I have suspend and resume functionality working by using newcons and i915kms.ko as the video driver, but whenever I plug in and use my usb DAC, either by choosing it in applications supporting OSS or by setting it as the hw.snd.default_unit and then disconnect it without terminating the audio applications, I can't enter acpi s3. When trying to suspend the system I get repeated messages on the console: "Waiting for sound application to exit!" (as documented here: http://baitisj.blogspot.it/2015/05/usb-audio-disconnect-woes-in-freebsd.html) but I can't react by killing the incriminated pid since ttys are already unavailable, and I'm forced to perform an hard reset
