then reboot and after reboot please show us output of:
aplay -l
dmesg
and
sudo vcdbg log msg
Downgrading to previous kernel it is not final solution, because you can not upgrade in the future. (after upgrade you will recieve new kernel again)
Unfortunately I have not actually any hifiberry card to test in libreelec, but I hope, that if somebody with hifiberry install libreelec, we can check if there is working and which packages is installed there.
In Libreelec forum I can´t find any logs about hifiberry and latest version 9.2 Beta 2
Thanks

Hi
I´m not sure about these logs. For me looks like new kernel has problem with reading of firmware from HAT EEPROM:
[ 4.541850] snd-rpi-wm8804 soc:sound: ASoC: CODEC DAI wm8804-spdif not registered - will retry

In system journal log from kernel 4.14 where is working it is writen:
osmc kernel: snd-hifiberry-digi soc:sound: wm8804-spdif <-> 3f203000.i2s mapping ok
in system journal log from kernel 4.19 is written:
osmc kernel: snd-rpi-wm8804 soc:sound: wm8804-spdif <-> 3f203000.i2s mapping ok
Maybe @sam_nazarko can explain it better - some different libraries?
@tiroy could you please post complete debug logs from kernel version 4.19? (System>System>Logging>Enable debug logging), reboot, and send full logs
Hi @tiroy
I have just one last idea. Could you please try uninstall package alsa-utils ?
It seems,that in version of kernel 4.14 was not this package. Maybe it blocked correct output.
I´m not sure correct command
sudo apt-get remove alsa-utils
This I hope keep setting data for install again if not help.
and reboot
Hi,
I’ve th same problem. I’ve tried everything you all had proposed unfruitfully.
Now I’m trying to roll back to 14.4 kernel but it is not available at all.
osmc@osmc:/lib/modules$ sudo apt-get install --reinstall rbp2-image-4.14.78-4-osmc
Reading package lists… Done

Reading state information… Done
E: Unable to locate package rbp2-image-4.14.78-4-osmc

They are stored in /var/cache/apt/archives but if you cleared the cache you will have to probably have to install the previous build from scratch as it has been removed from the repo.
If you had that package installed still the command that seems to be working for downgrading is…
My knowledge of Linux is fairly limited and that would be outside of my current knowledge. If I owned this hardware myself I think my first course of action would be to get ahold of the people who make this board and see if they can assist with getting it to work with the new kernel.
Barring that I would probably just use the backup feature in the logs section of the MyOSMC app (making sure it is saved to external storage and not the SD card) and install the previous version clean with the OSMC installer (it lets you select which version to install) and then restore Kodi with the backup I made. I would then just stop updating until someone figures out how to get it going and posts instructions.
What does dpkg -l "rbp2-image*" | grep ^ii show? It might be that the 4.14 kernel is still installed, even if the installation file has been erased from the cache.
It took me just a few minutes to do it
Newest libreelec supports hifiberry overlay without any issues.
Here’s the dmesg and kodi.log http://paste.osmc.tv/raw/itixoxakum
