Title:
No more HDMI audio output visible/working snd_hda_intel Cannot turn on
display power on i915
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
All of a sudden, I believe as a result of a kernel upgrade, I cannot
play sound via my HDMI output (television). The option is not listed
anymore in sound settings or VLC. Video output on hdmi works fine. The
internal speakers work fine as well.
I have lenovo ideapad u330p.
