1. remove the second line . $(dirname $0)/incl
2. replace the third line by export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${TVM_ROOT_DIR}/lib
3. find the value of variable TVM_ROOT_DIR by: echo $TVM_ROOT_DIR
4. create the line export TVM_ROOT_DIR=/YOUR_TVM_ROOT_DIR

Result should be like (/YOUR_TVM_ROOT_DIR replaced by the result you found at point 3):

#!/bin/sh

export TVM_ROOT_DIR=/YOUR_TVM_ROOT_DIR
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${TVM_ROOT_DIR}/lib
export TVMOSAIC_ROOT_CONFIG_DIR=${TVM_ROOT_DIR}
${TVM_ROOT_DIR}/tvmosaic_server

Yes, by using a tvservice command line option inside an autostart.sh script. However, I'm sure you want to turn the display on again, but that's a problem. My tests gave me a Kodi error when trying to turn the display on by tvservice command.

Maybe it's just a script challenge to stop and start Kodi at the right time (before and after turning the display off/on). But without Kodi running, there probably must be found a different way to get an event for display wake-up.

Then post the start2.sh script please. When it's a large script, use a link to Pastebin for publishing.

Start another simple shell script (test file creation etc.) from autostart.sh to be sure that shell-script-to-shell-script works.

Cool. Using a smart phone app might be easier than the IR approach. Your choice.

If it has been working before, better HDMI cables might help. Maybe volume change increases data rate, and one or both of your HDMI cables can't handle that data rate. HDMI 2.0 or 2.1 standard cables work fine for RPi 4.

At config.txt you can try hdmi_safe=1 for maximum compatibility among devices.

Other users do RPi -> AVR -> TV without problems, so I think your AVR interrupts HDMI connection. Try RPi -> TV -> AVR instead.

For kicks and grins I created the file and copied it over like I did with advancesettings but I'm not sure I dropped in the right country code as IEEE doesn't have a code for the USA but does for my region (Eastern US), which is a 2. Now I don't see the 5GHz SSID at all.

Country ID's are for countries, not for regions inside countries. That means LE's default country US already fits for you, and there is no need to create that file.

So you're using the right WiFi configuration, but it looks like the WiFi signal isn't strong enough. You have to buy a WiFi adapter with an antenna for your WiFi surrounding, like the one I mentioned above. That will improve signal strength.

I'm running LE 9.2.1. is there such an interface for this version or do I need to create the config and push it over?

You already learned how to use the nano editor, right? If the file doesn't exists, then you have to create it. It's the same procedure like on your advancedsettings.xml problem:

nano /storage/.config/modprobe.d/cfg80211.conf

Then add this line, but replace US by your country ID (IEEE standard):

options cfg80211 ieee80211_regdom=US

Thanks for testing. Remove the (...) &, which makes the call a background process. Make sure both scripts have executable permissions (chmod +x).

Some scripts assume you're already at their folder. So try:

cd /storage/tvmosaic
/usr/bin/sh start2.sh

Or make autostart.sh a link to start2.sh by using ln -s.

It's a known issue that some USB sound cards (DAC's) don't work on RPi's. Fortunately there is an LE audio mod available, which you can try. If you follow that link, you can read my theory about the problem.

chewitt:

The USB WiFi dongle I have been suggested has an RTL8811BU chipset. Can you please confirm that this chipset is supported by LE?

Support here is pretty good, you just do exotic things with your display. What you want is to invert width and height parameters after screen rotation. Because there are no pre-defined HDMI modes for that case, try to define your pixel width and height manually by using hdmi_cvt (chapter "Custom mode").

5GHz is a game changer. Other users have trouble with RPi's internal 5GHz WiFi, too. This should work on RPi's.

If you want to stay away from any driver trouble, get an ethernet-to-wifi adapter. And as you know, antennas are always good for connection.

PS: That thing will do. Benefit: It has an own power supply, which is good for your RPi.

You can use CTRL+S as well these days.

Yeah, key combos everywhere. At least nano shows them on the bottom. That's a new level of editor design I guess.

No, you just have to create the XML file, the rest of the path is already there.

When you plug the card into your PC, search for a partition named STORAGE. This represents the path /storage. Then activate showing hidden files on your PC's file manager. This should make the .kodi folder visible.

There is no way to create the file by UI. You can remove the card, or login by SSH and use the nano editor to create and edit it:

nano /storage/.kodi/userdata/advancedsettings.xml

After writing the content, store the file by key combo Control + O, followed by Enter for confirmation. Then leave by Control + X.
