--- Comment #7 from rocko rockorequin@hotmail.com 2010-07-18 05:43:01 --- Audio now works for me with wine1.2 using ALSA and 'Windows7' in winecfg, and dsound no longer needs patching to get it to initialise. (However, it doesn't work 'out-of-the-box' - CoD5 fails to initialise with a default wine installation: you need to install the XAudio_2 dll and/or DirectX9 as per the how-to in http://appdb.winehq.org/objectManager.php?sClass=version&iId=14475.)
