Lirc stopps working when hyperion is on

Hey volks,

I am not sure if this is a hardware or software issue...so maybe we have to shift this thread to the software forum. But here first of all I my issue

I was running a hyperion setup as follows:

• Raspberry pi 3+
  

  
  

• WS2801 LEDs
• Fushicai UTV007 grabber

Since end of last year I grabbed the picture directly from the scart source of my Sky receiver.

With this setup I controlled Hyperion on/off, USB Grabber on/off and some of the Hyperion effects with my Sky remote via LIRC.

Now I have a new Sky receiver which only has HDMI out. Hence, I had to change my setup by adding

• Splitter
• D/A Convetrer

However, I was not very happy with this setup due to color issue which I was not able to calibrate.

LIRC was working with this setup.

Then I change to a new grabber:

• UTVF007 HDMI to USB grabber

which replaced the D/A Converter an the Fushicai UTV007 grabber.

With this setup I got very good colors etc.

However, LIRC stopped working as soon as I turn on Hyperion (no matter which version 1 or 2ng).
I used

sudo /etc/init.d/lirc stop
mode2 -d /dev/lirc0

to check if IR signals are receiver. Fail.

The command

irw

does not show the keys I am pressing.

Next I replaced the splitter and grabber by a MIRA BOX equivalent.

With this setup

sudo /etc/init.d/lirc stop
mode2 -d /dev/lirc0

IR signals are received.

However,

irw

does not show the keys I am pressing.
Hence,

irexec

does not work to control Hyperion.

P.s. as soon as I turn off Hyperion, LIRC works like a charm.

I already discussed this issue on the German Talk. However, we did not find a solution yet.

TPmodding mentioned that this issue was discussed here in the English thread, however I was not able to find it.

Could anyone please help?

Thanks for your help.
I tried both

dtparam=audio=off


and


#dtparam=audio=off

However, no change. irw and irexec do not work.
mode2 -d /dev/lirc0 works and shows that IR signals are received.

I finally found a workaround to control my hyperion via my TV IR remote: Flirc USB, which can work like a Keyboard. Then I defined some shortcuts via bashrc.

Works!
