Problem Description

In my internet radio project I am trying to use external 23LC1024 SPIRAM for ringbuffer

    ESP.setExternalHeap();                             // Set external memory to use
    ringbuf = (uint8_t *) malloc ( RINGBFSIZ ) ;       // Create ring buffer
    dbgprint ( "External buffer: Address %p, free %d\n", 
                    ringbuf, ESP.getFreeHeap() ) ;
    ESP.resetHeap();

Basic test as well as virtualmem.ino sketch works with no issues but buffer is empty.

Is there anything additional that needs to be added in the code? Or is it a bug?
