For debugging, tried another card with similar chips: Pinnacle PCTV 40i/50i/110i. It has SAA7131E chip too, but different tuner - TDA8275A. And the radio problem is the same as found first on the A706 - the tuned station sound starts but then turns into noise. So it seems that the problem is not in tda18271 but in tda8290 or saa7134. With tda8290.debug=1, I see this: tda829x 2-004b: tda8290 not locked, no signal? tda829x 2-004b: tda8290 not locked, no signal? tda829x 2-004b: tda8290 not locked, no signal? tda829x 2-004b: adjust gain, step 1. Agc: 193, ADC stat: 255, lock: 0 tda829x 2-004b: adjust gain, step 2. Agc: 255, lock: 0 tda829x 2-004b: adjust gain, step 3. Agc: 173 During that, the sound is good. Then it turns into noise. When I increased the number of lock detections in tda8290_set_params() from 3 to (e.g.) 10, it works longer. And when I'm quick enough to stop the console output using scroll lock, the radio remains working. > And what's worst, connecting analog TV antenna (cable TV) affects the radio > tuner!

I've found a tiny chip marked S79 near the analog tuner. It's Skyworks AS179-92LF antenna switch that switches either the TV or FM antenna to the TDA18271 FM_IN pin! That's why TV antenna affected the radio. The switch is probably controlled by some other GPIO pin (haven't tested this yet). What's the best way to expose this switch to userspace?

Pinnacle radio problems turned out to be a different bug - the driver turns off tuners when the radio device is closed - and I was testing using v4l2-ctl. Fixing that allows Pinnacle to work fine. But it's not enough for A706 to work. When I disable gain adjust in tda8290 (by putting a return before), strong stations work somehow (with noise). > > And what's worst, connecting analog TV antenna (cable TV) affects the > > radio tuner!

This switch is controlled by GPIO12 (use TV antenna for radio) and GPIO13 (use FM antenna for radio). However, both these pins are tri-stated in Windows - voltage is about 2.2V then, enabling both antennas.

Changing IF frequency from 1.25MHz (1250) to 5.5MHz (5500) in tda18271-maps.c allows the radio to work without disabling gain adjust. Seems that IF mismatch between tda18271 and saa7134 is causing problems. However, only strong stations work.

Got it finally! With .if_freq=5500 and .fm_rfn=0, the radio works perfectly. Now only to find a way how to set a custom std_map...
