Buffer underflow issue #55

Closed medamarko closed 6 years ago

medamarko commented 6 years ago

Constantly getting buffer underflow.... Im using ESP Wroom 32 module. Do i need Wrover with PSram to run this app?

I ran into the exact same issue.

Calling i2s_write instead of the deprecated function i2s_push_sample seems to fix it for me.

I'll create a PR with the changes.
