A strange issue started happening, with my USB connected DAC (fiio k3). After waking from sleep/suspend the DAC is not recognized anymore, unless I replug it.

It seems like a kernel issue. Check the latest kernel and report on the alsa-devel mailing list or https://bugzilla.kernel.org (Audio component).
