Unfortunately it doesn't. This is the output of v4l2-ctl --log-status with your update after make, make install, make unload, modprobe cx18, tuning a channel, and doing three test captures. cx18-0: ================= START STATUS CARD #0 ================= tveeprom 0-0050: Hauppauge model 74021, rev C1B2, serial# 1441469 tveeprom 0-0050: MAC address is 00-0D-FE-15-FE-BD tveeprom 0-0050: tuner model is TCL M2523_5N_E (idx 112, type 50) tveeprom 0-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 0-0050: audio processor is CX23418 (idx 38) tveeprom 0-0050: decoder processor is CX23418 (idx 31) tveeprom 0-0050: has no radio, has IR receiver, has IR transmitter cx18-0: Video signal: present cx18-0: Detected format: NTSC-M cx18-0: Specified standard: NTSC-M cx18-0: Specified video input: Composite 7 cx18-0: Specified audioclock freq: 48000 Hz cx18-0: Detected audio mode: mono cx18-0: Detected audio standard: no detected audio standard cx18-0: Audio muted: yes cx18-0: Audio microcontroller: running cx18-0: Configured audio standard: automatic detection cx18-0: Configured audio system: BTSC cx18-0: Specified audio input: Tuner (In8) cx18-0: Preferred audio mode: stereo cs5345 0-004c: Input: 1 cs5345 0-004c: Volume: 0 dB tuner 1-0061: Tuner mode: analog TV tuner 1-0061: Frequency: 163.25 MHz tuner 1-0061: Standard: 0x00001000 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: MPEG-2 Program Stream cx18-0: VBI Format: No VBI cx18-0: Video: 720x480, 30 fps cx18-0: Video: MPEG-2, 4x3, Variable Bitrate, 6000000, Peak 8000000 cx18-0: Video: GOP Size 15, 2 B-Frames, GOP Closure cx18-0: Audio: 48 kHz, Layer II, 224 kbps, Stereo, No Emphasis, No CRC cx18-0: Spatial Filter: Manual, Luma 1D Horizontal, Chroma 1D Horizontal, 0 cx18-0: Temporal Filter: Manual, 8 cx18-0: Median Filter: Off, Luma [0, 255], Chroma [0, 255] cx18-0: Status flags: 0x00200001 cx18-0: Stream encoder MPEG: status 0x0000, 0% of 2016 KiB (63 buffers) in use cx18-0: Stream encoder YUV: status 0x0000, 0% of 2048 KiB (16 buffers) in use cx18-0: Stream encoder PCM audio: status 0x0000, 0% of 1008 KiB (63 buffers) in use cx18-0: Read MPEG/VBI: 7720960/0 bytes cx18-0: ================== END STATUS CARD #0 ================== > > BTW, Did the cx18 driver ever work properly for tuner audio for you > before? > I bought the card on July 27 from a friend who has had it sitting in his closet for a year and a half. This is the first time anybody has ever installed it in a system and tried to get it working. I'm starting to wonder if maybe I have a defective card. I suppose I could try installing it in a windows system and see if I can get audio. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
