Problem connecting on internet radios

Hello,

I have a problem for a long time, and I don't know how to solve it.
My config : LMS 7.9.2 on a Synology NAS.

I can stream easily from spotify to LMS, and some internet radios are working, but lot of them are not.
When I play an internet radio (copying the url, from tune in, from the radio category...) The title and the picture are displaying, but no sound at all.

I don't know where I can find logs to help to find a solution?

Thank you in advance
