Updating ROM doesn't do a trick. But latest update of XiiaLive lite work just perfect:)

By the way I think that I found out what cause the problem...
The station use the latest HE-AAC v2 with Parametric Stereo, at very low bitrate.

For some reason low bitrate was problem for previous versions of XiiaLive, but now, as I said, everything working well and I have 2ch instead 1ch, that suggest that new version have latest aac decoder.

Thanks for all your help and for doing great job.
