Hello,
this behaviour also appears on Arch Linux: With Kernel Packages 5.9.x
there was no problem, since 5.10.x I have the same problem with ITE8708
CIR transceiver on NUC7PJYH and ITE8713 CIR transceiver on NUC5CPYB.
I'm using a rc-6 remote.
NUC7PJYH, with broken 5.10.11:
ir-keytable
Found /sys/class/rc/rc0/ with:
Name: ITE8708 CIR transceiver
Driver: ite-cir
Default keymap: rc-rc6-mce
Input device: /dev/input/event5
LIRC device: /dev/lirc0
Supported kernel protocols: lirc rc-5 rc-5-sz jvc sony nec
sanyo mce_kbd rc-6 sharp xmp imon rc-mm
Enabled kernel protocols: lirc nec rc-6
bus: 25, vendor/product: 1283:0000, version: 0x0000
Repeat delay = 500 ms, repeat period = 125 ms
ir-ctl -f
Receive features /dev/lirc0:
- Device can receive raw IR
- Can report decoded scancodes and protocol
- Resolution 8 microseconds
- Set receive carrier
- Receiving timeout 1180480 microseconds
- Can set receiving timeout min 1180480 microseconds, max 1250000
microseconds
Send features /dev/lirc0:
- Device can send raw IR
- IR scancode encoder
- Set carrier
- Set duty cycle

With Kernel 5.9.14 the timing is different and everything works fine
(here for NUC5CPYB):
ir-ctl -f

- Device can receive raw IR
