Audio turned off after wake up

[yshinkarev]

Kubuntu 18.04.02
nvidia 1050 TI (390.116)
Turn audio on by sudo tee /proc/acpi/nvhda <<<ON, set GP107GL as default output.
Suspend laptop, wakeup and OS has audio off.
If I execute again sudo tee /proc/acpi/nvhda <<<ON, back GP107GL as default output.
Can I fix it?

In the scripts directory, there's a systemd unit nvhda-resume.service for that purpose. Copy to /etc/systemd/system, run 'systemctl enable nvhda-resume' as root.
