Intel published a whitepaper about USB3 / 2.4GHz WIFI interference some 9 years ago: USB 3.0* Radio Frequency Interference on 2.4 GHz Devices

Interesting read and it includes some hints what you can do to avoid / reduce the issues.

Could you please give this test build a try? LibreELEC-RPi4.arm-9.80-devel-20210124165749-4b10646.tar

It includes a couple of patches to trying to fix issues we've seen (audio FIFO overfilling, audio buffer underrun in kodi) and also includes a patch to periodically check for HDMI FIFO issues.

If you run into audio dropouts please upload a pastekodi log. BTW: no need to enable audio or video component logging in kodi, that won't reveal anything interesting and just bloats the log.

Remove 4096x2160 from your whitelist - this doesn't work in kodi Kodi switches to incorrect whitelisted resolution · Issue #19037 · xbmc/xbmc · GitHub

Check your TV and whitelist settings. Make sure overscan is disabled on TV and kodi actually used 3840x2160 (not 4096x2160).

As usual, debug logs help.

Current plan is to release official Alphas for RPi4 along with the other Alpha builds.

RPi2/3 releases will probably follow later as there's a major issue in the video driver (screen going blank). Once that's fixed RPi2 alpha builds will follow.

The 4k 24 FPS files I tested with (8 and 10bit HEVC) played fine. Can't say anything about 50/60 FPS as video driver doesn't support 50/60 Hz yet.

so long,

Hias

Quick heads up: the next nightly build adds support for 4k up to 30Hz (60Hz needs more work and will follow later).

It's best to configure display to 1920x1080 60Hz and whitelist 4k 23.98/24/25/30 and 1920x1080 23.98/24/50/59.97/60 modes (plus any other lower res modes you want).

in LE 9.2 you can change repeat settings via a udev rule, eg /storage/.config/udev.rules.d/99-my-repeat.rules with this content:

ACTION=="add", SUBSYSTEM=="input", SUBSYSTEMS=="rc", KERNEL=="event[0-9]*", \
  RUN+="/usr/bin/ir-keytable --delay=750 --period=150 --device=$devnode"

See also /usr/lib/udev/rules.d/70-input-repeat.rules (which applies to non-rc-core devices).

Screen tearing is a known issue with the FKMS driver used in 9.2, it's fixed in LE10 nightly builds which uses the KMS driver that doesn't have that issue.

Try with "guide" instead of "epg" in the keymap.xml file. The "KEY_EPG" code is mapped to the "guide" button in Lircmap.xml (see the devinput section).

I've just sent the fix upstream and created a PR for LE linux (default): add patch to fix ite-cir issues by HiassofT · Pull Request #4908 · LibreELEC/LibreELEC.tv · GitHub

It should be included in nightly builds soon.

truespidy I could reproduce the issue here on a PC with ite-cir, it's another kernel bug

Could you please test with this build: LibreELEC-Generic.x86_64-9.80-devel-20210109151324-492ba03.tar

Thanks for the log, the output looks like the remote buttons were pressed for about 2 seconds.

Stop kodi and eventlircd, then run "ir-keytable", then "ir-keytable -t" and push a button for a short time and post the output.

Hias

Thanks a lot for reporting!

We identified the issue and reverted the breaking change. The next nightly build should be fine again.

Hias

We temporarily had to revert the HD audio changes as they seem to trash filesystems on RPi2 - we'll add them back once that issue is fixed.

So stay on 20210108 for testing ATM.

Quote from truespidy

I tested the devel version from post #33. Unfortunately, this did not solve the problem for me. The current nightly version behaves identically. Each keystroke on the remote is now repeated several times. What commands should I execute to provide a log?

Start with describing your setup (what kind of remote, IR receiver, hardware you are using) and a standard debug log (note: either use the log update function in LE settings or "pastekodi" on the command line).

FYI: all changes have been merged into LibreELEC master and are included in today's nightly build.

Please use nightly builds for further testing.

so long,
