Does CrossOver work with aRts (KDE)?
As mentioned below, the sound drivers will often only allow a single application to play sounds. A twist on this theme is that, by default, KDE (2.2 and greater) uses a new sound system called aRts which may already be using the OSS driver without your knowledge. Under this system, applications are supposed to send their audio to a ‘sound daemon’ which mixes them in realtime and sends the result over to the OSS or ALSA driver. This lets multiple applications play sounds simultaneously but also means they cannot play sounds directly anymore which is what CrossOver is doing.
