I am having trouble outputting sound on Linux using SSM2603.
The SSM2603 device driver loads normally.
It is also registered in ALSA sound card list.
However, "input / output error" is raised in "alsactl init". ("amixer" is also the same.)
It plays when I play wave file with "aplay" but it does not output to "R/LOUT pin" of SSM2603.
