Comment 3 for bug 502375

You can fix winmm.dll problem, without recompiling the kernel, by setting your audio output to oss in winecfg. Run winecfg, switch to audio tab, select oss output. If you can't access winecfg, please try the following steps: disable any soundcard which is giving problem (i.e. remove usb soundcards, disable internal ones from bios), then run winecfg, set the right output, enable all your soundcards, reboot. For me, everything has worked fine since I took these steps. I'm running ubuntu karmik with kernel 2.6.31-9-rt #152-Ubuntu x86_64, internal soundcard: intel hda, external soundcard: hercules mk2 (usb).
