cec-client fails to swtich HDMI inputs on raspbian

B0GDAN opened this issue · comments

It appears that the cec-client has a serious bug on Raspbian GNU/Linux 11 (bullseye)

echo 'tx 4F:82:10:00' | cec-client -s -d 1
opening a connection to the CEC adapter...
ERROR: [ 4266] CLinuxCECAdapterCommunication::Write - ioctl CEC_TRANSMIT failed - tx_status=00 errno=22

Worked flawlessly on the previous version of raspbian. Any ideas, workarounds?

Thanks
Bogdan

Post output of:
vcgencmd version

and contents of config.txt.
Does it work if you change dtoverlay=vc4-kms-v3d to dtoverlay=vc4-fkms-v3d in config.txt (and reboot).

I will try your recommendation regarding dtoverlay

It works again ;) Thanks a lot!

commented

Anyone know WHY this is happening?

commented

I tested and it occurs with -d 1.
It didn't appear to occur with other values. e.g. -d 2.
Is that the same for others?

echo 'on 0.0.0.0' | cec-client -s -d 1

Segmentation fault

It takes quite a long time and ends with an error, but it works

So a fix or code update is still pending?

Had the same issues until I found this thread. The change suggested work flawlessly.. Thank you Popcornmix!

Using 'fkms' did help, I discovered that right after I asked about the status of this issue. As for the version, it was the older kernel and current Pi OS 11 at the time I asked. the OS has moved on since, but have not used CEC much lately, since I have started using IP based control on devices that support it. However, I still have a couple of TVs that are older and don't have IP control but have CEC is I can re-test. BUT... the question still STANDS... is there not going to be a fix? Using 'fkms' is NOTHING but a temporary fix, work-around, a segmentation fault SHOULD be eliminated, that is the real issue.

I still get that error: tx 1f:82:11:00
ERROR: [ 13518] CLinuxCECAdapterCommunication::Write - ioctl CEC_TRANSMIT failed - tx_status=00 errno=22
other than tx commands seem to work
