I would like to put an Android system in the car, I am searching info on the web, assuming of course, that I am looking ONLY to get a digital signal to send into a DSP.
There are a lot of cheap HDMI to TOSLINK and USB to TOSLINK devices on the market, but something still is not clear, my questions are:
1) Does the tablets manipulate the audio signal before get out thru HDMi or USB? I mean they use internal (and poor quality) DAC, then convert in digital again or the signal go straight in digital?
2)Those cheap converter do make digital-to-digital conversion without loss quality or have internal (and poor quality) DAC then convert again in optical signal?
