[alsa-devel] Fwd: Issue on Linux 4.12-rc7 on iMX6 based board [SOLVED]

[gianluca]

What did I do to fix this issue:

1- apt purge alsa-utils
2- apt install alsa-utils

Now everything is working as expected. Maybe some misconfigured stuff to 
have a (strangely enough) high value for property mixer and other stuff...
