I appear to have the same here on an upgrade to Ubuntu Karmic 32bit. It tends to happen more often with multiple audio sources playing simultaneously, and particularly with high bitrate FLAC audio. The app (Rhythmbox/Listen) will typically run with 100pc CPU utilisation thereafter, albeit successfully.
Sound card is a PCI Creative X-Fi XtremeAudio running under CA0106.
