If you've seen my earlier thread about the hissing problem that I was having with my shiny new RME PST and how I eventually decided it must be faulty because the same symptons appeared on both an old via chipset board and my new Asus P8P. RME agreed and sent me a new card. I stuck it in this afternoon and.....exactly the same. Played some .wavs back thorugh winamp and the hissing noise was still there. Put a cd in and I cant get anything from winamp other than the song list. No sounds (I'm new to winamp). Thought I'd try win media player for the cd and not only did I have sound but the hissing had disappeared. Encouraged I then tried my ripped .wavs and they sound great too. Obviously this RME card (and probably the one I've sent back too ) is okay but why does it sound so bad in winamp and why dont I get cd direct sound?
