I've found that after an update, elementary OS no longer shows my intel sound card on system settings and I have no sound. I can only see the HDMI output, which is selected now as the only output. I've reinstalled and reloaded alsa without luck. Also, I've just seen that the audio icon that used to be on wingpanel it's not there.
Can anyone help me out? Thanks.
The output for the alsa script can be seen here.
