The card does work under MS Windows, after soft reboot into Linux it continues to work, only then tda9887 is loaded as well. I copied the relevant code from the BEHOLD_H6 section to MD7134. The CTX946 TV card doesn't detect a signal after cold boot, seems Signed-off-by: Juergen Gier Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/pci/saa7134/saa7134-cards.c b/drivers/media/pci/saa7134/saa7134-cards.c index 9fac6a9..c520329 100644 --- a/drivers/media/pci/saa7134/saa7134-cards.c +++ b/drivers/media/pci/saa7134/saa7134-cards.c @@ -7798,10 +7798,11 @@ int saa7134_board_init2(struct saa7134_dev *dev) case SAA7134_BOARD_MD7134: { u8 subaddr; - u8 data[3]; + u8 data[3], data1[] = { 0x09, 0x9f, 0x86, 0x11}; int ret, tuner_t; - struct i2c_msg msg[] = {{.addr=0x50, .flags=0, .buf=&subaddr, .len = 1}, - {.addr=0x50, .flags=I2C_M_RD, .buf=data, .len = 3}}; + struct i2c_msg msg[] = {{.addr = 0x50, .flags = 0, .buf = &subaddr, .len = 1}, + {.addr = 0x50, .flags = I2C_M_RD, .buf = data, .len = 3}}, + msg1 = {.addr = 0x61, .flags = 0, .buf = data1, .len = sizeof(data1)}; subaddr= 0x14; tuner_t = 0; @@ -7856,6 +7857,16 @@ int saa7134_board_init2(struct saa7134_dev *dev) } pr_info("%s Tuner type is %d\n", dev->name, dev->tuner_type); + + /* The tuner TUNER_PHILIPS_FMD1216ME_MK3 after hardware */ + /* start has disabled IF and enabled DVB-T.
