Hello,
So for now I think i solved the high CPU problem.... Here's how:
The command that was causing the problem was 'midori -p -e Fullscreen html://localhost'. According to top this was process number 728.
The file /proc/728/cmdline contained this command so I just commented it out and rebooted.
Now I have no problems with radio streams any more and my system is running with much less CPU and memory usage.
I have to say that I am just a novice at all this stuff and that this was the result of just exploring root directory folders and the top output. As such I have no idea why this has worked! If you can explain that would be great.
Also if there's any chance I've broken anything else by altering this file please let me know.
