I'm experiencing what appears to be the same issue.
I have an Acer aspire. Fresh install of Ubuntu 16.04 lts (though same
symptoms on 16.10 & 17.04).
I also experience this from the liveUSB installer.
Due too having a busted screen, I have the hdmi connected to a tv, which
reports the wrong native resolution.
Prior to resizing my screen resolution, hdmi audio appears to work fine.
I can use xrandr to add the correct resolution, but as soon as I change
the hdmi output mode, I loose hdmi audio.
Laptop speaker audio appears to work fine; no headphones available to
test headphone jack.
I've tried the following suggestions without any success:
- pulseaudio -k
- Changing audio output frequency
- dkms suggested above
- commenting out load-module module-switch-on-port-available in
/etc/pulse/default.pa (suggestion from retropie faq)
If any additional details will help, please let me know.
