Hello,   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.   Regards, Namio
