Hello,
I did successfully install the latest beta “gta4xlwifi” on my Samsung Galaxy Tab S6 Lite.
After some hour of testing most is pretty working stable except the audio 
The build in speakers and headphone jack do not output any audio - I tried an external bluetooth speaker and the usb-c with headphones connected - this worked.
Does anyone has any experience with this?
Kind regards,
Ronald

I installed lineage-18.1-20211215-nightly-gta4xlwifi yesterday and audio did function so it seems it a bug.
When will be a new version of /e/ released for the S6 lite?
Which /e/ version do you have installed?
I’m on 0.18 and it workst just fine with speakers and bluetooth audio as well.
I’ d used e-0.18-r-20211017141319-dev-gta4xlwifi.zip
Weird. Have you performed the factory reset through eRecovery as stated in the manual?
I did follow the instructions from here:
https://doc.e.foundation/devices/gta4xlwifi
I installed it again but have still the audio issues. Possibly I try to build a e ROM with a newer version of /e/
Finally I was able to build an Unofficial e build using v0.20-r for my Samsung S6 Lite. With using the latest linage custom recovery for gta4xlwifi I was able to sideload and it worked - audio is back again!
I have the same audio issue (Samsung Tab S5e wifi). Im not that advanced to understand , let alone “build” anything to solve it. @ronnz98 how did you do it and would it work for my tablet too? Thank you.
Edit: screen rotation also not working
I have the S5e LTE without having any audio issues nor screen rotation problems so far.
For this device there are current eOS Build for Android 10 / 11 and 12:
I did install 1.6 S but no sound/rotating screen. I have downloaded 1.5 S and 1.6 R and will try them
Maybe it results or of downgrading from A13.
Oh I never downgraded an Android version.
Lineageos just released an an A13 version, might worth a try until Android 13 is supported by eOS:

I have also 1.6S currently installed on my S5e LTE
Thats what I had (the A13 version) 
Anyhow, I´ve sent you an email to stop flooding this topic but will post when I hopefully resolve the sound/rotation issue. Thanks for your answer so far.
You cannot, in general, use /e/OS as a method to downgrade Android OS version. There is an explanation in this post Can I downgrade Xperia tablet Z2 Castor from LOS 18.1 to /e/ q? - #8 by piero.
I didn´t explain that correctly I guess. I wiped everything ,flashed LOS 19 and then /e/os.
However, I now started from scratch:
First downloaded latest Samsung FW, pre-rooted latest TWRP with Magisk (patched), Factory reset and clean install LOS 19, then clean instal /e/os 1.6
Voila! Everything works fine ( no audio or rotation issues anymore)
However, I tried to make an immediate nandroid backup with TWRP and ran into "createtarFork error 255 problem. After reviewing recovery.log it seems that some folders (i.e. data/misc _de) are still encrypted even though I didnt activate any password/pin . Set up a pin, reboot into recovery but TWRP doesnt ask for the pin.
I will reflash recovery and hope this will solve the exncrypt/decrypt issue
