Hello, I have a WinTV PVR-150 model 1045, using MythTV and Ubuntu (Hoary) Linux.
I am using NTSC in the US. I'm using ivtv 0.3.3k I'm able to get video over composite just fine with this setup, but audio over composite has alot of noise. The noise seems to happen at the same time as bright spots or flares happen on the video. For example, if the screen is completely white, there will be lots of static noise, but if the screen is darker, the noise will be less. If anyone could point me in the right direction, I would greatly appreciate it. This is my dmesg output from when the driver is started: Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.3.3 (k) loading ivtv: Linux version: 2.6.10-5-686 preempt 686 gcc-3.3 ivtv: In case of problems please include the debug info ivtv: between the START INIT IVTV and END INIT IVTV lines when ivtv: mailing the ivtv-devel mailinglist. ivtv: User specified WinTV PVR 150 card ivtv: Found an iTVC16 based chip ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 10 PCI: setting IRQ 10 as level-triggered ACPI: PCI interrupt 0000:02:08.0[A] -> GSI 10 (level, low) -> IRQ 10 ivtv: XXX PCI device: 0x2530 vendor: 0x8086 tveeprom: Hauppauge: model = 26032, rev = C199, serial# = 7935816 tveeprom: tuner = TCL 2002N 5H (idx = 99, type = 50) tveeprom: tuner fmt = NTSC(M) (eeprom = 0x08, v4l2 = 0x00001000) tveeprom: audio_processor = TDA9850 (type = 3) ivtv: i2c attach [client=tveeprom[50],ok] cx25840: starting probe for adapter ivtv i2c driver #0 (0x10005) cx25840: detecting client on address 0x88 cx25840: writing init values cx25840: FW image '/lib/modules/HcwMakoA.ROM' of size 14264 loaded. cx25840: FW image md5 digest: 3a4803384f749d644ee1f1ca9dcb12fa cx25840: FW image sha1 digest: 2b5e6292b7391c980b93d156cf6b34178ce770f6 cx25840: Status: cx258413 (DEVICE_ID) ivtv: i2c attach [client=cx25840[50],ok] ivtv: Tuner Type 50, Tuner formats 0x00001000, Radio: yes, Model 0x008d1659, Revision 0x00000000 ivtv: NTSC tuner detected ivtv: Radio detected tuner: Ignoring new-style parameters in presence of obsolete ones tuner: chip found at addr 0xc2 i2c-bus ivtv i2c driver #0 ivtv: i2c attach [client=(tuner unset),ok] ivtv: i2c attach [client=wm8775[50],ok] ivtv: Encoder revision: 0x02040024 ivtv: Encoder Firmware may be buggy, use version 0x02040011 ivtv: Configuring WinTV PVR 150 card with 5 streams ivtv: Registered v4l2 device, streamtype 0 minor 0 ivtv: Create DMA stream 0 using 1024 16384 byte buffers 0 kbytes total ivtv: Allocate DMA stream 0 using 1024 16384 byte buffers 16777216 kbytes totalivtv: Registered v4l2 device, streamtype 1 minor 32 ivtv: Create DMA stream 1 ivtv: Allocate DMA stream 1 ivtv: Registered v4l2 device, streamtype 2 minor 224 ivtv: Create DMA stream 2 using 121 34632 byte buffers 0 kbytes total ivtv: Allocate DMA stream 2 using 121 34632 byte buffers 4194304 kbytes total ivtv: Registered v4l2 device, streamtype 3 minor 24 ivtv: Create DMA stream 3 using 455 4608 byte buffers 0 kbytes total ivtv: Allocate DMA stream 3 using 455 4608 byte buffers 2097152 kbytes total ivtv: Registered v4l2 device, streamtype 4 minor 64 ivtv: Create stream 4 ivtv: Allocate stream 4 ivtv: Setting Tuner 50 tuner: type set to 50 (TCL 2002N) by ivtv i2c driver #0 cx25840: decoder set input (6) cx25840: Tuner Input ivtv: ivtv_enc_thread: pid = 3125, itv = 0xd09eef40 cx25840: set audio: 0x01 ivtv: Switching standard to NTSC. cx25840: decoder set norm NTSC cx25840: set audio: 0x01 ivtv: Initialized WinTV PVR 150, card #0 ivtv: ==================== END INIT IVTV ==================== Here is what I have in my modules.conf: ### update-modules: start processing /etc/modutils/ivtv # WinTV PVR-150 #alias char-major-81 videodev #alias char-major-81-0 ivtv #options ivtv ivtv_debug=1 cardtype=6 # ivtv modules setup alias char-major-81 videodev alias char-major-81-0 ivtv options ivtv ivtv_debug=1 mpg_buffers=90 cardtype=6 #w/ivtv 0.1.9 options saa7127 enable_output=1 output_select=0 options tuner type=2 # NTSC tuner #options msp3400 once=1 simple=1 options cx25840 no_black_magic=1 audiofmt=0x20 options wm8775 mixer=2 #add below ivtv msp3400 saa7115 saa7127 tuner add above ivtv lirc_dev lirc_i2c lirc_sir add above ivtv ivtv-fb ### update-modules: end processing /etc/modutils/ivtv ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
