I've upgraded from 14.10 to 15.04 and then directly to 15.10.
I have a TV connected to the computer via HDMI cable. The sound was working ok after the upgrade but after using the TV and coming back to the computer, I do not have the sound anymore.
Tried restarting the computer but no sound. When getting the logging screen, I do hear the sound though.
Looking into the settings->sound I only have the digital option and no analog option in the drop down menu.
Things I've tried:
sudo alsa force-reload
Killed the pulseaudio process and it restarted again automatically. Still no sound.
Reinstalled Alsa and Pulseaudio
$ sudo apt-get remove --purge alsa-base pulseaudio
$ sudo apt-get install alsa-base pulseaudio
$ sudo alsa force-reload
Restarted but no success. I also lost the volume icon in the top bar and the settings-sound looks a bit different now.
The device option did change though and now shows
HDMI / DisplayPort - built-in Audio
instead of just built-in Audio
Tried uninstalling Alsa and Pulse and reinstalling with the HDMI and TV not connected to the computer but got the same results.
Deleting the .config->pulse folder + logout, login didn't help
Here is the result of a $ aplay -l

Any ideas?
Thanks a lot
