Same problem here - on Incredible S, brief click/blip every 30s or so. Logged this with HTC and got the standard reply. Anyway I did try a reset and did not install any apps, still the same problem. Have been watching this forum for similar issues, as the IS does not yet have Gingerbread, I was hoping this might fix it
Do you have the problem listening/watching to video? Aside from a slight delay/sync issue, I have no problem with video, only music playback. Have tried several music players, bluetooth 'fix' apps, you name it.
Had no problem on previous Desire HD, and no current problems with my laptop. Has to be an HTC software bug? Or poor HTC hardware? It's real annoying
