    le51 got a reaction from guidol in Need support for the PecanPi DAC   
    I agree with Guidol's point of view.
     
    But, so far
    if you already have a tinkerboard lying on your desk if you know how to use etcher (or any other tool for creating a bootable disk) Then by following instructions given above and these on how to compile armbian you should be able to get your DAC up and running under armbian. And, maybe you will just have to adapt the "compatibility" line in the dts file ...
    I would be glad to help you further, but without having the tinkerboard, and without having this dac it's hard to do more ...

    le51 reacted to iamdrq in Orange Pi 4 Kernel 5.x.x rt5651 sound and bluetooth fixed   
    Oh,I fixed this problem spend 2 weeks,I finally heard sound from 3.5 mm jack (this jack is OMTP otherwise need keep press headphone button)
     
    I see this topic,and I compair https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/soc/codecs/rt5640.c and https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/soc/codecs/rt5651.c,this rt5651 not enable mclk and orangepi4"s rt5651 linked i2s1,the i2s1's SCLK_I2S_8CH parent not SCLK_I2S1_8CH defult and need set alsamixer in following(also use alsactl save this alsamixer state):
    amixer set 'HPO L' on amixer set 'HPO R' on amixer set 'HPOVOL L' on amixer set 'HPOVOL R' on amixer set 'HPO MIX HPVOL' on amixer set 'OUT MIXL DAC L1' on amixer set 'OUT MIXR DAC R1' on amixer set 'Stereo DAC MIXL DAC L1' on amixer set 'Stereo DAC MIXR DAC R1' on And I not familiar with electronics,I did some patch and hope this can help armbian fix 
    fix-i2s1-clk.patch orangepi4-rt5651.patch orangepi4-i2s_8ch_mclk.dts
    Armbian applied this patch to 'Armbian build system' and with minor tweaks,you can use it by 'Armbian build system' latest branch.

    le51 got a reaction from lanefu in Multiple audio in and out   
    Hi,
     
    I bought a module on aliexpress which is more or less the same as the audioinjector zero : https://www.aliexpress.com/item/1674210328.html
    Both use the wm8731 audio codec. It provides stereo line input, and microphone input (Note that uou can't use them simultaneously), headphone and stereo line outputs.
    Codec is supported by linux kernel.
     I've managed to get it recognized by armbian on a nanoPi K1 plus with 4.19.83-sunxi64 self build kernel (aplay -L and arecord -L have shown the interface) after some manipulations but unfortunately:
    1/ I had no sound output (didn't tried the record feature) , maybe because board is sold without any crystal oscillator soldered on it
    2/ I've lost the board :-( 
     
    Now some guidelines: the post I've mentioned above is really helpful
    - check that the i2s channel you want to use is enabled (status: "okay";)
    - see in /lib/modules/YourKernelVersion/kernel/sound/soc/codecs/ if snd-soc-wm8731.ko is there otherwise you will have to compile it
    - the dts file I've used for that (you will have to adjust it regarding your hardware) with "armbian-add-overlay wm8731.dts" :
    ## file wm8731.dts /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; fragment@0 { target-path = "/"; __overlay__ { wm8731: wm8731 { #sound-dai-cells = <0>; compatible = "wlf,wm8731"; status = "okay"; wm873x,format = "i2s"; }; }; }; fragment@1 { target = <&i2s0>; __overlay__ { status = "okay"; pinctrl-0 = <&i2s0_pins>; sound-dai = <&wm8731>; pinctrl-names = "default"; }; }; fragment@2 { target-path = "/"; __overlay__ { sound { compatible = "simple-audio-card"; simple-audio-card,name = "wm8731-hifi"; simple-audio-card,format = "i2s"; simple-audio-card,bitclock-master = <&codec_master>; simple-audio-card,frame-master = <&codec_master>; simple-audio-card,widgets = "Headphone", "Headphone Jack", "Microphone", "Microphone Jack", "Line", "Line Jack"; simple-audio-card,routing = "Headphone Jack", "RHPOUT", "Headphone Jack", "LHPOUT", "LLINEIN", "Line Jack", "MICIN", "Mic Bias", "Mic Bias", "Microphone Jack"; simple-audio-card,cpu { sound-dai = <&i2s0>; system-clock-frequency = <12000000>; }; codec_master: simple-audio-card,codec { sound-dai = <&wm8731>; system-clock-frequency = <12000000>; }; }; }; }; fragment@3 { target = <&i2c0>; __overlay__ { #address-cells = <1>; #size-cells = <0>; status = "okay"; wm8731@1a { #sound-dai-cells = <0>; compatible = "wlf,wm8731"; reg = <0x1a>; status = "okay"; }; }; }; }; Hope this helps.

    le51 got a reaction from guidol in [Info] FriendlyARM PCM5102A-Hat with NanoPi Neo under mainline 4.x.x and dev 5.3.3   
    I've made a breakout board. The small white IC, is an optocoupler and the non connected cables are for a midi in (but not yet finished) interface.
    From this breakout board, I will also connect the RCA cinch out.  
    Final goal is to run a zynthian synth on armbian (see https://zynthian.org/)
