IR emitters on HP Spectre x360

[03l54rd1n3]

On my HP Spectre x360 the IR emitters don't turn on when using Howdy on Manjaro KDE. The video feed when testing howdy is grayscale (so I guess it's in IR mode?) and it does indeed draw a red circle around my face. The only thing not coming on are the two red lights next to the camera lens.

There is only one camera I could use:

~ > lsusb            
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bluetooth wireless interface
Bus 001 Device 002: ID 064e:3401 Suyin Corp. HP TrueVision FHD RGB-IR
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I searched the available options and also tried all of them through with v4l2-ctl. None has an effect on the IR emitters:

~ > v4l2-ctl -l -d /dev/video0

exposure_auto_priority 0x009a0903 (bool)   : default=0 value=1

According to some posts I found that the IR camera should be at /dev/video2. I only have 0 & 1 which seems to be the root cause of my problem IMO. Any help would be appreciated to find the cause of my problem. Thank you :)

It's quite common to only have a video0 and video1, my system has the same. As for emitters #261 might help you

So I need to debug and dump my usb communication? Gonna be honest here, that's tough, and for me probably a show stopper.

I know that's difficult, and for almost all users it's too technical. There's simply no easy fix for this

Hello, go have a look on my repo : https://github.com/EmixamPP/linux-enable-ir-emitter. I think you will find your answer, there everything is explained. I remain available if you need help :smiley:

Thank you so much! I will try that but it could actually be that I don't have time for this in the next few weeks. Ich will update here and in your config.txt when I get it (and a darn Windows VM) running.

I will close this issue.
