My Rpi 2 installed with OpenElec 5.08(official) was running fine with DAC+ .
After swapping-out the DAC+ with DAC+ Pro, OpenElec won't show the ALSA driver anymore under the menu Settings->System->Audio Output. I tried repeating the driver installation steps documented at Hifiberry site and rebooted. Still can't see ALSA driver.
I swapped-back-in the DAC+ card that I was using, everything went back to normal ie. I can see the ALSA driver again.
What else I should try? The debug messages from running "vcdbg log msg" looks the same when I plugged in DAC+ or DAC+ Pro, nothing extraordinary.
OpenElec 5.08 cannot detect DAC+ Pro
