I have a question, does anyone know a method to start in the Opi Lite system the I2S audio interface and in particular I mean the module: PCM5102 / PCM5102a On my old OrangePi Lite board, sound and audio in the configuration as mentioned above really work great ... but unfortunately the Armbian system that I use is no longer supported. This is the Ubuntu version (xenial) and kernel: 3.4.113-sun8i, I managed to update some programs important to me, e.g. mpd / mpc but not to the latest versions. I also have another version of OrangePI 3 LTS and I know that on this model it is rather impossible to start I2S + PCM5102 so I used a good sound card under USB and it is OK. However, I think that it should be possible on the Pi Lite? so far I have tried such a howto ... but without success. armbian-add-overlay sun8i-h3-I2S-out.dts entry in the file sun8i-h3-I2S-out.dts : /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; fragment@0 { target-path = "/"; __overlay__ { pcm5102a: pcm5102a { #sound-dai-cells = <0>; compatible = "ti,pcm5102a"; pcm510x,format = "i2s"; }; }; }; fragment@1 { target = <&i2s0>; __overlay__ { status = "okay"; pinctrl-0 = <&i2s0_pins>; sound-dai = <&pcm5102a>; pinctrl-names = "default"; }; }; fragment@2 { target-path = "/"; __overlay__ { sound_i2s { compatible = "simple-audio-card"; simple-audio-card,name = "I2S-master"; simple-audio-card,mclk-fs = <256>; simple-audio-card,format = "i2s"; status = "okay"; simple-audio-card,cpu { sound-dai = <&i2s0>; }; simple-audio-card,codec { sound-dai = <&pcm5102a>; }; }; }; }; }; and an additional entry in the armbianEnv.txt file : user_overlays=sun8i-h3-I2S-out I once did it according to another tutorial but it was on the old Ubuntu Xenial system https://www.dimdim.gr/2016/12/orange-pi-one-lite-as-music-streamers-part-2/ It would be useful to update the system and kernel after a dozen or so years 🙂

i2s doesn't work on my OrangePi lite either...oops

I checked again and the latest stable version works correctly with OrangePi3 -LTS also the I2C interface for my 40x2 LCD is version: Armbian_23.11.1_Orangepi3-lts_bookworm_current_6.1.63. https://k-space.ee.armbian.com/archive/orangepi3-lts/archive/ regards

Every rational user knows exactly what it's about... after all, no one will spend their time updating and improving the firmware for every piece of equipment, even if it's only from OrangePi. Unless you're a retiree and have a lot of time and willingness and a sharp mind... oopsss 🙂 Or maybe some other form of help could be used instead of the so-called help from the community (which probably means no one) from the forum? For example, a form of payment for a specialist, developer to adjust or update a specific piece of equipment/model, e.g. OrangePi3-LTS in the form of a progress bar of payments for a given model? ... I wonder if there are people willing to use this form of help... So a proverbial fundraiser for a specific model? Ps. I found a version for OrangePi3-lts with an old, properly working kernel: 15.16.17.7 ... but Debian is already a bookworm https://github.com/silver-alx/sbc/releases

In my opinion, if someone is looking for the orangepi platform as an audio video player, it is better not to use the OrangePi3-LTS version. I searched the internet for some information about this model and I will honestly say that it is tragic 😞 I am currently using the above-mentioned Pi-3-LTS model as an internet radio and I will say that I managed to set almost everything correctly except for the I2S interface, which is why I could not connect the module: PCM5102 (DAC) But you can easily use an audio card under USB and it is OK also as a DAC (32bit). So as an internet radio, the OrangePi3-LTS is OK, if you could run I2S it would be PERFECT.....but this OrangePi model as an audio video player is currently and looking at the internet it is generally a bad solution, it is better to look for something else and preferably a model supported by Armbian developers! 🙂 I use the official OrangePi firmware version for internet radio, not Armbian! because on this old version almost everything works, including the I2C interface for LCD 16x2 / 40x2 Ps. How to configure such a radio I described a bit on the Polish Ubuntu forum ... but this is a tutorial in Polish 🙂 more information LINK LINK2 regards

OK ... but the fact remains that the official version of OrangePi works OK ... and the latest Armbian is nothing but trouble, precisely because there is no longer support from Armbian developers, only from the community on the forum. So I recommend this older firmware from 2022 on OrangePi3 LTS because it works properly. It's great to know that it's still a version of Armbian from years ago 🙂 Ps. I checked I2C with my 40x2 lcd and the kernel probably doesn't work? ...lots of errors on these community Firmware ...

Orange pi 3 LTS is not supported by Armbian developers but only by the forum community ... so do not count on super correct operation of this model and Armbian firmware, it is probably better to use the official FW from OrangePi for now, although the versions are not updated often and the last ones are from 2022. However, they work well, although I do not have high requirements for this model because I use it as an internet radio 🙂

I was looking for information about lirc because I use mpd / mpc / LCD and the mpd / mpc program is controlled by the lircrc file. I think I found a solution for the mce / rc6 remote control because for the radio remote control medion x10 ( or24v / or28v ) selecting driver : atilibusb ... the remote control works OK However, you have to use the ir-keytable program + program : triggerhappy maybe someone will find this information useful. more information: Configuring an Infrared Remote Control to Control mpd/ mpc (without needing LIRC)

Does anyone use an infrared remote control with the Lirc / rc6 / mce program..and have a verified configuration? I can't configure the above to work on Orange pi 3 lts But I want the Lirc program and not the ir-keytable 🙂

I currently have OrangePi3 LTS and I use the firmware provided by OrangePi and there you had to install wiringOP and also run during system startup: i2c0 in the file: orangepiEnv.txt That is, add the entry: overlays= i2c0 i2c1 i2c2 In Armbian firmware it is probably easier, you have to run the configuration from the terminal: armbian-config and there find the section: I2C and enable: i2c0 / system restart then proceed as you previously provided on the forum. How to connect LCD to your model ... probably like I did to my OPi 3-LTS according to this tutorial. Of course the board is different but you have to find the same pins on your OrangePiZero3 model. I managed to do it so you should too. for me it is: 3f sudo i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3f 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- I also use the lcdproc program to display the current time + install drivers for: hd44780 sudo apt-get install lcdproc lcdproc-extra-drivers Find in your system where you have the file: hd44780.so cd / find -name hd44780.so e.g. ./usr/lib/aarch64-linux-gnu/lcdproc/hd44780.so and add change the path to the file in the configuration : DriverPath=/usr/lib/aarch64-linux-gnu/lcdproc/ Example lcdproc configuration: file: LCDd.conf ## Server section with all kinds of settings for the LCDd server ## [server] DriverPath=/usr/lib/aarch64-linux-gnu/lcdproc/ Driver=hd44780 Bind=127.0.0.1 Port=13666 ReportLevel=3 User=root Foreground=no Hello="Welcome to" Hello="Armbian" GoodBye="Internet Radio" GoodBye="OrangePi3 LTS" WaitTime=5 ServerScreen=off Backlight=off Heartbeat=off TitleSpeed=4 ToggleRotateKey=Enter PrevScreenKey=Left NextScreenKey=Right ## The menu section.

I'm testing different firmware versions for OrangePi 3 LTS a bit and I have to mention that version: Armbian_community_24.11.0-trunk.202_Orangepi3-lts_noble_current_6.6.44_gnome-kisak_desktop.img It has a flaw that can cause some trouble for beginners, i.e. after installing, the system automatically goes to the suspend option after 15 minutes 🙂 Disabling the suspend option completely helps, but it then prevents you from using the suspend option by clicking the button on the board 🙂 This is probably an error related to both battery and mains power supply. https://discussion.fedoraproject.org/t/gnome-suspends-after-15-minutes-of-user-inactivity-even-on-ac-power/79801 but unfortunately this is not it 😞

It turned out that the sound card with the 3.5 jack output works properly and the cause of the strange earlier noises, crackles, etc. was probably the OrangePi 3lts power supply, although the specification stated: output 5V - 4A it probably wasn't 4A 🙂 I bought a different model and now everything is OK, the sound works properly. cat /proc/asound/allwinnerac200c/pcm0p/sub0/hw_params access: RW_INTERLEAVED format: S24_LE subformat: STD channels: 2 rate: 44100 (44100/1) period_size: 7350 buffer_size: 22050 this one is OK link I do not recommend this!!! link Ps. Is there any advice to eliminate the loud clicking in the speakers during music start and also during system start? The audio signal is supplied to the amplifier via the standard 3.5 jack output from the OrangePi3 LTS. The system uses Alsa / mpd / mpc sound ...?

I confirm the sound on the OrangePi 3LTS / internal card and the 3.5 jack output is very bad with noise. I can confirm the correct operation of the USB sound card based on the chip: Pcm2706 (can be read: 16-Bit Delta-Sigma Stereo DAC) link1 link2
