And that would be in system settings/audio as well? I´m in expert mode now, but there´s no fader there. Does it make a difference that I´m using my pc to access the configuration via x.x.x.x:8080?

Cheers, but I would still need to somehow configure libreelec to forward the input to the output, right, or you suppose that´s done all by itself once having chosen the right entry? If so, it´s not working - nomatter the chosen output, I only get sounds from libreelec itself.

Thanks, it looks like this:

Thanks, I´ve been reading a bit about pulseaudio and its loopback. Wouldn´t this be the way to go?

Dear all,

I´ve got a hifiberry digi I/O card, from which I want to be able to always hear the incoming audio in libreelec. I had the same question a while ago for a hifiberry DSP card, where it was very easy since this card is by default configured to allow such action. But apparently the digi I/O is not, so I guess it will need to be set up manually.

I assume the question is general aka could be applied to any device attached to the pi either via USB, or as in this case, a hat. Of course you´d need to address the correct device name in the configuration.

FYI, audio from libreelec does go out as it should, so it´s indeed seen by the system - it´s the input that needs to be configured for forwarding its signal through to the output (and not conflict with sound from libreelec, but mix with it).

Any advise?

On LE's audio settings you should see your DAC as new output device after driver activation. Maybe the menu will show multiple DAC output entries (profiles), and you can select a mixing or non-mixing profile.

I don't have this hardware. The HiFiBerry forum can tell you more about those DAC profiles.

Thanks a bunch, now I´ll consider this my personal xmas-gift for 2020

That's good news! So I guess you just have to activate the driver, and the default routing of the driver (not LE) will do the trick.

Add this line to config.txt:

Code

dtoverlay=hifiberry-dacplus

Thanks, so will all the libreelec-sound be mixed with the input, or how does that work?

Ah now I know what you mean... I was confused because you refer to the hifiberry board as "the DAC", with which I thought you meant the DA converter on the board.
I´ll ask on the hifiberry forum then - just not sure about how much KODI-help they are capable of giving, but thanks!

EDIT: Ok, so I got a thumbs up at the hifiberry forum now, telling me that this is "the default profile" of this board to forward from Digital in to Analog out on the board itself. So you think I would not need to configure anything inside of libbreelec to make it work then?

Quote from Da Flex

If you go DAC -> RPi -> DAC, then the RPi will become a bottle neck, because incoming DAC data have to go to RPi's bus controller, and then back to GPIO. I belief that the GPIO itself is another bottle neck, because probably the same pins will be used for input / output.

Even if such a pass-through-over-RPi function exists, it has to be managed by the HiFiBerry driver, not by LE. Again: Ask the HiFiBerry support to get the definite answer. They are friendly and firm. On a regular PC you would be right, and you would get the desired routing options, but an RPi is different.

Maybe I´m just misunderstanding you, but why do you say "DAC -> RPi -> DAC" when the routing is from the hifiberrys digital input to the hifiberrys analog output?

Quote from Da Flex

I think I understand your setup now. You want a pass-through function inside the HiFiBerry DAC. This is not part of LE's audio.

Those DAC's are made for RPi -> DAC and DAC -> RPi, but not DAC -> DAC. Ask the HiFiBerry support to be sure (they are pretty good).

I suggest to use something like this instead (and hope for low latency).

Hi again and thanks for coming back.

What do you mean with that they´re not meant for DAC to DAC (although I´m talking about DD-DA, and not DA-DA)? The mentioned board provide devices to the system, 1 analog in and out, and 1 digital in and out, which under normal circumstances can be set to route the audio as desired. The question is if they can be set up for that within libreelec.

Quote from Da Flex

This is hard to answer, because so much data is missing on your description.

What exactly do you want to do?

What's your hardware (RPi version, HifiBerry version)?

Which input / output ports do you want to use?

Do you want to use a MIDI device connected to the RPi?

If the answer to last question is yes, then LE is not the right OS for you. Instead you'll need a real-time (RT) kernel OS (like Patchbox OS). That will provide low latency MIDI processing.

Thanks Da Flex!

It´s an RPI 4 that I got here, and it´d be this hifiberry board:

HiFiBerry DAC+ DSP | HiFiBerry

I simply want to connect another raspberry, which is already set up with midi keyboard, playing vst´s through reaper, and a hifiberry digi+ board with toslink out, to the libreelec rpi´s hifiberry digital input, and then take the analog signal from the hifiberrys out and put it through my amplifier.

Why? Because the way it is now, where my "DAW-pi" is connected directly to the amps digital input, the latency of the amplifiers DAC is a bit too much - at a latency of just 2.9 ms, I can feel the latency. Setting it to a lower value fixes that, but also starts introducing glitches now and then. Others dont have that problem, and I know that my ears dont hear latency till around 11 ms, hence I conclude that its my 10 year old onkyo amps fault that it´s like that. Hifi-amps arent ment to get you ultralow latency anyway.

And further to this, it´s pretty convenient that I don´t need to switch between the daw-pi and the libreelec-pi on the amp, if I could do as described here.

Dear All,

I was wondering whether if it´s possible to let libreelec forward an incoming audio signal to the output, either mixed with audio playing libreelec (from for instance a movie) or without it.

I´d be using a hifiberry board for everything here, and I´d need to make sure that the system can give me the lowest latency possible from input to output as well, as part of the inputsound is from a midi keyboard. I assume that the latency would be ruined if I use audio through HDMI, so I´d be using a hifiberry with optical in and analog out.

And if this all works, will there be issues with audio and picture out of sync, when watching movies on libreelec, due to audio no longer going via HDMI?

I honestly don't know. Did it break because of what Apple might have done or because of some other regression, directly related or not...? Your added information about Tuneblade (that's new to me) may be pertinent. I don't use Airplay with Kodi - I was simply trying to add some background regarding the way that Apple control Airplay and how that may affect unofficial clients for which the developers have to try to figure out what changes are needed each time that Apple make a change.

Tuneblade was mentioned initially, but thanks for your still vaulable inputs. I´m just thinking that if the only two pieces of code involved here are libreelec on my raspberry and Tuneblade on my pc, then if Tuneblade has not been updated, and libreelec works better with airblade in its older versions, then the culprit is libreelecs airblade implementation that differs between libreelec versions, to please protocol changes launched by apple.

I just tried achieving the same with DLNA btw, where I found a win app called "streamwhatyouhear" but there I get a dropout every two mins or so, using the lossless audio mode. Not sure if it works fine with mp3 compression, which is another option but I want it to be lossless.

I am not aware of version specifics, but it is more likely that this has broken as a result of changes to iOS from Apple (whether iOS 14, 14.1, etc. - who knows...).

But we agree that it´s the airplay implementation within Kodi which is broken because of trying to keep up with that? I mean, at my end I´m using no apple stuff, just Tuneblade which has not been updated since last year.

Thanks guys, so the issues I experience is because that the airplay version used in latest Kodi is different from in older versions, because Kodi developers have been trying to keep up with protocol changes, introducing bugs on some none-apple devices?
In that case, it´d be great if it would be a separate module that can be easily downgraded.

Dear All,

(moved from Airplay got worse after updating to new build of libreelec on rpi4, since I got the feeling that it´s the wrong forum to post this in)

I got a hiccups in my previous installation of libreelec so that it wouldn´t launch any longer, and had to reinstall it.

For this reason, I´m not sure which version I was running before - all I can tell is that it´s now the latest, 9.2.4.

I´ve been using Tuneblade on Windows alot for a long time with no major issues to stream audio to airplay on the pi with libreelec, but after the new installation of libreelec, I get a lot of glitches in the audio within minutes, and then the connection dies.

I don´t know if it´s airplay itself that´s the problem, or some power saving thing or network limitation set in the new installation that is causing it, but it´s very frustrating.

Anyway, I decided to try with a downgrade to 9.2.0 and guess what: Everything works really great again. I´d be really happy if somebody could figure out what´s wrong with the more recent versions, so that I can safely update libreelec again.

The downgrade was done after that libreelec had autoupdated itself to latest version when installing a fresh 9.2.0, which had the issues mentioned, and then with 9.2.0 in the .update folder. Just to avoid any speculations here about if I´d tweaked some settings that made things go smooth in 9.2.0 - everything´s the same whether if in 9.2.0 or latest build.

Thanks in advance!

Is there a particular log file that I can show you, or do you already have some good ideas about what the problem derives from, and how I could resolve it?
