Interesting... seems there are no sound relevant changes after v4.9.

Looks like there are only three commits after v4.9 for sound/soc which 
are built for Nokia N900:

e411b0b5eb9b65257a050eac333d181d6e00e2c6
e7aa450fe17890e59db7d3c2d8eff5b6b41fc531
63c3194b82530bd71fd49db84eb7ab656b8d404a

Maybe something not related to sound/soc could broke it?
