If you kill the Mythbackend, can you control it with v4l2-ctl ? I suspect it's a MythTV problem. Here's when I'm set to the tuner: $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 48 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC $ v4l2-ctl -c audio_sampling_frequency=0 $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 44.1 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC $ v4l2-ctl -c audio_sampling_frequency=2 $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 32 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC $ v4l2-ctl -c audio_sampling_frequency=1 $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 48 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC Here's with using SVideo1: $ v4l2-ctl -i1 Video input set to 1 (S-Video 1) $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 48 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC $ v4l2-ctl -c audio_sampling_frequency=2 $ v4l2-ctl --log-status | grep Audio: cx18-0: Audio: 32 kHz, MPEG-1/2 Layer II, 224 kbps, Stereo, No Emphasis, No CRC Regards, Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
