Please try to use a DVD player or camera on the S-Video or CVBS analog video input and L/R line in audio input, instead of the tuner. (Use 'v4l2-ctl' on /dev/videoN to set the input.) That will narrow down whether or not this is an analog tuner problem. Obviously check cables and connectors for breaks, including inspecting, as best you can, the connector on the HVR-1600 itself. With analog problems, I always encourgae people to double-check their cable plant: http://ivtvdriver.org/index.php/Howto:Improve_signal_quality Also as a temporary test, you may want to run a line from the analog source straight to the HVR-1600 with no splits, to see if things start to work. > v4l2-ctl --log-status shows video signal not present > > Status Log: > > > > cx18-0: ================= START STATUS CARD #0 ================= > > cx18-0: Version: 1.5.1 Card: Hauppauge HVR-1600 > tveeprom 4-0050: Hauppauge model 74041, rev C6B2, serial# 5267091 > tveeprom 4-0050: MAC address is 00:0d:fe:50:5e:93 > tveeprom 4-0050: tuner model is TCL M2523_5N_E (idx 112, type 50) > tveeprom 4-0050: TV standards NTSC(M) (eeprom 0x08) > tveeprom 4-0050: audio processor is CX23418 (idx 38) > tveeprom 4-0050: decoder processor is CX23418 (idx 31) > > tveeprom 4-0050: has no radio, has IR receiver, has IR transmitter > > cx18-0 843: Video signal: not present > > cx18-0 843: Detected format: NTSC-M > cx18-0 843: Specified standard: NTSC-M > cx18-0 843: Specified video input: Composite 7 > cx18-0 843: Specified audioclock freq: 48000 Hz > cx18-0 843: Detected audio mode: mono > cx18-0 843: Detected audio standard: no detected audio standard > cx18-0 843: Audio muted: yes > cx18-0 843: Audio microcontroller: running > cx18-0 843: Configured audio standard: automatic detection > cx18-0 843: Configured audio system: BTSC > cx18-0 843: Specified audio input: Tuner (In8) > > cx18-0 843: Preferred audio mode: stereo cx18-0 > > gpio-reset-ctrl: GPIO: direction 0x00003001, value 0x00003001 > > tuner 5-0061: Tuner mode: analog TV > tuner 5-0061: Frequency: 67.25 MHz 67.25 MHz is US analog broadcast channel 4 (the default channel to which the cx18 driver sets the tuner upon module load). Make sure you have an analog signal on channel 4. Otherwise tune the channel freq using 'ivtv-ctl' or 'v4l2-ctl' on /dev/videoN. If using 'v4l2-ctl', analog frequency tables for North America are here: http://en.wikipedia.org/wiki/North_American_broadcast_television_frequencies http://en.wikipedia.org/wiki/North_American_cable_television_frequencies > tuner 5-0061: Standard: 0x00001000 > cs5345 4-004c: Input: 1 > cs5345 4-004c: Volume: 0 dB > cx18-0: Video Input: Tuner 1 > > cx18-0: Audio Input: Tuner 1 > cx18-0: GPIO: direction 0x00003001, value 0x00003001 > cx18-0: Tuner: TV > cx18-0: Stream Type: MPEG-2 Program Stream > cx18-0: Stream VBI Format: No VBI > cx18-0: Audio Sampling Frequency: 48 kHz cx18-0: Audio Encoding: MPEG-1/2 Layer > > II cx18-0: Audio Layer II Bitrate: 224 kbps cx18-0: Audio Stereo > > Mode: Stereo cx18-0: Audio Stereo Mode Extension: Bound 4 inactive > > cx18-0: Audio Emphasis: No Emphasis cx18-0: Audio CRC: No CRC > > cx18-0: Audio Mute: false cx18-0: Video Encoding: MPEG-2 cx18-0: > > Video Aspect: 4x3 cx18-0: Video B Frames: 2 cx18-0: Video GOP Size: > > 15 cx18-0: Video GOP Closure: true cx18-0: Video Bitrate Mode: > > Variable Bitrate cx18-0: Video Bitrate: 6000000 cx18-0: Video Peak > > Bitrate: 8000000 cx18-0: Video Temporal Decimation: 0 cx18-0: Video > > Mute: false cx18-0: Video Mute YUV: 32896 cx18-0: Spatial Filter > > Mode: Manual cx18-0: Spatial Filter: 0 cx18-0: Spatial Luma Filter > > Type: 1D Horizontal cx18-0: Spatial Chroma Filter Type: 1D > > Horizontal cx18-0: Temporal Filter Mode: Manual cx18-0: Temporal > > Filter: 8 cx18-0: Median Filter Type: Off cx18-0: Median Luma > > Filter Minimum: 0 inactive cx18-0: Median Luma Filter Maximum: 255 > > inactive cx18-0: Median Chroma Filter Minimum: 0 inactive cx18-0: > > Median Chroma Filter Maximum: 255 inactive cx18-0: Insert > > Navigation Packets: false cx18-0: Status flags: 0x00200001 cx18-0: > > Stream encoder MPEG: status 0x0000, 0% of 2048 KiB (64 buffers) in > > use cx18-0: Stream encoder YUV: status 0x0000, 0% of 2025 KiB (20 > > buffers) in use cx18-0: Stream encoder VBI: status 0x0000, 0% of > > 1015 KiB (20 buffers) in use cx18-0: Stream encoder PCM audio: > > status 0x0000, 0% of 1024 KiB (256 buffers) in use cx18-0: Read > > MPEG/VBI: 0/0 bytes cx18-0: ================== END STATUS CARD #0 > > ================== > > I have been modprobing the cx18 in /etc/rc.local > # This section is > added to make the HVR1600 Analog Audio Work > > # service mythbackend stop modprobe -vv cx18 modprobe -v cx18_alsa > > # service mythbackend start Be advised, for a delayed load of the cx18 module, you must blacklist it in /etc/modprobe.d/*, otherwise it will get loaded for you anyway. There is no need to modprobe cx18-alsa, the cx18 driver should request/cause that to load automatically if it exists.
