Here is a bit more info with entries from the Syslog. More experimentation has shown that there is some sort of relationship with firefox.... a recent update seemed to fix things somewhat
With Firefox up, but not playing sounds after a clean reboot all audio devices work, but once sound is played within firefox all audiodevices fail shutting down firefox releases whatever lock is own there and the devices can play again, however after restarting firefox the audio on firefox fails and so does the audio on the sound devices.... here tail of the syslog entry for those events.
