Hi Takashi,

Proposed second revision of the patch that fixes the initialization of CSC3551 on the UM5302LA laptop. Patching the DSDT table is not required since ASUS did add _DSD entry. Nothing new introduced but reused work started by Stefan B.

Currently there is no official firmware available for 10431A83 on cirrus git unfortunately. For testing used 104317f3 (which is also seems on i2c bus):

$ cd /lib/firmware/cirrus/ && \ for fw in $(find ./ -name '*104317f3*'); do newfw=$(echo $fw | sed 's/104317f3/10431a83/g'); echo echo "$fw -> $newfw"; ln -s $f $newfw; done

With the patch applied to 6.6.0 and obviously symlinks to 104317F3 FW, speakers work and to my surprise they sound quite good and loud without distortion.

Probably confirmation from the cirrus team is needed on firmware.
