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

I'm answering my own question. I found out that the card profile is changing automatically to Digital each time I choose to use a different card (the one from the TV) and come back to the one of the computer. So, it come back to
and I need to change it manually each time to
It is a bit strange to me because the Analog Stereo is marked as "unplugged" but it is working and I'm getting the sound back.
Tried to change the default profile of the card but no success so far. I will open another question about it
