Summary: C4 demo fails on startup due to missing XAudio2?
           Product: Wine

I tried downloading the C4 demo,
190214c5cb8b7952583932860147ff287357ce46  C4Demo1.5.9.zip
and running C4. It dies fairly quickly with
err:ole:CoGetClassObject class {03219e78-5bc3-44d1-b92e-f63d89cc6526} not
registered
and a dialog box saying no audio could be found.
A quick search shows that UUID is associated with XAudio2.
"sh winetricks directx9-beta" worked around that.
