<div dir="ltr">I recently upgraded my PVR-500 system to Fedora 9 and myth 0.21-192 from atrpms. I'm having intermittently scratchy audio on both tuners. The bad audio can come from either tuner. If I stop the recording and immediately switch to watching the input from the tuner, the audio has always been fine. I've watched the videos on a separate machine without the bad audio, so the problem must occur in the recording or encoding.<br>
<br>dmesg reports many ivtv* errors:<br>ivtv0: All encoder VBI stream buffers are full. Dropping data.<br>ivtv0: Cause: the application is not reading fast enough.<br>ivtv1: All encoder MPG stream buffers are full. Dropping data.<br>
ivtv1: Cause: the application is not reading fast enough.<br><br>cat /proc/interrupts shows what appear to be conflicts:<br> 17: 27482432 IO-APIC-fasteoi Intel ICH5, ivtv0<br> 18: 19053098 IO-APIC-fasteoi uhci_hcd:usb4, ata_piix, ivtv1<br>
<br>Are the interrupts the problem? The mailing list archive directs me to check the interrupts, but I can't find anything to help me determine whether I have an interrupt problem, or how to fix it.<br></div>
