I am using an tower pc with an Ati RX 480, which worked fine with the proprietary driver including the sound via HDMI on the screen using Ubuntu 16.04. After I upgraded to Ubuntu 16.10, sound stopped working. Furthermore the fonts and the ubuntu logo during the boot process are displayed wrong on my big screen (3440 x 1440), while my other screen (FullHD) has normal fonts and the normal logo.
Sound via the normal sound output is working.
The troubleshooting from https://help.ubuntu.com/community/SoundTroubleshootingProcedure unfortunately did not help: Deleting
pulseaudio and so on did not change anything. The diagnostic command from step 4 returned https://nopaste.me/view/671d3225 Muting and umuting the
S/PDIF 1, ... and
S/PDIF 5 did not change anything. There are no bars displayed in alsamixer for the hdmi audio card, only the
S/PDIF-entries with 00 or MM - may this be a problem?
Is there any known bug for this, or a workaround? I tried to reinstall the proprietary driver, but this returned the following output:
dagere@dagere-desktop:~/Downloads/amdgpu-pro-driver$ ./amdgpu-pro-install tee: /etc/aptsources.list.d/amdgpu-pro.list: Datei oder Verzeichnis nicht gefunden deb file:/var/opt/amdgpu-pro/ ./
/etc/apt/sources.list.d/amdgpu-pro.list is existing, is it safe to just change the directoy in the install-script?
Has anyone experience with getting hdmi-sound working with the opensource-driver delivered with ubuntu 16.10 or with getting the proprietary driver installed in ubuntu 16.10?
While the newest amd-driver is installable on ubuntu 16.10, this does not solve the sound issue. Furthermore, even if I install the 4.9.11, as far as I see the newest kernel (like described in How to update kernel to the latest mainline version without any Distro-upgrade? with
dpkg -i *.deb), sound stays unusable.
Since in 16.04 sound was working correctly, I tried installing it in parallel.
In 16.04, eclipse scrolling is slow (and requires much CPU), which imho seems like the driver is not working correctly. I found https://community.amd.com/thread/203889 which recommends MESA-update, linux-firmeware update and kernel-update from Ubuntu 16.04. I tried this one, but with any kernel (188.8.131.52, 4.9.11-040911 and 4.10.0-041000) the problem in eclipse is still appearing. Nevertheless, with a newer kernel the sound stops working. So now with 16.04, sound works and eclipse not, and with 16.10, eclipse works, but sound not. (Setting
--launcher.GTK_version 2 in eclipse does not change anything). Is there any workaround for this, either to get the sound working in 16.10 or the graphics working in 16.04?
EDIT 3 Still not working in Ubuntu 17.04 with Kernel 4.10. I'd still be glad about other suggestions.
