I have used most of the HiFi berry products all of them work well. long time back I had got a clones of DIGI pro from aliexpress, unfortunately didn't work.

Hi All

To update, I had to reset the UEFI, bluetooth keyboard now pairs and connects but it has to be very near to the pc Le. every time the pc Le reboots it has to be paired again any solution on for this ?

the antenna has to be extended from the M2 NGFF WIFI/BT module so that the distance will work, have to think of coaxial wiring as for antennas.

Hi All

on my intel hardware and Le 9.2.4, I am trying to pair with Logitech K380 bluetooth keyboard, I have enabled bluetooth in libreelec settings. when the keyboard is in pairing mode I can see the bluetooth keyboard in the Le menu, when I try to connect it doesn't connect saying timeout I have tried many times its just refuses to connect and pair. I would appreciate help and solution.

For 2ch/stereo keep passthrough disabled.

Passthrough is only needed if you connect a DTS/AC3 capable multichannel receiver via S/PDIF and want to be able to play back DTS/AC3 5.1.

so long,

Hias

HiassofT Thank you..

Hi All,

As the subject says, for LE 2 channel stereo listening, should the audio pass-through be disabled or enabled ?

is it just enough to select the audio device for the dac or USB spdif to send the signal ?

Basically yes, although some network configuration will always be unique, such as IP and MAC addresses, and SSH keys.

How often are you planning to "update" a Raspberry Pi? If you are referring to Kodi's video and/or music library, the use of a centralized MySQL/MariaDB would be a much better solution.

That is often not a very good idea, at Linux likes to tell the different disks apart. Having identical disk labels could confuse the Linux OS or Kodi.

I was referring to library updates.

Switching hdd power on and off is by far what most stress imposes to the electronics and mechanics.

If your hdds are rarely used then you could also take a look at hdd-idle available in the system-tools add-on.

librero there is no frequent switch on or off of hdd's, when I want to use a particular drive, I want to switch it on before the boot of Le.

I will also take a look at hdd-idle

Hello All.

As the subject says, is it possible if I have identical raspberry pi's external hdd's and sd card 's, from backup file of one of the units of raspberry pi can the other raspberry pi be restored.

for example, I have 5 raspberry pi's, I would like to update just one Pi then backup the file and restore it on other raspberry pi's.

Hardware configuration, Pi 3B+, 16gig strontium sd card, 3Tb external HDD.

All the external hdd's are labeled the same.

There are some audio/video sync hiccups, but I don't know if those are the ones in the short 1-2 min video, if those are part of the fastforwarding.

Are you also sure that the video itself isn't the problem?

Klojum they are full length 1080p mkv or mp4 x264 movies, it happens while fast forwarding or skip, using right arrow key.

Klojum apologies to bump, any solution from my logs

You talk about HDMI 5.1 audio. This doesn't exist, but now I have the idea that you eventually use an HDMI audio extractor with an 5.1 / 2.1 channel switch. Am I correct? A user at this thread currently has trouble with such an extractor.

If yes, then your described sound expansion board could work.

I have used the below product for both raspberry and intel/amd as source, and tv/projector as display, with custom made class d amplifiers. only problem is if you don't have multichannel HDMI preamp control, we need to depend on the keyboard volume control, which I found to be little garbage sound.

this co is oem for some good extractors cyp

Yeah... LibreELEC is not a server application, so spinning down hard drives is not a major feature.

But hdparm should do something. Perhaps also search the forum for other hdparm settings/experiences.

Klojum sure will check on "hdparm", alternatively need to design a on/off switch or buy a switch like below link

Quote from Klojum

Oh... So your PC is also your NAS ?

You could try fiddling with 'hdparm' in LibreELEC's startup file,

Klojum My pc is just for LibreElec box, with 6 sata hard drives. when I am using any one particular drive, I would like to power-off the remaining 5 hard drives. all my six drives have audio and video content. the LibreElec boots from a M2 nvme disk. the box is always on 24X7 just a weekly shutdown during night.

Quote from Klojum

I'm guessing that drives in LibreELEC are only unmounted and not powered down. A power led on the external drive should tell you that.

Klojum, unfortunately all my drives are internal SATA, I do not have any external drive for testing.

Quote from Klojum

Removing drives without doing it 'safely' is basically okay for your media drives, because no data is written to them.

Only when you write stuff to the drives (in case of a library export, or subtitles) you'll need to be more careful.

Klojum, what I would like to know is, when safely removed, is the sata power cut off to that particular hard drive ? how to re-mount without reboot

Tx

Hello all

In my intel/nvidia based LibreElec system I have 6 hard disks, when I am watching content from particular drive, I remove other drives by context menu safely remove drives.

my question is if I remove them by above method, is the power and data cut of to the particular hard disk and how do I mount them back without reboot.

Is that true?

If not, can anyone recommend a good usb->spdif device that works, as from Libreelec 9.2.4?

Most of the USB to SPDIF converters work well, I have used dozens of converters none of them gave me any kind of problem.currently I am using MATRIX usb spdif. choose XMOS based chip.

Thanks to Klojum  mglae for the pointers towards the dual boot, today I successfully dual booted to both Ubuntu and LibreElec.

For the benefit of beginners to dual boot LibreElec & ubuntu I am posting the steps involved.( should work with another Linux Distro)

as said earlier the hardware is UEFI.

Dual boot LibreElec & Ubuntu 18.04

first partition the SSD as below

sda1 512mb /boot/efi (EFI partition)

sda2 100gb / (Root Partition Ubuntu)

swap area twice of ram (optional)

sda3 512mb LE_SYS (System partition for Le)

sda4 100gb LE_DAT (Storage partition for Le)

install Ubuntu to sda2 / partition

install Ubuntu boot-loader to sda ( the ssd drive not the partition)

boot to Ubuntu

mount sda3 LE_SYS partition and copy LibreElec's Kernel and System files to the partition, keep it mounted till grub2 update

while in Ubuntu

create the below grub custom cfg file

sudo nano /boot/grub/custom.cfg

add the following lines to the file and close

====================================

menuentry "LibreELEC" {

search --set=root --label LE_SYS

linux /KERNEL boot=LABEL=LE_SYS disk=LABEL=LE_DAT quiet tty

}

=======================================================

after above steps do the below

sudo update-grub2

reboot the system, after bios menu pres ESC to Ubuntu Boot-loader menu there you will find Ubuntu and LibreELEC

select either of OS.

To make LE boot as default OS then edit the below file

sudo nano /etc/default/grub.cfg

GRUB_DEFAULT=3 or "LibreELEC" (the no corresponding to os starts from 0 or name of os in quotes "LibreELEC")

save & close the file,then,

Sudo update-grub

when you reboot LE will boot directly

while reboot if you hit ESC you will get boot-loader menu, where you can choose between the different OS.

Menu will appear if you press and hold Shift during loading Grub, if you boot using BIOS. When your system boots using UEFI, press Esc.

=======================================================
