In case you’ve tried to upgrade your XBMC application using the official repositories from “team-xbmc” you may have already noticed that the rar support was disabled. This means that you won’t be able to play movies or open subtitles without extracting it first.
You have two options to fix this issue:
a) You compile the source code and enable the non free features.
b) You use a precompiled version made by someone else.
Fortunately there are good news for those who want option b. A guy named Nathan runs a repository where you can download XBMC with these features enabled. Just add his repository to your sources list and you are ready to go.
sudo add-apt-repository ppa:nathan-renniewaldock
apt-get install xbmc
You can also manually check out his repository here.
This is probably a common problem among all the people trying to get audio over HDMI under Linux using an EN210 graphics card (or similar).
Even though the HDMI may appear in your available cards listed in proc (/proc/asound/cards) you will probably see that you cannot find it using the aplay utility. Just check it running the command “aplay -l”. The HDMI device isn’t listed here isn’t it?
The reason for this issue is related to the ALSA driver version 1.0.21 (or older) which is quite buggy for these graphics cards.
You can check which version you are using by executing the following command:
If you get a version older than 1.0.21 then you need to upgrade it. You can check your favourite distribution’s repository for an update or you can try to compile it from source code.
