My problem is that when I wake up the computer after suspend I don't have audio with HDMI. Well, there is "audio" but it's like playing a song and hearing 1 second every 10 minutes and very distorted. Something strange.
With the speakers of the laptop I don't have problems.
I've been using Ubuntu since 8.04. I had 14.04 in my actual laptop, ThinkPad t450, and there was no problem like this until I upgraded to 16.04.
I have seen this thread but doesn't work for me: no sound after suspend/resume
Also I tried using a script in /etc/pm/sleep.d/
#!/bin/sh
# Script to disable hdmi audio before suspend and restart after wake.
case "${1}" in
suspend|hibernate)
rmmod snd_hda_codec_hdmi
rmmod snd
;;
resume|thaw)
modprobe snd
modprobe snd_hda_codec_hdmi
;;
esac
Still doesn't work with that, maybe I should add things to the script?
lsmod | grep hdmi gives me
snd_hda_codec_hdmi 53248 1

Thanks for the help!
