that doesn't work and I've read all the documentation. I've tried a lot of ways to make this work but it always show all the tags and not just audio. also for what I'm doing I need them to be listed like in detail page and not in cloud.
Then you don't want that code. Probably {jrCore_search.... is the code you're after. If you tag an audio file with 'avacardo' and 'bannana' then on the audio item it will have those tags shaped like this
audio_tags
,avacardo,strawberry,
A simple call would be
{jrCore_list module="jrAudio" search1="audio_tags like %avacardo%"}
