Can you ssh in to the Pi and paste the output from the command: tvservice -a
Below is mine:
PCM supported: Max channels: 6, Max samplerate: 192kHz, Max samplesize 24 bits.
AC3 supported: Max channels: 8, Max samplerate: 48kHz, Max rate 640 kb/s.
DTS supported: Max channels: 8, Max samplerate: 48kHz, Max rate 1536 kb/s.
Sorry for the delay, here are my results:
