[Pkg-lirc-maint] Bug#790969: lircd stopped recognizing codes

[Torsten Crass]

Package: lirc
Version: 0.9.0~pre1-1.2
Severity: normal

Dear Maintainer,

I am using a home-brew serial receiver in conjunction with an All In One 
URC 7730 remote control in DVD mode with preset 0695 for our HTPC. This 
setup has served me well for almost 10 years, but since a couple of 
weeks or so (unfortunately, I can't figure out since how long exactly), 
lircd obviously has trouble recognizing the keys pressed on the remote.

mode2 still shows nice pulses and spaces, and so does xmode2, but irw 
rarely ever outputs a recognized key press. (The system journal, 
however, shows frequent "Ignoring spike" messages. Don't recall if I've 
had those before, though.)

I also tried to re-create the lircd.conf file using irrecord, but this 
failed for various reasons:
- A lircd.conf created when forcing irrecord into raw mode doesn't lead 
to any recognized key presses.
- When not in raw mode, irrecord detects the remote to use either the 
RC-5 or RC-6 protocol. In the former case, each attemt to record a key 
press results in a "Something went wrong" message, while in the latter 
case irrecord exits complaining about not having detected a toggle bit mask.

Frankly, I don't know for sure if this is a lirc problem since according 
to the change log there were no changes in the lirc package since 
January. To me it seems more likely that the trouble was introduces by 
some other package (possibly used by lircd) when I did a system upgrade 
(which I usually do about once a month). But since I don't have a clue 
which package this might be, I am reporting this to the lirc bug tracker.

Best regards --

     Torsten
