Hi @Yasmina_Lee,
Thank you for reaching out and I’m sorry to hear you’ve been experiencing difficulties with playback.
Can you please confirm that Tidal playback works with your endpoints, but local playback (in particular, with lossy files) fails on your NAS?
If this is the case, we suspect you may be experiencing problems with ffmpeg. I suggest you follow the steps listed in the thread linked below, and reach out if the team can provide any further help or clarification. Thank you!
