NEED HELP . PI ZERO W + ADAFRUIT 1334A no output on UpnP server .Everything else works

Volumio recognises the audio stream but the dac is not able to decode it . This problem didnt exist in the earlier releasesof Volumio. The bit Depth of audio stream is indicated as 24bits , whereas I am only sending a 16bit depth Audio . This results in just a static noise output from volumio . The Upnp was working great prior to 2.4 release . Now it doesnt work . Pls Help .
