asrock j4205 hdmi audio not working

Asked by tommaso capelli

Hello, I'm having some problems with HDMI audio output on ubuntu 17.04.
My hardware is based on a Asrock j4205 board (http://www.asrock.com/mb/Intel/J4205-ITX/index.us.asp) and is connected to a LG
 47ln5400-za via a hdmi cable.
I'm having a strange behaviour because the audio output is not working when the board boot and much time later. After some hours the audio seems to be working for a while and then it stops working again. I have other devices connected to the tv and I don't have any audio problems.
You can find the output of alsa-info.sh here: http://www.alsa-project.org/db/?f=8cc0a5265b7211c92ccf82ae4e894662827d00f6

If you need more informations I'm available of course.

Thank you in advance

Yes, I'm on 1.30. I've also tried the beta firmware before that. I haven't tried the latest betas. Thank you!
