I am running an athlon ii 945 with a hauppauge wintv 1600 capture card. I have a version of mythtv installed (0.24) in which I downloaded the latest V4L-DVB Device Drivers from git://linuxtv.org/media_build.git, built them, and then installed. Everything is up to date with the software packages. The video records perfectly fine but the audio is missing. The backend log has the following indicators of problems: 2012-02-29 22:30:28.722 AFD Warning: ScanATSCCaptionStreams() called with no PMT 2012-02-29 22:30:28.763 AFD: Opened codec 0x7f7180007f30, id(MPEG2VIDEO) type(Video) 2012-02-29 22:30:28.797 AFD: codec MP2 has 2 channels 2012-02-29 22:30:28.830 AFD: Opened codec 0x7f718000abe0, id(MP2) type(Audio) 2012-02-29 22:30:28.951 [mpeg2video @ 0x7f719986c700]warning: first frame is no keyframe 2012-02-29 22:30:29.016 [mpeg2video @ 0x7f719986c700]warning: first frame is no keyframe 2012-02-29 22:35:12.770 [mpeg2video @ 0x7f719986c700]00 motion_type at 28 10 2012-02-29 22:35:12.815 [mpeg2video @ 0x7f719986c700]Warning MVs not available 2012-02-29 22:35:12.859 [mp2 @ 0x7f719986c700]incomplete frame 2012-02-29 22:35:12.899 AFD Error: Unknown audio decoding error In the syslog I am seeing entries (a log of them) like this: Feb 29 22:29:56 bifrosttv kernel: [ 1154.739451] cx18-0: Skipped encoder IDX, MDL 442, 2 times - it must have dropped out of rotation Feb 29 22:29:56 bifrosttv kernel: [ 1154.739459] cx18-0: Skipped encoder IDX, MDL 443, 2 times - it must have dropped out of rotation Feb 29 22:29:56 bifrosttv kernel: [ 1154.739465] cx18-0: Skipped encoder IDX, MDL 444, 2 times - it must have dropped out of rotation Feb 29 22:29:56 bifrosttv kernel: [ 1154.739472] cx18-0: Could not find MDL 438 for stream encoder IDX Feb 29 22:29:56 bifrosttv kernel: [ 1154.739478] cx18-0: Could not find MDL 441 for stream encoder IDX Feb 29 22:30:00 bifrosttv kernel: [ 1158.736285] cx18-0: Skipped encoder IDX, MDL 444, 1 times - it must have dropped out of rotation Feb 29 22:30:00 bifrosttv kernel: [ 1158.736325] cx18-0: Could not find MDL 441 for stream encoder IDX Feb 29 22:30:00 bifrosttv kernel: [ 1158.736335] cx18-0: Could not find MDL 442 for stream encoder IDX Feb 29 22:30:00 bifrosttv kernel: [ 1158.736431] cx18-0: Could not find MDL 443 for stream encoder IDX Feb 29 22:30:00 bifrosttv kernel: [ 1158.736437] cx18-0: Could not find MDL 444 for stream encoder IDX Feb 29 22:30:00 bifrosttv kernel: [ 1158.736475] cx18-0: Could not find MDL 442 for stream encoder IDX Does anyone have suggestions or ideas I can try? -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
