[Wine] Sins of a Solar Empire sound & font problems

[Nameless]

I am trying to run Sins of a Solar Empire (http://appdb.winehq.org/objectManager.php?sClass=application&iId=6653), and most reports say that it is playable, with the exception of large fotns. However, I an having sound problems. 

Sound is stuttering in-game. I tried fiddling around with the sound options in winecfg, but nothing solved the problem (although Emulation instead of Full hardware acceleration made thijngs better). Is there anything else I can try? Anyone else who has played the game and care to help?

Also, text in-game appears mostly corrupt for me, not large. There are some texts which appear fine, and all others are just random lines. 

I am running it on Ubuntu 7.10, with an ATi X1650 card, the latest fglrx drivers, and my sound card is the on-board Realtek ALC888 (or something like that).
