using vanilla kernel 2.6.15 I fail to get a recent Hauppauge Nova-T board to work. The board is DVB-T 9002 Rev. C176 using the Conexant Tuner CX22702-15 and Decoder CX23882-19. All relevant modules seem to be loaded successfully: $ lsmod Module Size Used by cx88_dvb 8068 0 mt352 6980 1 cx88_dvb or51132 11012 1 cx88_dvb video_buf_dvb 6788 1 cx88_dvb dvb_core 84776 1 video_buf_dvb cx22702 6788 1 cx88_dvb dvb_pll 11012 3 cx88_dvb,or51132,cx22702 cx88_blackbird 21276 0 cx8802 12292 2 cx88_dvb,cx88_blackbird cx8800 33548 1 cx88_blackbird cx88xx 63968 4 cx88_dvb,cx88_blackbird,cx8802,cx8800 video_buf 22212 6 cx88_dvb,video_buf_dvb,cx88_blackbird,cx8802,cx8800,cx88xx ir_common 9860 1 cx88xx tveeprom 15504 1 cx88xx v4l1_compat 14596 1 cx8800 v4l2_common 5952 1 cx8800 btcx_risc 5064 3 cx8802,cx8800,cx88xx videodev 9728 3 cx88_blackbird,cx8800,cx88xx and the syslog does not show any problems on startup: Jan 5 17:51:39 dt2ix kernel: Linux video capture interface: v1.00 Jan 5 17:51:39 dt2ix kernel: cx2388x v4l2 driver version 0.0.5 loaded Jan 5 17:51:39 dt2ix kernel: ACPI: PCI Interrupt 0000:00:09.0[A] -> Link [LNKB] -> GSI 10 (level, low) -> IRQ 10 Jan 5 17:51:39 dt2ix kernel: CORE cx88[0]: subsystem: 0070:9002, board: Hauppauge Nova-T DVB-T [card=18,autodetected] Jan 5 17:51:39 dt2ix kernel: TV tuner 4 at 0x1fe, Radio tuner -1 at 0x1fe Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: Hauppauge model 90002, rev C176, serial# 58619 Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: MAC address is 00-0D-FE-00-E4-FB Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: tuner model is Thompson DTT7592 (idx 76, type 4) Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: TV standards ATSC/DVB Digital (eeprom 0x80) Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: audio processor is None (idx 0) Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: decoder processor is CX882 (idx 25) Jan 5 17:51:39 dt2ix kernel: tveeprom 3-0050: has no radio, has IR remote Jan 5 17:51:39 dt2ix kernel: cx88[0]: hauppauge eeprom: model=90002 Jan 5 17:51:39 dt2ix kernel: input: cx88 IR (Hauppauge Nova-T DVB-T as /class/input/input3 Jan 5 17:51:39 dt2ix kernel: cx88[0]/0: found at 0000:00:09.0, rev: 5, irq: 10, latency: 32, mmio: 0xdd000000 Jan 5 17:51:39 dt2ix kernel: cx88[0]/0: registered device video0 [v4l2] Jan 5 17:51:39 dt2ix kernel: cx88[0]/0: registered device vbi0 Jan 5 17:51:39 dt2ix kernel: cx2388x blackbird driver version 0.0.5 loaded Jan 5 17:51:39 dt2ix kernel: cx2388x dvb driver version 0.0.5 loaded Jan 5 17:51:39 dt2ix kernel: ACPI: PCI Interrupt 0000:00:09.2[A] -> Link [LNKB] -> GSI 10 (level, low) -> IRQ 10 Jan 5 17:51:39 dt2ix kernel: cx88[0]/2: found at 0000:00:09.2, rev: 5, irq: 10, latency: 32, mmio: 0xde000000 Jan 5 17:51:39 dt2ix kernel: cx88[0]/2: cx2388x based dvb card Jan 5 17:51:39 dt2ix kernel: DVB: registering new adapter (cx88[0]).

I may switch channels using xine and tzap, and the audio is switched successfully. Strangely enough I had some success with both klear and xine yesterday using self-compiled Debian Kernel 2.6.12. which gave me video and audio, but today I only get the same application results as above, but a different entry in the syslog: Jan 5 12:44:42 dt2ix kernel: cx22702_set_tps: Autodetecting Jan 5 12:44:44 dt2ix last message repeated 7 times Jan 5 12:44:45 dt2ix kernel: cx88[0]: irq mpeg [0x100000] ts_err?* The message containing 'cx22702_set_tps: Autodetecting' appears very frequently, whereas the one with 'irq mpeg [0x100000] ts_err?*' appeared only once.
