Just got this board on an A+ 256 with the latest Jessie and ran the script you provide. However, there is no blacklist file and although your test routine works, the only application that can see the board is Audacity
(which is using ALSA)
Audio device settings says ’ no ALSA device detected’. Alsamixer shows the DAC though. aplay -l shows it too.
I’ve tried all the tweaking I know to get the a default Alsa device with this card, but it just won’t work.
Any ideas??
TIA
