Ubuntu :: 10.10 - Sound While Playing Games Under WINE

I am having sound issues while playing some games under WINE. for this I will use World of Warcraft as it has options for different sound engines. The problem is that I will have sound running fine for a while after a fresh reboot. It will seem fine for a good half hour to an hour and then suddenly it will stop. It will still be present in the applications list in sound preferences listed as 'ALSA plug-in [wine-preloader]'. muting/unmuting and adjusting the slider has no effects. Enabling and disabling sound in the game also has no effects. Here is what I have tried thus far to try to remedy it:

tried all of the various sound options in winecfg (some simply don't produce any sound at all on a fresh reboot - OSS, for instance) tried with and without padsp tried the various sound engines in Config.wtf tried WINE from the Ubuntu repositories and the developer's PPA tried lowering the sample rate and the bits per sample in the audio tab of winecfg tried fiddling with the sound preferences applications controls I am not adventurous enough to try to install OSSv4 so that doesn't seem like an option for me. it is important to note that sounds not coming from WINE function as normal even while WINE is producing no sounds.
