I have an odd problem that the irblaster won't work when mythfrontend or mythtv-setup are active. If neither of those GUIs are operational I can change channels fine with /etc/irblaster/channel_change.sh. Mythbackend can change channels fine as well (again as long as mythfrontend isn't up.)

I fired up the irblasterd in the foreground to get errors, and I get the following when a myth GUI is active and I attempt to change a channel:

and irblasterd dies.

restart with mythfrontend active gives the following output:

restart without mythfrontend active works:


lsof shows nothing grabbing /dev/irblaster[d] by mythfrontend

Note that I do not have a lirc remote for controlling myth, I just have a learning remote that memorized the IR commands from my IR keyboard and control myth that way. I mention that since I'm wondering if the GUIs are trying to get a lirc connection of some sort, and since there isn't one for remotes it grabs the irblaster lirc. Seems far fetched but the only thing I can think of.

I couldn't seem to find any settings related to lirc or items related to serial ports in the myth setup screens.

Any ideas on how to get mythfrontend to leave irblasterd alone?

Check the setup of the lirc daemon (I think you need to look in /etc/lirc/hardware.conf or something like that) and check that it is not using the serial module. Only one of the daemons can use lirc_serial. Most people would be using the lirc_i2c module (or whatever the pvr-x50 cards use) for lirc and lirc_serial for irblasterd.

If you have a serial receiver and transmitter on the same port, you need to use lircd to control both or irblasterd to control both.

I didn't see anything regarding lirc_serial in /etc/lirc/hardware

It seemed both lirc and lirc_serial were using major device 61. I guessed that might be a conflict. I made attempts to get lirc_serial to use major device 72 (like the blaster howto at losdos.dyndns.org) instead with no success.

I eventually built my own lirc as I usually do with the instructions at http://losdos.dyndns.org:8080/public/my ... _LIRC.html except with lirc 0.8.0 and it's working fine now.

Thanks anyway!
