Tuner=69 covers a lot of tuners with TexasInstruments pll chip, NTSC and PAL.
I looked up this tuner from your previous mail and 69 is correct. You will note this when it comes to radio, UHF frequencies and takeover frequencies.

Better don't top post. Becomes hard to read after a while.
You would try wsith a gpio_mask = 0x0d.
.gpio for TV is 0x00000000 (default, don't even need to set it).
For s-video and composite 0x08.
For radio 0x04.
On saa7130 chips mono audio from tuner in most cases is connected to LINE2.
Then also radio is on LINE2 and s-video and composite on LINE1.
For .mute it seems to switch to s-video/composite LINE input and keeps that input open with .gpio 0x08.
Maybe Terry knows better.
Good luck for testing.
Cheers,
Hermann
