Heh, I guess You made it clear enough now
I had no such problem with deadbeef, nor with xbmc.
About Deadbeef, the major con for me right now is the lack of support for plugins in 64 bit version, I mean we can compile them on our own but I've runed into the same problems You did.
PPA builds arnt bad though.
If You really want the latest ones install deb packages from their repository
Don't worry about the fact that this package was made for debian, Ubuntu is just a fork of debian after all, Ubuntu made debs will most likely not run on debian system but it works other way around nicely
Additionaly I've found an extremely detailed tutorial about bitperfect audio, even though it was made for windows and describes configuration for a lot of media players it also describes most common problems related to PC audio and propeses few sollutions, such as loading files to RAm for playback, droping buffer to lowest possible value etc.
Unfrortunatly for most of ppl here its written in Polish.
Another tutorial this time in English was made by cambride audio, focuses on windows but gives some insight into DAC's in general:
