Hi,
I was wondering if anyone has been able to get SPDIF input working on
this CM6206 chip?
I have no way of checking but the SPDIF out appears to be working as it
lights up, but despite various options in arecord I cant seem to get the
digital input. I have set the output device to 48000 and 41000 and
matched in a record but neither settings work.
Alsamixer doesn't define a spdif capture device but gives several pcm
options as below:

I also found when I upgraded to the latest Alsa version 1.0.23 my system
couldn't boot with the card plugged in. Yet .22 runs o.k?
Any help would be appreciated.
Thanks
