Note: "modinfo <module>" prints various informations about a kernelmodule, among them a complete and up-to-date list of insmod options.This list tends to be outdated because it is updated manually ...==========================================================================bttv.o	the bt848/878 (grabber chip) driver	insmod args:		card=n		card type, see CARDLIST for a list.		tuner=n		tuner type, see CARDLIST for a list.		radio=0/1	card supports radio		pll=0/1/2	pll settings			0: don't use PLL			1: 28 MHz crystal installed			2: 35 MHz crystal installed		triton1=0/1     for Triton1 (+others) compatibility		vsfx=0/1	yet another chipset bug compatibility bit				see README.quirks for details on these two.		bigendian=n	Set the endianness of the gfx framebuffer.				Default is native endian.		fieldnr=0/1	Count fields.  Some TV descrambling software				needs this, for others it only generates				50 useless IRQs/sec.  default is 0 (off).		autoload=0/1	autoload helper modules (tuner, audio).				default is 1 (on).		bttv_verbose=0/1/2  verbose level (at insmod time, while				looking at the hardware).  default is 1.		bttv_debug=0/1	debug messages (for capture).				default is 0 (off).		irq_debug=0/1	irq handler debug messages.				default is 0 (off).		gbuffers=2-32	number of capture buffers for mmap'ed capture.				default is 4.		gbufsize=	size of capture buffers. default and				maximum value is 0x208000 (~2MB)		no_overlay=0	Enable overlay on broken hardware.  There				are some chipsets (SIS for example) which				are known to have problems with the PCI DMA				push used by bttv.  bttv will disable overlay				by default on this hardware to avoid crashes.				With this insmod option you can override this.		automute=0/1	Automatically mutes the sound if there is				no TV signal, on by default.  You might try				to disable this if you have bad input signal				quality which leading to unwanted sound				dropouts.		chroma_agc=0/1	AGC of chroma signal, off by default.		adc_crush=0/1	Luminance ADC crush, on by default.		bttv_gpio=0/1		gpiomask=		audioall=		audiomux=				See Sound-FAQ for a detailed description.	remap, card, radio and pll accept up to four comma-separated arguments	(for multiple boards).tuner.o	The tuner driver.  You need this unless you want to use only	with a camera or external tuner ...	insmod args:		debug=1		print some debug info to the syslog		type=n		type of the tuner chip. n as follows:				see CARDLIST for a complete list.		pal=[bdgil]	select PAL variant (used for some tuners				only, important for the audio carrier).tvmixer.o	registers a mixer device for the TV card's volume/bass/treble	controls (requires a i2c audio control chip like the msp3400).	insmod args:		debug=1		print some debug info to the syslog.		devnr=n		allocate device #n (0 == /dev/mixer,				1 = /dev/mixer1, ...), default is to				use the first free one.tvaudio.o	new, experimental module which is supported to provide a single	driver for all simple i2c audio control chips (tda/tea*).	insmod args:		tda8425  = 1	enable/disable the support for the		tda9840  = 1	various chips.		tda9850  = 1	The tea6300 can't be autodetected and is		tda9855  = 1	therefore off by default, if you have		tda9873  = 1	this one on your card (STB uses these)		tda9874a = 1	you have to enable it explicitly.		tea6300  = 0	The two tda985x chips use the same i2c		tea6420  = 1	address and can't be disturgished from		pic16c54 = 1	each other, you might have to disable				the wrong one.		debug = 1	print debug messages	insmod args for tda9874a:		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)					(default is pin 1)		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)					Please read note 3 below!		tda9874a_STD=n		select TV sound standard (0..8):					0 - A2, B/G					1 - A2, M (Korea)					2 - A2, D/K (1)					3 - A2, D/K (2)					4 - A2, D/K (3)					5 - NICAM, I					6 - NICAM, B/G					7 - NICAM, D/K (default)					8 - NICAM, L	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.	Note 2: tda9874h/a and tda9875 (which is supported separately by	tda9875.o) use the same i2c address so both modules should not be	used at the same time.	Note 3: Using tda9874a_AMSEL option depends on your TV card design!		AMSEL=0: auto-mute will switch between NICAM sound			 and the sound on 1st carrier (i.e. FM mono or AM).		AMSEL=1: auto-mute will switch between NICAM sound			 and the analog mono input (MONOIN pin).	If tda9874a decoder on your card has MONOIN pin not connected, then	use only tda9874_AMSEL=0 or don't specify this option at all.	For example:	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 onlymsp3400.o	The driver for the msp34xx sound processor chips. If you have a	stereo card, you probably want to insmod this one.	insmod args:		debug=1/2	print some debug info to the syslog,				2 is more verbose.		simple=1	Use the "short programming" method.  Newer				msp34xx versions support this.  You need this				for dbx stereo.  Default is on if supported by				the chip.		once=1		Don't check the TV-stations Audio mode				every few seconds, but only once after				channel switches.		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This				should improve things for french people, the				carrier autoscan seems to work with FM only...tea6300.o - OBSOLETE (use tvaudio instead)	The driver for the tea6300 fader chip.  If you have a stereo	card and the msp3400.o doesn't work, you might want to try this	one.  This chip is seen on most STB TV/FM cards (usually from	Gateway OEM sold surplus on auction sites).	insmod args:		debug=1		print some debug info to the syslog.tda8425.o - OBSOLETE (use tvaudio instead)	The driver for the tda8425 fader chip.  This driver used to be	part of bttv.c, so if your sound used to work but does not	anymore, try loading this module.	insmod args:		debug=1		print some debug info to the syslog.tda985x.o - OBSOLETE (use tvaudio instead)	The driver for the tda9850/55 audio chips.	insmod args:		debug=1		print some debug info to the syslog.		chip=9850/9855	set the chip type.
