Title:
HDMI audio and AC3 audio output does not work in Intel NUC
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have a Intel NUC7PJYH with HDMI video and audio to a monitor. Also I use
SPDIF ac3 output (having libasound2-plugins-extra). This always worked fine.
Since a few weeks, HDMI and ac3 is gone. I.e. 'aplay -l' does not show HDMI any
more.
Now I found out that if I boot without any usb devices connected (without
webcam,mouse,keyboard), it works and I have the HDMI audio output.
Does this point into a IRQ problem?
Attached find the apport and the alsa-info when HDMI was present and when it
was not present.
