Sound problem after suspend

After awake from suspend, I get sound drop outs.
It is not a Ardour problem, but I wonder if someone else has encountered this problem?

I am using Debian 10, but it also happened with Arch Linux no matter whether I use the internal sound card or an external sound card.

Do you use rtirq to prioritize soundcard IRQs? If so that may explain this.

The settings are lost after a suspend/resume cycle. check with:

/etc/init.d/rtirq status

You can either configure systemd or pm-utils to re-init rtirq after resume, or replace rtirq with a udev variant:
