Hi, Léo,

Nice to hear that :-)

Which remote are you using? Do the problems happen with the one that
came with the laptop integrated IR receiver? If the pulse train
frequency of the remote and the receiver aren't exactly the same there
could be problems. A delay could be normal, too.

How did you get the lircd.conf? One for the Acer remote included for
my laptop is in CVS, in the remotes/acer directory. Is it a raw-mode
or a decoded-mode configuration file?

I would suggest starting xmode2 with a suitable -t value (you'll have
to stop the lircd daemon so that the device is free for xmode2) so
that you can check visually if the received signal is consistent.

> I have the original Creative CD-rom driver with the receiver installed in another computer (an old one without linux :( ) and tried the remote control on it and it seems to work normally.

There you're matching remote and receiver.

> Those diffucults could be due to the module or it is an feature of the receiver or the computer? I don't know, have the chip something like sensitivity or signal to noise ratio that module could control?...

I don't know whether there is any configurable reception parameter in
the hardware. At least the Vista driver doesn't seem to support
configuring any of these. Given that there's no datasheet available
for it, I wouldn't count on getting those settings to work even if
they existed. I'd suggest testing first with the provided matching
remote.


Best regards,
