Sound Blaster X-Fi stuttering on Linux Mint KDE 14

Dear fellow Linux users,
I have an issue with using my Creative Sound Blaster X-Fi mX Gamer sound card in Linux Mint KDE 14 64-bit - overall the sound works (and when it works, it works very well), but in some applications (e.g. Skype, some emulators like PCSX2) the sound stutters and skips. Also, in addition to that, the stuttering becomes apparent in all applications when minimizing/maximizing windows or starting applications - for instance, if I open Firefox or minimize/maximize a window or two while VLC is playing music, some noise may be heard or the sound may skip a beat or click. Upon investigation the console shows this message when stuttering occurs (if the app is launched through terminal):

ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred
After doing a search online and looking into some suggestions I narrowed down the issue to my sound card (seems like the sound doesn't/shouldn't stutter if I used, for instance, on-board audio, though I didn't try that), but I haven't found any conclusive evidence as to what can be done to remedy the problem *and* keep using my X-Fi card. So far I tried adding this to my alsa-base.conf:

options snd-hda-intel model=5stack
(I don't think it has done anything)
And I also tried executing this terminal command to increase my ALSA buffer size:

echo 32768 | sudo tee /proc/asound/card0/pcm1p/sub0/prealloc
which, I believe, also did nothing, really, because the sound is still the same (stutters when it stutters).

Is there anything else that can be attempted here, or is X-Fi on Linux a lost cause? If any logs are necessary, please let me know which ones and how to obtain them, I'd be happy to cooperate. Thank you very much in advance for help.
