**Da Flex** · HDMI 0 4kp60 - HDMI 1 Sound **Da Flex** March 11, 2021 at 6:09 PM

I go optical from TV to AVR, and never had problems with HDCP. Maybe you have to setup your TV for this.

Audio over HDMI-1 is possible in theory, but a pretty new feature on LE. Better wait a couple of days until LE 10 arrives, then try again.

**Da Flex** · RaspberryPi4 + HifiBerryDAC2Pro **Da Flex** March 11, 2021 at 5:56 PM

I assume I've been read the HiFiBerry doc about LE. I'm wondering why there is no HiFiBerry analog device available.

Notice step 20 of the doc (amixer -c 0 set Digital 80%). Maybe it's just a volume issue.

**Da Flex** · Intel NUC 8i5BEH - HDMI Sound problem **Da Flex** March 10, 2021 at 9:30 PM

Can you check your EFI settings? Maybe your HDMI ports are set to DVI mode, which has no sound. Use HDMI mode instead.

**Da Flex** · Xiaomi Mi Android Box **Da Flex** March 10, 2021 at 9:15 PM

I think it's better not to buy a box with a locked bootloader ( PANiCnz is right). Go for another Intel box (Tiger Lake NUC) or an RPi.

It was a limited offer for a pre-production sample of the ESP32-C3. It's not available anymore. A regular ESP32 is cheap (eBay: ~5€ from Chinese traders). The benefit of a regular ESP32 is that you can program it by the Arduino IDE.

The HiFiBerry is analog.

**Da Flex** · I2S to SPDIF **Da Flex** March 9, 2021 at 8:30 PM

OK. Seems like there is no I2S master clock provided by RPi, resulting in no driver available.

Maybe this thread can help you to generate a master clock signal: Click!

The typical solution is to get a HiFiBerry HAT. Is there any reason to invest that much time for a custom SPDIF?

**Da Flex** · I2S to SPDIF **Da Flex** March 9, 2021 at 7:13 PM

Master clock signal is optional for I2S - not part of the standard.

Ok, I never done something like this. How can it be done ?

Chances are that it's too difficult for you. I'm currently building a music player (MP3 and internet radio), which is very easy to build with an ESP32 micro controller (thanks to lrusak for the tip to get a free ESP32 sample, I had it in the mail now ). So if you just want to play music, there are easier ways. Touchscreen support is available for ESP32. Here is the project for the ESP32 music player: Click!

I've seen a user (I think it was thedogg ), who was able to run LE from USB stick with locked bootloader. Not sure about the box he used.

**Da Flex** · IQaudio Codec Zero **Da Flex** March 8, 2021 at 7:36 PM

The device is made for Pi Zero, so I'm not sure whether it's compatible to RPi4B. Take another microSD, and test with Raspbian. If the device also fails on Raspbian, then I bet it's incompatible hardware.

**Da Flex** · IQaudio Codec Zero **Da Flex** March 8, 2021 at 6:48 PM

It's an I2S device, so activate dtparam=i2s=on at config.txt.

**Da Flex** · Updating LibreElec/Kodi **Da Flex** March 8, 2021 at 6:21 PM

You can find test builds at the Amlogic sub-forum. I'm not familiar with that hardware. Be careful, backup first.

**Da Flex** · Updating LibreElec/Kodi **Da Flex** March 8, 2021 at 5:59 PM

Put the img.gz file into /storage/.update and reboot to start the installation.

**Da Flex** · No Audio over HDMI **Da Flex** March 8, 2021 at 5:55 PM

Make sure dtparam=audio=on isn't commented out at config.txt. Eventually you commented it out to setup your HiFiBerry HAT.

**Da Flex**

Please try with pass-through enabled at the audio settings.

**Da Flex** · IQaudio Codec Zero **Da Flex** March 8, 2021 at 5:34 PM

Sorry, but RTFM. It says you have to comment out dtparam=audio=on at config.txt and reboot.

I connected the raspberry to an hdmi port on the receiver which I am sure it works and my receiver manages all the encodings up to True HD and DTS Ex. But even when the passthrough is turned off, no sound is heard, not even the sounds of the skin.

Audio over RPi HDMI-1 is a pretty new feature, so it could be buggy. Can you try RPi HDMI-0 -> TV -> AVR?
