ALSA on FriendlyARM

Does anybody have alsa running on friendly Arm board? I would appreciate
that you could give me some information.

Advanced Linux Sound Architecture?

I think it's build by default on kernel don't it?

All you have to do is use the /dev/dsp bus to play some sound.

regards

Yes, I have /dev/dsp working right, but it only works if I use an
application that access the device directly, like madplay.

But I want to work with Linphone which is ALSA (Advanced Linux Sound
Architecture) controller based. It cannot access the hardware directly, I
have to create a sound card controller in /proc/asound/card0 that allows me
to manage the sound with amixer (from ALSA tools)

In busybox I selected to use OSS devices for ALSA which did create a sound
card in /proc/asound/card0.

However, when executing the command amixer (from ALSA tools) I have this:

    [root@arm-linux bin]# ./amixer scontrols
    ALSA lib control.c:739:(snd_ctl_open_noupdate) Invalid CTL default
    amixer: Mixer attach default error: No such file or directory



Anybody knows how to avoid this error?
