Public bug reported: The card (WinTV PCI, model 34519 Rev J189, using the Conexant CX23881-19 decoder chip) supports analog TV and FM radio, both of which I confirmed to be working in a Windows XP machine. TV also works on linux (Ubuntu 9.10, kernel version 2.6.31-14-generic), but the FM radio tuner doesn't work properly.
The device file /dev/radio0 is there, but every radio application I tried produces only a hissing noise on every frequency and doesn't find any channels. When I start "radio -c /dev/radio0" (from the "radio" package), the tuner frequency shown initially is "2147.", whatever this is supposed to mean. In this setting, it is noticable that there is some radio signal there - it is very faint and unintelligible, but you can tell that there are people speaking. As soon as I try to change the frequency though, a hissing noise appears which sounds exactly the same on each and every frequency. Also, on no frequency I can set up there is anything resembling the unintelligible speech heard in the tool's initial setting. I suspect that the code to change the tuner frequency doesn't work correctly for this card. The dmesg output from the cx88 module reads as follows: [ 12.180925] cx88/0: cx2388x v4l2 driver version 0.0.7 loaded [ 12.181005] cx8800 0000:03:06.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 [ 12.181491] cx88[0]: subsystem: 0070:3401, board: Hauppauge WinTV 34xxx models [card=1,autodetected], frontend(s): 0 [ 12.181497] cx88[0]: TV tuner type -1, Radio tuner type -1 [ 12.642401] tuner 0-0043: chip found @ 0x86 (cx88[0]) [ 12.815426] tda9887 0-0043: creating new instance [ 12.815434] tda9887 0-0043: tda988[5/6/7] found [ 12.823106] tuner 0-0061: chip found @ 0xc2 (cx88[0]) [ 12.862253] tveeprom 0-0050: Hauppauge model 34519, rev J189, serial# 7873365 [ 12.862260] tveeprom 0-0050: tuner model is TCL MFPE05 2 (idx 89, type 38) [ 12.862266] tveeprom 0-0050: TV standards PAL(B/G) PAL(I) SECAM(L/L') PAL(D/D1/K) (eeprom 0x74) [ 12.862271] tveeprom 0-0050: audio processor is CX881 (idx 31) [ 12.862275] tveeprom 0-0050: has radio [ 12.862279] cx88[0]: hauppauge eeprom: model=34519 [ 13.079345] tuner-simple 0-0061: creating new instance [ 13.079355] tuner-simple 0-0061: type set to 38 (Philips PAL/SECAM multi (FM1216ME MK3)) [ 13.082911] input: cx88 IR (Hauppauge WinTV 34xxx as /devices/pci0000:00/0000:00:1e.0/0000:03:06.0/input/input6 [ 13.083204] cx88[0]/0: found at 0000:03:06.0, rev: 5, irq: 19, latency: 32, mmio: 0xdd000000 [ 13.083234] IRQ 19/cx88[0]: IRQF_DISABLED is not guaranteed on shared IRQs [ 13.083543] cx88[0]/0: registered device video0 [v4l2] [ 13.083825] cx88[0]/0: registered device vbi0 [ 13.087668] cx88[0]/0: registered device radio0 [ 13.336262] EXT4-fs (dm-0): internal journal on dm-0:8 [ 13.640625] cx2388x alsa driver version 0.0.7 loaded [ 13.640720] cx88_audio 0000:03:06.1: PCI INT A -> GSI 19 (level, low) -> IRQ 19 [ 13.640736] IRQ 19/cx88[0]: IRQF_DISABLED is not guaranteed on shared IRQs [ 13.640783] cx88[0]/1: CX88x/0: ALSA support for cx2388x boards ProblemType: Bug Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jensi 2497 F.... pulseaudio /dev/snd/controlC1: jensi 2497 F.... pulseaudio CRDA: Error: [Errno 2] No such file or directory Card0.Amixer.info: Card hw:0 'I82801DBICH4'/'Intel 82801DB-ICH4 with CMI9739 at irq 17' Mixer name : 'C-Media Electronics CMI9739' Components : 'AC97a:434d4961' Controls : 43 Simple ctrls : 27 Card1.Amixer.info: Card hw:1 'CX8811'/'Conexant CX8811 at 0xde000000' Mixer name : 'CX88' Components : '' Controls : 3 Simple ctrls : 2 Card2.Amixer.info: Card hw:2 'UART'/'MPU-401 UART at 0x330, irq 5' Mixer name : '' Components : '' Controls : 0 Simple ctrls : 0 Card2.Amixer.values: Date: Thu Nov 5 20:02:42 2009 DistroRelease: Ubuntu 9.10 HibernationDevice: RESUME=UUID=16c3eedd-2816-4ce6-921b-86be5df3aa2b IwConfig: lo no wireless extensions. eth0 no wireless extensions.
