Is the audio OK before you lose it? Is there any stuttering or does it get out of synch with the video? Are you recording uncompressed audio or MP3? > The errors in the mythbackend log are of the form: > 2005-08-16 21:37:30.298 NVR: Only read -1 bytes of 16384 bytes from > '/dev/dsp1 > read audio: Input/output error Sounds like the audio buffer on the hardware is getting overrun, which causes the audio pipe to lock up. Usually this happens because of bus errors or because the host CPU can't service the audio pipe fast enough. What video bitrate are you running? Is the convertx connected to a USB 2.0 port? Do your other USB devices work OK? Have you tried swapping out the USB cable, or hub, if you're using one? -Nathan
