Hey. First of all I want to thank all of you for your help. This thread helped me out many times already. Today I have a few issued I cant solve myself.
About a week ago I wanted to do a full new installation of Ubuntu 14.04 since my old 13.10 didnt work very well.
The XBMC-session is started via lightdm autologin, compiz is not running with xbmc, the /etc/init/xbmc.conf file was not created, puleaudio was purged, I modified /etc/default/grub to "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1 radeon.dpm=1 radeon.hw_i2c=1"" and I disabled backing store in /usr/share/xsessions/XBMC.desktop "Exec=xbmc-standalone -- -bs"
Here are my issues ordered by priority
Im fighting with them for about a week now and have tried countless how-tos which broke my system completely a dozen times so it would be nice if we could get it to work without a new installation...
With my old Ubuntu 13.10 and your how-to i had none of these problems.
1.
720p videos work fantastic, even with DTS.
In 1080p videos begin to stutter and in some scenes the framerate drops to around 12 FPS. Audio plays fine, CPU usage is around 5-20%.
Non-HD videos have green and black artefacts.
[EDIT] sometimes the 5.1 center line is missing/not playing
2.
After video playback in the XBMC menu the CPU goes up to 100% all the time, before playback it is around 30%.
[EDIT] seems to be some addon loading stuff, it has fixed itself.
3.
I dont get sound over HDMI, I have to use SPDIF to get any sound. It is okay for now but it would be nice to have everything to work over HMDI.
4.
Some issues with PVR stopping playback and now running stable, but this does not belong here I guess so I wont get deeper into this.
