How to start a sound&microphone on the Orange Pi Zero 2+ H3? root@orangepizeroplus2:/# aplay -l aplay: device_list:268: no soundcards found... root@orangepizeroplus2:~# uname -a Linux orangepizeroplus2 4.11.5-sun8i #3 SMP Thu Aug 3 08:36:37 CEST 2017 armv7l armv7l armv7l GNU/Linux root@orangepizeroplus2:~# lsmod Module Size Used by can_raw 16384 1 bluetooth 270336 0 qmi_wwan 24576 0 qcserial 16384 2 usb_wwan 16384 1 qcserial sun8i_codec_analog 24576 0 snd_soc_core 122880 1 sun8i

There was a new problem. The system worked with a flash drive. I transferred to internal memory. And orange stopped booting! If I disconnect the interrupt pin, orange is loaded ... In what there can be a problem, how it to win?

If you find the time, try different pins for interrupts, for me it is not entirely clear why it was PA2, but when connected to other pins, orange could not reboot

Everything worked! I tried various pins to interrupt and with PA2 worked without errors. Thank you all for the help!

After all the fixes, errors ceased to appear and the interface can0 appeared!

My connection with the module: 4 VCC 6 GND 19 - GPIO 15 - MOSI 21 - GPIO 16 - MISO 23 - GPIO 14 - CLK 24 - GPIO 13 - CS0 It's right? Is it necessary to connect a pin-INT on the module mcp2515, or without it to worked?

What pin should I choose?

Need help! I'm trying to connect the mcp2515 module to the Orange Pi Zero 2+ H3, but I can not. Dmesg wrote: [8.572220] mcp251x spi0.0: Can not initialize MCP2515. Wrong wiring?
