PS: The RPi 4 has two HDMI outputs. To my knowledge, you can use one for TV (HDMI-0), and one for receiver audio (HDMI-1).

I think the RPi gets audio capabilities from the TV, not from the receiver. Because the TV has no subwoofer, this makes sense to me.

So the routing should be: RPi -- HDMI --> receiver -- HDMI --> TV.

The current theory of our internal discussion is that your splitter does something bad to the HDMI signal. Please try again without using the splitter.

This is the critical part of the log:

Yeah, we should dig a little deeper then. Keep audio settings at pass-through / 5.1 output channels, because this seems to fit best.

1. activate debug logging at GUI (HUD overlay will appear)
2. reboot
3. reproduce the error (audio playback)
4. login by SSH
5. run pastekodi
6. post the resulting link

Please also test pass-through on and 5.1 output channels.

So the result of aplay -L is empty?

PS: It's "amixer", but mixer functionality is what you want, not what you have.

Reddirt You have to find the card name first, see post #28. Then put that name into asound.conf.

Please do two tests:

- switch pass-through off

- set the amount of output channels to 5.1

I've been tested the UMC22 with LE 9.2.8 @ RPi 3B+. It's working fine, so it will also work for you. Highly recommended.

Linux drivers for x86 and ARM (RPi) are different.

There is no HCL.

I can test my Behringer UMC22 on RPI, which is an "ASIO 4 All" (default ASIO) device. Stay tuned.

Then it's a driver issue on both devices. Linux driver support is incomplete. It seems like both systems have trouble to create a virtual mixer device, which controls the volume. Probably LE loads the same drivers, but doesn't accept main audio without such mixer.

Because drivers are part of the Linux kernel, we can't do anything. If you have another audio interface (default ASIO), try it. Or buy a HiFiBerry DAC. They are supported by LE.

Thanks. We will discuss that issue among the dev's.

Do you use RPi OS on the working device?

Can you name the used audio driver(s) of the working device?

LE provides the default ASIO driver, but it seems like your audio interface is using a custom ASIO driver from Digidesign.

Which hardware do you use?

In case you are using config files like remote.xml, then please post them.

Use the linked thread to ask questions. AmandaB was active during the last days, so I guess you can PM her.

OK, thanks for testing.

Disable Bluetooth on LE's settings, reboot and try again. (I don't think that it works, it's just to finish that approach)

My next theory is that Blaze TV tries to use volume control or mixing functions. That's not available for Chrome by default. To add those features, use this thread: Click!

The log is fine, and the error is visible:

It seems like your wireless keyboard is wrongly detected as sound output device (logitech-djreceiver), which kills the default audio. Try with wired input devices to avoid this.
