I found out that an underrun occours and so the pcm_prepare function  
for pcm_direct is called and then pcm_start_dshare is called. Both  
functions returns without any error but the playback path is blocked  
in the snd_pcm_wait_nocheck function. I read that there was an similar  
problem before in the group but i didn't found any solution. Is this a  
problem in the driver and how can i go forward to fix it. The codec is  
a tlv320aic3x-audio. Thanks for your help.

best regards
Harald
