Hi,

I am trying to enable a software mixer (using ALSA and dmix) on an OMAP3 based embedded target board using the twl4030 codec.

When I try to play audio using the command,

# aplay -D playback rec.wav

I am getting the following error:

ALSA lib pcm_direct.c:1098:(snd_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0'

Do you have /dev/snd/timer device?
