Sporatic missing sound on startup

[pandaphil]

Enjoying the game so far. Definately a lot harder than it looks.

Minor sound problem. I'm playing using a pair of usb gamer headphones, and sometimes when I start the game I get no audio. Closing and restarting the game once or twice fixes the problem, but its still a minor inconvenience. Running XP SP3 and I've downloaded the latest version of OpenAL and rebooted with no difference.
Any idea whats up?

Glad to hear you're enjoying the game so far, pandaphil.

From your log, it looks like the error is occurring internally to OpenAL initialization -- can you please verify you have the latest drivers for your sound and motherboard HW?

Thanks,
Dave
