Hi, I am working with Adobe integrations at iconik.io and the most common issue we see is that there is a mismatch in audio channels in the source material and the proxy.

The proxies we generate in the cloud are made to support web browser playback and for that reason contain 1 track of 2 channel audio.
It is possible to upload a proxy that has the same audio channel mapping as the source file, in a format called PPRO_PROXY,
This format would then be preferred by the panel, and the web playback proxies will not be used.
If the audio channels do match up but the original still does not link up, please contact us through https://app.iconik.io/help/support/
and we can schedule a call to try to figure out what’s not working.
Best,
Fred
