Orange Pi Zero with audio (ARMBIAN 5.38)

[VihangaA]

HI! Im new to Orange Pi Zero. I want to connect a speaker to my Orange Pi Zero. I went through some websites and forums, there saying that use pin 7 and 8 to speaker. I connected pin 7 to + and pin 8 to -. Then I entered 'speaker-test'. But it doesn't get any sound.

root@orangepizero:~# speaker-test

speaker-test 1.1.3

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 256 to 262144
Period size range from 128 to 32768
Using max buffer size 262144
Periods = 4
was set period_size = 32768
was set buffer_size = 262144
 0 - Front Left
Time per period = 2.744307
 0 - Front Left
Time per period = 2.782264

So how can I test audio in my Orange Pi Zero? Thank you

Which header are you connecting to? Single row or double row?

You need to connect between pin 7 or pin 8 and pin 2 on the single row header...

Hi psz! Thanks for the reply. I connected speaker using pin 8 and pin 2 in single header, did speaker-test. But it didnt work. (also tried pin 7 with pin 2).

 

When I tried to play an audio I got this.

root@orangepizero:~# aplay song.mp3
Playing raw data 'song.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono

I don't think aplay supports MP3. Use mpg123 for that..

yeah, at the end I had to install mpg123. Now it works.  also had to connect an amplifier to the speaker.
