Public bug reported:
I've a Tohsiba x20t-C-121 (Skylake m7-6Y75 based). On initial boot,
sound on internal speakers is working. After standby it doesn work
anymore, but a analog headset does. Switching around in pavucontrol
doesn't work... Internal microphone works.
I'm using Ubuntu 16.04 64 bit on a 4.4.0-34-generic kernel.
