Hi,

I'm sure I have tried that and it didn't seem to work but I'm going to do a fresh install of Pi OS Trixie and Hudiy and will try that again. If it doesn't is screen orientation both for hdmi outputs and touch input OS level or driver specific?

Hi all,

I've googled this and tired multiple ways but just lost on how to adjust the orientation on my hdmi waveshare screen!

I'm running Pi OS Trixie on my Pi4 8gb with CarPiHat.

- My screen has USB-C power direct from HAT 5v output...
- USB-C to USB-A touch input
- HDMI video.

The screen ...

I use the CarPiHAT Pro 5 with built in DAC for both audio out and shutdown and peripheral connections, then use a shutdown script as a service on the pi (already written and provided by the HAT developers) to control boot up and shutdown.

I used to use an sd card but these get corrupted very easily ...

Yes I saw that and had plugged my mic though the DAC still wasn't producing sound which is when I made the changed previously mentioned and now it seems to work.

Ironically this was an easier/ more straight forward solution compared to my similar issues when I was running 1.2 on Bookworm.

So after a bit of playing around and going back and forth... I found a solution which seems to work through reboots...

I edited the boot/firmware/config.txt file and added the following under {all} section at the bottom:

dtparam=audio=off
dtparam=i2s=on
dtoverlay=vc4-kms-v3d,noaudio
dtoverlay ...

and these are my qpwgraph

So this is my Pactl List Sink output

Hi,

I hade been using my setup fine after some changes and bugs on bookworm.

RPi 4 (8gb)
CarPiHAT Pro (power management and DAC)
SSD
Carplay dongle
Waveshare 9.3" screen (usb touch screen and hdmi video signal)
USB Microphone

Though after change my setup and upgrading to Trixie I can't seem to ...

Thank you for getting back to me and confirming my query, just these little aspects are good to know

@Hudiy

I had to do a fresh install as per original method but just wondered, does it install V1.2? Or will it always install V1 and would need to use the built in update script for each new version including the latest one being V1.2?

Thanks,

Sam
