I had to replace an apparently dead tv tuner card, and was hoping to get my first taste of HDTV, as there are at least a couple of HD broadcast channels here, so I picked up a Kworld ATSC120 from Newegg a few days ago. I can't tell which mailing list this should go to since there seems to be at least two lists covering this topic, so please forgive the crosspost if it's in error. After reading through both of the mailing lists that this message is destined for (video4linux-list and linux-dvb) , and consulting the video4linux wiki as well as a few other sources, it looks to me like this card *should* work using the driver intended for the Geniatech HDTV Thriller X8000A, as one appears to be a clone of the other. However, I've hit a solid brick wall :( I've downloaded and installed the 2.6.24.2 kernel, and fetched the most recent snapshot of Mauro Carvalho Chehab's repository (which is what seems to be the thing I need) from http://linuxtv.org/hg/~mchehab/cx88-xc2028/ I have compiled and installed the drivers and used the following to start them: ----- modprobe tuner debug=1 modprobe cx88xx card=63 core_debug=1 i2c_debug=1 audio_debug=1 modprobe cx8800 irq_debug=1 video_debug=1 modprobe cx88_alsa ----- This results in the following modules being loaded: ----- rainbird vanessa # lsmod Module Size Used by cx88_alsa 9800 0 cx8800 28956 0 compat_ioctl32 1344 1 cx8800 cx88xx 61864 2 cx88_alsa,cx8800 ir_common 31876 1 cx88xx videobuf_dma_sg 10372 3 cx88_alsa,cx8800,cx88xx videobuf_core 14852 3 cx8800,cx88xx,videobuf_dma_sg btcx_risc 4232 3 cx88_alsa,cx8800,cx88xx tveeprom 14480 1 cx88xx tuner 24716 0 tea5767 6532 1 tuner tda8290 12548 1 tuner tda18271 30536 1 tda8290 tda827x 9924 1 tda8290 tuner_xc2028 19152 1 tuner xc5000 9860 1 tuner videodev 31360 3 cx8800,cx88xx,tuner v4l1_compat 14084 1 videodev tda9887 9092 1 tuner tuner_simple 8840 1 tuner tuner_types 11712 1 tuner_simple mt20xx 11848 1 tuner tea5761 4676 1 tuner v4l2_common 10048 2 cx8800,tuner ----- (Also, nvidia, ali_agp, and agpgart are present) If I also try to load cx8802 right after cx8800, it destablizes my system, locks most of the other modules in (they can no longer be unloaded), and throws a kernel BUG: ----- Feb 21 18:05:31 localhost kernel: cx88[0]/2: cx2388x 8802 Driver Manager Feb 21 18:05:31 localhost kernel: ACPI: PCI Interrupt 0000:02:09.2[A] -> GSI 21 (level, low) -> IRQ 20 Feb 21 18:05:31 localhost kernel: cx88[0]/2: found at 0000:02:09.2, rev: 5, irq: 20, latency: 32, mmio: 0xf6000000 Feb 21 18:05:31 localhost kernel: cx88/2: cx2388x dvb driver version 0.0.6 loaded Feb 21 18:05:31 localhost kernel: cx88/2: registering cx8802 driver, type: dvb access: shared Feb 21 18:05:31 localhost kernel: cx88[0]/2: subsystem: 17de:08c1, board: Geniatech X8000-MT DVBT [card=63] Feb 21 18:05:31 localhost kernel: cx88[0]/2: cx2388x based DVB/ATSC card Feb 21 18:05:31 localhost kernel: zl10353_read_register: readreg error (reg=127, ret==-121) Feb 21 18:05:31 localhost kernel: xc2028: No frontend!

Did some tests: Using kradio, the FM radio tuner receives nothing but static, and only intermittently. kradio refuses to let me tune, claiming that the radio has a range of 0 kHz to 0 kHz. This might be because the driver reports it tuner type 0. The console radio app that comes with xawtv looks like it tune, but there's no audio. Using tvtime with signal detection turned off: * The S-video input works fine right from the start. * The Composite input works, but sits for several seconds in an "overbright" condition when you first switch to it, before dropping down to normal (which it does on its own). Once it gets past that, it seems to work fine. * The analog (?) TV tuner returns nothing but blackness. Tvtime does let me change channels, switch frequency tables, video standards, and so on, but nothing ever appears. Xawtv, mplayer, and VLC all give me the same results as with tvtime (though with VLC I can't tell which input I'm seeing). xine and kaffeine say there are no DVB devices, and both refuse to open any v4l device (did this ever work? how?). * I can't figure out how to get to the digital/ATSC tuner at all (cx8802.ko?) ** I have not tried the card at all under Windows (apparently requires WinXP or Vista, which I do not have) Here is spew from my system log (when the driver is loaded as mentioned above, and without trying to load cx8802.ko), before trying to run any video or radio apps: ----- Linux video capture interface: v2.00 cx88/0: cx2388x v4l2 driver version 0.0.6 loaded ACPI: PCI Interrupt 0000:02:09.0[A] -> GSI 21 (level, low) -> IRQ 20 cx88[0]: subsystem: 17de:08c1, board: Geniatech X8000-MT DVBT [card=63,insmod option] cx88[0]: TV tuner type 71, Radio tuner type 0 cx88[0]: cx88_reset cx88[0]: tveeprom i2c attach [addr=0x50,client=tveeprom] cx88[0]: i2c register ok cx88[0]: Asking xc2028/3028 to load firmware xc3028-v27.fw cx88[0]/0: found at 0000:02:09.0, rev: 5, irq: 20, latency: 32, mmio: 0xf4000000 cx88[0]/0: registered device video0 [v4l2] cx88[0]/0: registered device vbi0 cx88[0]/0: registered device radio0 cx88[0]: set_tvnorm: "NTSC-M" fsc8=28636360 adc=28636363 vdec=28636360 db/dr=28636360/28636360 cx88[0]: set_pll: MO_PLL_REG 0x00fffffe [old=0x00fffffe,freq=28636360] cx88[0]: pll locked [pre=2,ofreq=28636360] cx88[0]: set_tvnorm: MO_INPUT_FORMAT 0x00000001 [old=0x00000007] cx88[0]: set_tvnorm: MO_OUTPUT_FORMAT 0x181f0008 [old=0x181f0008] cx88[0]: set_tvnorm: MO_SCONV_REG 0x00020000 [old=0x00020000] cx88[0]: set_tvnorm: MO_SUB_STEP 0x00400000 [old=0x00400000] cx88[0]: set_tvnorm: MO_SUB_STEP_DR 0x00400000 [old=0x00400000] cx88[0]: set_tvnorm: MO_AGC_BURST 0x00007270 [old=0x00007270,bdelay=114,agcdelay=112] cx88[0]: set_tvnorm: MO_HTOTAL 0x0000038e [old=0x0000038e,htotal=910] cx88[0]: set_scale: 320x240 [TB,NTSC-M] cx88[0]: set_scale: hdelay 0x0038 (width 754) cx88[0]: set_scale: hscale 0x15b3 cx88[0]: set_scale: hactive 0x0140 cx88[0]: set_scale: vdelay 0x0018 cx88[0]: set_scale: vscale 0x1e00 cx88[0]: set_scale: vactive 0x01e0 cx88[0]: set_scale: filter 0x80009 cx88[0]/0: set_audio_standard_BTSC (status: known-good) cx88[0]/0: set_control id=0x980900(Brightness) ctrl=0x7f, reg=0x310110 val=0xff (mask 0xff) cx88[0]/0: set_control id=0x980901(Contrast) ctrl=0x3f, reg=0x310110 val=0x3f00 (mask 0xff00) cx88[0]/0: set_control id=0x980903(Hue) ctrl=0x7f, reg=0x310118 val=0xff (mask 0xff) cx88[0]/0: set_control id=0x980902(Saturation) ctrl=0x7f, reg=0x310114 val=0x5a7f (mask 0xffff) cx88[0]/0: set_control id=0x980909(Mute) ctrl=0x01, reg=0x320594 val=0x40 (mask 0x40) [shadowed] cx88[0]/0: set_control id=0x980905(Volume) ctrl=0x3f, reg=0x320594 val=0x00 (mask 0x3f) [shadowed] cx88[0]/0: set_control id=0x980906(Balance) ctrl=0x40, reg=0x320598 val=0x00 (mask 0x7f) [shadowed] cx88[0]/0: video_mux: 0 [vmux=0,gpio=0x0,0xe3e341,0x0,0x0] cx88[0]/0: cx88: tvaudio thread started cx2388x alsa driver version 0.0.6 loaded ACPI: PCI Interrupt 0000:02:09.1[A] -> GSI 21 (level, low) -> IRQ 20 cx88[0]/1: CX88x/0: ALSA support for cx2388x boards cx88[0]/0: AUD_STATUS: 0x1b2 [mono/no pilot] ctl=BTSC_AUTO_STEREO ----- I'll not post the messages from the cx8802.ko module yet since that driver de-stablizes my system when loaded, but I'll be glad to try again and repost what I find on request.
