have no sound when powering back on from resume. I can toggle video refresh rate from 60 to 59.94, respond NO to the popup and the sound returns.

Back to square one.

I tried running this part of the script manually but got these errors:

Please check the content of the new files by nano <FILENAME>, or by cat <FILENAME>.

case "$1" in

Eventually 20-custom-sleep.sh is not needed, so also try without it:

Code

I tried different combinations to get a result but failed.
