I'm new to Orange Pi Zero. I want to connect a speaker to my Orange Pi Zero. I went through some websites and forums, according to them 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).
(I use Armbian 5.38, 0.5W 16 ohms speaker. 5V 2A power supply for Orange Pi Zero)
When I tried to play a audio on Orange Pi Zero I got this.

root@orangepizero:~# aplay song.mp3

Playing raw data 'song.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono

When I did speaker-test I got something like this.

root@orangepizero:~# speaker-test

speaker-test 1.1.3

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels

Alsamixer looks like this.

There was no file called ".asoundrc", so I created.

pcm.!default{
type hw
card 0
}
ctl.!default{
type hw
card 0
}

Then I reboot and play a sound again. But then it gives an error like this

root@orangepizero:~# aplay song.mp3
aplay: set_params:1299: Sample format non available
Available formats:
- S16_LE
- S32_LE

When I tried speaker-test again it runs like above mentioned, but no sound How can I sort this out? Thanks
