I installed Retroarch on my Lubuntu 14.10 system lastnight and it worked like a dream.
I was playing New Super Mario Bros using the Nintendo DS core and it was great.
This morning I went to go on it again and now it goes to the title screen then crashes. After it crashes it takes the sound with it too so nothing has sound.
When looking through the terminal while its running this is what i get
DeSmuME 0.9.11 svn0 x64-JITAttempting change to 3d core to: SoftRasterizer SoftRast Initialized with cores=1 RetroArch [WARN] :: rarch_log_libretro :: [libretro WARN] :: Save directory is not defined. Fallback on using SYSTEM directory ...

I hope I can fix this problem as I really want this DS emulator to work. It runs better than using the stand alone DeSmuME emulator.
