Hi, I'm using FreeBSD 10.2-RELEASE-p5 amd64 on a thinkpad t430.
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
Hi,
There is a bug in pulseaudio or some mixer application, that it doesn't
close the /dev/mixer or /dev/dsp, when receiving a read/write error from
the USB audio device.
Try killing pulseaudio.
