music defaults to pin0

[rhubarbdog]

from microbit import *
import music

music.play('["c"], pin2, False)

plays music through the speaker on pin0 and to my external speaker on pin2

[rhubarbdog]

i have this device Kitronik GameZip 64 controler neopiexls are on pin0 external speaker pin2

this program seems to work gamezip.py.txt

but in bigger programs neopixels fail to light and the speaker latches on with a quiet buzzing noise

Do you have an example that fails?

[rhubarbdog]

Yes repository https://github.com/rhubarbdog/microbit-two-weeks it's my fortnight clone client server game.

Put host.py on one microbit and gamezip.py on the other. You'll need to edit gamezip.py and uncomment all lines with the word 'music'

the linked code doesn't seem to work either way - I get a set of 3 leds on the Ubit display, but nothing else. the 'Host set is rotating, and the other set is static. Can you make a simple this works, this doesn't work pair for a test case?

Hi @rhubarbdog, if you could provide a simple programme to replicate the issue it would help identify the problem.

As far as music.play() or audio.play() always outputting sound via pin0 I haven't been able to replicate this. I've tried it with a micro:bit V2 and using a Kitronik KLEF Piano, which connects the external speaker to pin0.

Running this code as a programme or in the REPL and I don't hear sound from the external speaker.

from microbit import *
import music

music.play(["c"], pin2, False)
audio.play(Sound.HAPPY, pin=pin2)

Did you test this with a micro:bit V2? Are you sure the sound you are hearing is not coming from the micro:bit on-board speaker? You can turn off the on-board speaker with speaker.off() to check.

this has been solved with firmware version 2.1.2
