Hi,

first, sorry for my poor english

No sorry not sure what to do, i've try many configurations and 
modifications in order to have svideo/composite audio but no result

you can try different parameter (see in sources, take example on other 
cards)
or ask on linuxtv mailing list
I forward your precedant mail to this list

Cheers

Thomas

there are different models of the HVR-1110 we can see on
hauppauge_eeprom down in saa7134-cards.c.

Some don't even have analog audio in.

In case it is there, if the current LINE2 stereo input pair doesn't
work, then it is LINE1.

If that still does not work, you can expect an external gpio driven mux
chip on the board. On cards with analog audio out it can be fairly easy
tested by unloading the driver. Default is then to loop the sound
through to the analog output of the card to the soundcard, but with the
driver unloaded you can't test, since you need saa7134-alsa for it
without having analog audio out connected on the card.

In that case regspy.exe from DScaler (deinterlace.sf.net) might help.

A work around could be to plug the external analog sound directly into
the sound card/chip and record from there.

Was the radio ever tested? Since the tda8275ac1 has only one RF signal
input pin and the card has two antenna connectors, we usually see that
these inputs are switched on gpio21 including the AutoGainControl and
using the 5.5MHz ceramic filter for radio input.

See the other cards with TUNER_PHILIPS_TDA8290.

Mostly it is high (0x0200000) for the radio switch, only sometimes the
other way round. Then you must set .gpio = 0x0200000 for the TV input
with the same gpio_mask.

Cheers,
Hermann

For the TV versus radio switch the gpio mask is just 0x0200000.

With this mask only gpio pin 21 will change.

By default the driver will set it to 0, only for that input gpio =
0x0200000 is set in the card's config, it will change it to 1.
(masked writes, "modinfo saa7134" gpio_tracking=1)

If changing the amux to LINE1 doesn't help for s-video and composite,
testing with saa7134-alsa there and say sox, then regspy might help.

If you use the supplied m$ app, not DScaler, and save the logs for the
card in status unused, TV, composite/s-video and radio, we will see the
gpio mask in use there and likely changing gpio pins.

They often have more pins in the mask and also more that change,
but usually one of them will be what we need to add to the mask.

It looks like manufacturers group their devices together with a gpio
mask covering so far all of them, then subsets of devices do appear,
which still do more changes on the pins, then for a specific single
device would be needed.

With a high granularity for each device, based on a doubtless and
consistent eeprom detection, the gpio settings likely could be single
device specific too, if wanted.

But since we might see unrelated gpio changes there too, dunno, first of
all make sure that amux LINE1 does not resolve the problem.

Cheers,
Hermann

I remember that regspy shows nothing when i attempted to switch to 
svideo/composite.
i haven't got a pc with windows (only linux + freevo on it) so i can't 
do anything else for now.

Line1 doesn't work for me so it's why there is a FIXME in sources ....

Cheers,

Thomas.

You can try here :
http://sourceforge.net/project/downloading.php?groupname=deinterlace&filename=DScaler4115.exe&use_mirror=heanet

regspy is included in DScaler

Post your log here
