I've been working on the WTV020-SD-MINI for about 1 week but to no avail. After reading up almost everything posted on the web and utilizing all the files that were shared which proved to be working, I'm still not getting any sound except a few bleeps when the busy pin's LED blinks. I'm currently using a 1GB Samsung uSD card and I think that it is the culprit.
I will be changing this uSD card to a Sandisk soon and hope it will work, fingers crossed
Will get back to you guys soon after changing the uSD.
