The issue of #3 is a known issue in the pulesaudio. About the hdmi audio can't be detected, maybe it is the graphic driver's issue, do you install the nvidia-drivers after upgrading?

Problem with sound. Status in alsa-driver package in Ubuntu: New Bug description: Hi, after the last Ubuntu updates, I have lost the sound of my screen speakers (yes the monitor has got integrated a speakers), this sound is provided from the GPU via HDMI: [System Product Name, Nvidia GPU 82 HDMI/DP, Digital Out, HDMI] Sometimes when I reboot the PC, it works and detect the Nvidia GPU 82 HDMI/DP and I can hear the sound of the screen speakers. But a lot of times when I switch on the PC the selected sound card is Digital S/PDIF Family 17h and I can't hear nothing when it happens. If I try to change the sound card, I can't, it doesn't appear in the sound settings options. If I use Pulse Audio, It doesn't appear in it too. Please, fix this bug, It is very annoying to turn on the PC and not hear anything.
