Changing data source sometimes alters pitch

[pete-789]

I have two streams in my internet radio - a URLStream and an HLSStream. When I change station I 'end()' the stream that is playing at the time, before the 'begin(url)' of the new station.

Sometimes the new station will play audio at the proper speed but at a higher pitch. I think this is when going from an HLSStream to a URLStream, maybe because of a change in the sampling rate?

I've tried adding addNotifyAudioChange(i2s) to both streams but it hasn't made any difference.

What's the best way to fix this? Many thanks!
