I need to extract audio from a HDMI signal. A mobile device is the player and the screen should stay active and the audio of the device should be disabled. Is this possible and how?
You can do audio extraction with ADV7625, ADV7626 and ADV7627

These are to complex/overdone for the application. I hoped there was an solution as a Audio codec/converter which accepts TMDS as input and covert it to SPDIF. I only need 1 digital stereo audio output. Video will not be used at all. Only thing is that the mobile device should leave it's screen active and switch off the internal speaker.
If video is not used at all then check out the ADV7612. It will decode the TMDS stream and extract the audio stream. You can ignore the pixel bus output. There is no audio codec that receive and extract the audio from and HDMI stream.
