That is my suspicion also. I have tracked things through the exit of snd_pcm_open_file and found the substream pointer to be valid to that point. The null substream pointer seems to be coming in to a snd_pcm_playback_ioctl call that occurs after the file open (I suspect from a call to snd_pcm_hw_info in alsa-lib) Looks like I need to start adding debug printf's in alsa-lib too. I'm working on this as a background task while bringing up some new hw so progress is a bit slow :-( Steve -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
