Hi Mikko,
you probably try to use both antenna inputs at once and have the DVB-T
signal on the FM/RF input connector.
The antenna input switching for DVB-T is not yet implemented, because of
a missing API. Currently analog and DVB-T input will work by default on
the Cable/TV connector.
If you want to use both connectors at once without to plug around, using
radio once will switch to the FM/RF connector also for DVB-T until the
other inputs are used again.
Another workaround is to use/abuse a possible mute section for it in the
card's entry from the analog side in saa7134-cards.c.
.radio = {
.name = name_radio,
.amux = TV,
.gpio = 0x0200000,
},
.mute = {
.name = name_mute,
.amux = TV,
.gpio = 0x0200000,
},
},
[SAA7134_BOARD_SEDNA_PC_TV_CARDBUS] = {
Be aware that hardware mute in analog tv apps will switch away the
signal then, mute the mixer instead. Gpio pin 21 is used.
Feel free to improve the issue for your needs.
Cheers,
Hermann
