New PB sound lib (MiniAudio) limited to 32 simultaneous channels?

It seems after 32 sounds at the same time PlaySound() does not play new sounds:
https://lebostein.de/temp/mbox.ogg
Code: Select all
InitSound()
UseOGGSoundDecoder()
LoadSound(0, "mbox.ogg")
For i = 1 To 60
channel = PlaySound(0, #PB_Sound_MultiChannel): Debug channel
If channel: SetSoundFrequency(0, 6000 + i * 300, channel): EndIf
Delay(50)
Next i
Delay(2000)
Output Mac OS (after 32 sounds the end has been reached)
2 (starts with channel 2)
3
4
...
...
33
34 (last PlaySound with a return != 0, but it seems it is impossible to set the frequency of this last sound)
0
0
0
0
0
0
...
Output Windows (all 60 sounds are played)

Ok, an older version of MiniAudio is probably the reason for this...
I have scroll down the changelog of MiniAudio and it seems the number of channels have changed with v0.11.0 (from 2021-12-18) from 32 to 254
Increase MA_MAX_CHANNELS from 32 to 254.

Perhaps this limitation should be mentioned in the PB documentation.

I'm more curious why PB is using Miniaudio from December of 2121
@Fred, is it perhaps for older platforms or the like?

Ah, I see. Is the channel limit hardcoded on the PB side? If so, a parameter to InitSound() would be good in this case I think.
