Okay, the "fallback" works -- recordings made with it do have good audio. And.. my hypothesis appears to be true thus far: once the audio fails, requiring the fallback, it stays failed until the driver is reloaded. Every subsequent recording made (after a "fallback") also experiences the fallback. This is with a good channel, with good audio. Subsequent recordings using the exact same channel. Weird, eh. I wonder how to discover the real cause? Good workaround, though! Thanks. -- Mark Lord Real-Time Remedies Inc. mlord@pobox.com
