SB 3.0.3 sound issue

Ever since installing the latest version of Squawkbox, I've started having a problem where after a couple of hours, I'll lose *all* sounds from SB--voice, the clicks and dings on text chat, the noises when I tune a controller's frequency, everything. If I switch my sound output from "Wave" to "DirectSound", I get the sound back, but it's broken and choppy while I'm in the cockpit. Switching back to "Wave" loses the sound again.I'm using the built-in nVidia sound on my Asus A7N8X Deluxe motherboard. This only seemed to start happening after I installed SB3.0.3 over top of my old SB3 installation. Anybody have any ideas?Lewis "Moose" GregoryRichmond, Virginia
