LibreELEC Nightly RPI2 latest builds fail to boot.

hbbs · September 7, 2023 at 5:04 PM

Hi.

The latest nightly builds (RPi2) from September, 04 onwards are failing to boot properly on my Rpi 3B+.

https://test.libreelec.tv/12.0/RPi/RPi2/

I have already lost my installation. Wiped everything to start anew to no avail.

There is an ongoing problem with the latest builds that are making the booting process loop right after the logo is shown.

Is that a known issue?

Please, let me know.

Just booted my 3B+ with LibreELEC-RPi2.arm-12.0-nightly-20230907-5502dd5, no problems.

At the moment of this writing, I'm low-level formatting my SD card. It will take a while to finish it. In the meantime, I'm gonna buy a new SD Card.

This is strange. My RPi was working normally until I updated from the nightly build of September, 02 to today's build.

Just one more thing. Before the low-level formatting of my SD Card. I flashed the nightly build from September, 02 and it booted normally.

But the builds after that they all are failing to boot. Caught in a loop.

I will be back later today with more information.

Thanks

I believe I found what is happening.

After trying a new SD card and even another power supply I decided to open my Raspberry Pi case to have a look.

Putting everything back together I forgot to reconnect my USB Audio SPDIF dongle and powered on. To my surprise it successfully booted.

When I connected my USB Audio dongle LibreElec crashed and then got stuck on a loop while trying to boot, just like before

This is only happening with the nightly builds after September, 02.

chewitt what changed after Sep,02 that is causing these issues?

Please, let me know

PS: My USB Audio SPDIF dongle is a Turtle Beach Audio Advantage Micro II.

My bet would be on the ALSA update https://github.com/LibreELEC/LibreELEC.tv/pull/8095

But we need logs to be certain:

Add "ssh" to the end of cmdline.txt (on the same line, use eg notepad++ on windows to edit that on the FAT partition), then quickly ssh in after boot, while kodi is in a crash loop and enter "systemctl stop kodi".

Then run "pastecrash" to update the crash log info and post the URL you got - from there we can look further.

so long,

Hias

Hope it helps.

Hmm, unfortunately the interesting bit, the stack backtrace, was missing in the log.

Could check if you have more kodi_crashlog files in /storage/.kodi/temp and upload them, too (eg with "pastebinit

/storage/.kodi/temp/kodi_crashlog_<SOMETIMESTAMP>.log")

According to the log there should also be a /storage/.kodi/temp/kodi_crashlog_20230907190747.log file (there might be more, but older ones will eventually get cleaned up automatically).

so long,

Thanks, kodi_crashlog_20230905155633.log indeed shows that kodi is crashing in the alsa lib, I've informed heitbaum about it.

so long,

I did some looking into this today.

I cant see dmesg for the device (not that that would help me directly.) but good to get all the info.

Here is the code that is being run - just after this (I believe at the time of the crash). debug logs - would be required next. Also what the log would normally say after the last "info <general>: CAESinkALSA - Unable to open device "surround71" for playback"

Thanks for replying.

Just to make clear. Do you want me to provide anything else?

Feel free to ask.

**HiassofT** · September 8, 2023 at 2:40 PM

hbbs thanks, I've managed to reproduce this issue locally now and will investigate it. ATM we don't need anything else from you

so long,

Hias

**HiassofT** · September 8, 2023 at 8:12 PM

hbbs can you please test and report back if this build works?

HiassofT

Yes, it did solve the issue I reported yesterday.

If you excuse me. I'd like to report another thing. This is not new. It is something that appeared late in the last development cycle.

The reason I'm bringing this up is because I extensively tested the SPDIF out capabilities and what I'm about to report just started to happen a lot

Here's what happened on the log that I attached below

I played a movie with an AC3 5.1 audio track. So far. So good.

Now is when the issue begins. I stopped the playback of said movie with an AC3 5.1 audio track and went to play another movie title, but this time with a DTS audio track.

The sound doesn't come up. My audio receiver still shows DD Digital. It got stuck this way when I played the first movie title with an AC3 5.1 track.

In fact. Not even the Kodi GUI sounds are being played.

After that, I went to listen to a Web Radio (Stereo) and no sound came up.

The only way to listen to a sound is by waiting. Sometimes this takes too much time it is better to reboot LibreELEC.

But again eventually my audio receiver dropped the DD Digital to No Input and after that, I got sound again.

I thought since you guys are looking into ALSA maybe I should mention this issue as well

Feel free to contact me if anything is needed.

Regards.

H.

**HiassofT** · September 9, 2023 at 12:32 AM

Thanks for testing, I've PR'ed the workaround/fix https://github.com/LibreELEC/LibreELEC.tv/pull/8126

Concerning your other SPDIF/passthrough issue: please open a separate bug report thread for that and provide a full debug log (using pastekodi or the log file upload function in LE settings)

so long,

Hias

Here it is: SPDIF passthrough mode getting stuck on LibreELEC (no sound) while changing Audio Codecs types.
