DAC2 HD - Failed to open "alsa" Error

Hello,

I have an issue with my DAC2 HD and Volumio (with raspberry pi 2b). I have red posts with similar error but didn’t find solution for fix it in my case.

When i play a track, i have an error Failed to open “alsa”[alsa]; Failed to open ALSA device:“hw2,0”, no such file or directory
My audio output is configured with 2S DAC : On / DAC Model : HifiBerry DAC2 HD

If i put the I2S DAC Off and “snd_rpi_hifiberry_dacplushd” as audio output, and then i reboot, it is working but i imagine it is not the good configuration.

If i put back I2S DAC on, sometimes it is working after a reboot, but a reboot later, the issue is coming back.

For information :
