ALSA on OMAPL38

Other Parts Discussed in Thread: OMAPL138, OMAP-L138

I would like to use the ALSA on the OMAPL138 EVM for testing . When I list devices with aplay -l I get the response  "aplay: device_list:223: no soundcards found..."

looking at /proc/asound...

/proc/asound> ls -l

total 0

lrwxrwxrwx 1 root root 5 Feb 26 19:43 EVM -> card0

dr-xr-xr-x 4 root root 0 Feb 26 19:43 card0

-r--r--r-- 1 root root 0 Feb 26 19:43 cards

-r--r--r-- 1 root root 0 Feb 26 19:43 devices

-r--r--r-- 1 root root 0 Feb 26 19:43 pcm

-r--r--r-- 1 root root 0 Feb 26 19:43 timers

-r--r--r-- 1 root root 0 Feb 26 19:43 version
