I have been using Ubuntu 15.04 for a while on a Pavillion x360. Everything worked perfect! After the last time I ran:
sudo apt-get update sudo apt-get upgrade
I started getting error messages. That automatically requested me to submit them, which I did.
I removed alsa-base and pulseaudio. Re-installed them both, but also installed pavucontrol. When I entered System Settings and entered Sound and Display. The panels are transparent. The sound devices both on-board pci
00:1b.0 Audio device: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller (rev 0c)
and HDMI sound no longer were present.
Both devices still work, but the panels on system-settings are not working right.
Is there a way to have ubuntu restore to install defaults?
Thanks in advance for any reply.
