I have a 7" screen that connects via HDMI to raspberry.
But when I connect the HDMI cable to the raspberry, the DAC mutes…

Can any one help ?

Yes, this is a simple configuration file change.
Go to the System configuration tab and scroll to Local Services>SSH Term server and set to On. Then "Open" below it.
You are asked for your a login ..it is pi (and enter.)
You are asked for a password ... it is moodeaudio (and enter.)

This will bring you to a screen like this..

__ _ ___ / __ \___/ /__
/ ' \/ _ \/ /_/ / _ / -_)

Now type..
sudo nano /boot/config.txt (and enter)
you will see something like this...

disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt
enable_uart=1

use your arrow buttons to reach... hdmi_drive=2
and change 2 to 1
then use ctrl + O (to overwrite)
and y (to accept)
and ctrl + X (to exit)

Then reboot moOde and you should have video to the screen and audio to the dac. :-)

If this does not work post details, any error messages, and the brand and model of your DAC.

Thanks for the replay
One thing I tryed before was "hdmi_drive" from 2 to 1, no result
I remained with the "dtparam=audio=off" because I believe that it turns off the onboard audio
I tried with ON and I has no sound with or without HDMI plugged
I added also "enable_uart=1"

The problem persists, if I plug the HDMI cable, DAC mutes, if I unplug it, DAC resumes

Now my config is:

Code:
disable_splash=1

disable_overscan=1

hdmi_drive=1

hdmi_blanking=1

dtparam=i2c_arm=on

dtparam=i2s=on

dtparam=audio=off

enable_uart=1

hdmi_force_hotplug=1

hdmi_cvt 1024 600 60 3 0 0 0

hdmi_mode=87

hdmi_group=2

dtoverlay=hifiberry-dacplus

#dtoverlay=pi3-disable-wifi

#dtoverlay=pi3-disable-bt

My DAC is a PiFi DAC+ v2.0, that I beleave is a hifiberry-dacplus clone

First revert /boot/config.txt to stock or there might be issues.

Menu, Configure, System
Local UI display ON

There is no guarantee that the UI layout will work on your particular screen depending on its aspect ratio, resolution and reported Browser viewport size.

I have no problem with image, just audio, and the config.txt is stock, I only added the changes to try to resolve this issue.
I still want audio from DAC besides the fact I have an HDMI cable connected to the screen.

Found the problem, it's hardware

I do not need to plug the hdmi cable for dac to get mute. If I just touch (not connect) the hdmi metal to the metal of the hdmi port on the monitor, the audio just mutes
