Okay, I've tried all hex values from 0x00 to 0x34 for cx25840 audiofmt=X. Some of them, like 0x04 seem to produce badly clipped analog audio, with a lot of static and possibly sampling noise. This is similar to what happens when audiofmt is not specified and the card 'auto-detects' A2-BG audio. Some values produce just loud static noise, some produce clicking noises, other produce quiet static. Certain values 0x10, 0x20, 0x30, 0x40 produce no discernable audio at all, making me suspect it may be just a 4-bit field. None of the values I tried produced clear audio, either mono analog or stereo. Since the tuner is 'multi-standard', is there any way to even set PAL B/G as opposed to D/K? Or is it supposed to be automatic? Is there any way I can find out what the register settings/writes are in Windows? I haven;t tried Windows yet but I suspect it will probably work okay, given the experience of others.
