I just read the mail of other user with this problem. As I pointed in that
mail the codec seems to be AD1885 or newer (AD1885 is 0x60 and this machine
seems to have 0x61, maybe a revision, didn't have time to look for data
The AD1885 needs EAPD control (default_ops) but as the coded wasn't detected
null_ops are used and the amplifier is blocked giving almost no volume.
