No sure!
Sometimes, with the tda998x in HDMI mode, I get a black screen on my TV set. And, surprise, when I start the audio (playing something with vlc), the image appears!
I dumped all (known) registers in the audio and video subsystems (tda998x, dove lcd, kirkwood audio), and there is no difference between normal display and black screen. So, some audio event should interact with the HDMI display.
I don't think that the problem comes from the TV set, because, when there is a black screen, turning the TV off/on never makes it display normally again. Rebooting the cubox also lets the black screen. Only powering off/on the cubox could change the display back to normal.
Now, playing some audio stream gives me immediately a normal display.
Any idea?
