It appears I owe everyone here an apology. It seems that under the audio tab in winecfg, choosing a specific output device, in this case my usb headset, results in pulseaudio not being used. However, setting system default does allow pulseaudio to be used. Tried under wine 1.3.31 under a chroot setup, and 1.3.32 under my installed ubuntu. Thanks all for the suggestions. Seems my user name is quite fitting after all [Embarassed] However, I would have thought that pulseaudio would have been used whatever audio device I had selected, so I'm still a little confused.
