Cracking noises and some playbacks stop #887

After switching from Release 3.0.8 to 3.0.12 i had two problems:

Playback for some mp3 stops after a few seconds
I hear a random cracking noise - 3.0.8 had also some cracking noise, but very very quiet, with 3.0.12 it is very loud.

Nothing special in the debug output. Anyone has the same problem?

PS: @schreibfaul1 awesome library!

Im also having issues with this. Would you be able to share your code? and are you playing local files or streaming them

In the old version, the audio.loop() did everything. Since the WiFiClient is not blocking-free, I have moved the part responsible for decoding and I2S "feeding" to an extra task. This way many streams, especially m3u8, run more smoothly. This relieves the audio.loop(), which runs on core 1 by default. It may be that there is not enough time for other tasks, in which case a vTaskDelay() 1...10ms provides a remedy.

Otherwise, it may be that in some projects core 0 is now overloaded, e.g. by your own tasks, in which case the audio task can be moved from core 1 to core 0. audio.setAudioTaskCore(uint8_t coreID)

Adding vTaskDelay has solved the issue for me! Thankyou!

Yes, the vTaskDelay(1); fixed the crackings also for me, thank u.

But i still need to downgrade to 3.0.8 to play a mp3 that stops playing (or is quiet until the end) with 3.0.12. No useful information with audio_info. And the end of the file, you could here something and then audio_eof_mp3 is called.
