From the error message you posted about this bug, it looks that driver is trying to call prepare() operator on a substream that is still in SNDRV_PCM_STATE_RUNNING state. Perhaps Jaroslav could tell us if this can happen if hardware pointers are not updated anymore (because sb16 DMA engine gets stucked somehow). Do you get an XRUN message in /var/log/messages?
Excellent question!
1) No xrun messages in /var/log/messages, but.... 2) My program intentionally causes an overrun on input once every 0.5 seconds. It catches this condition, and recovers by calling snd_pcm_prepare(). It does not print a message about this (unless super-specially requested). I realize that other programs may cause far fewer overruns, which may (or may not :-) explain why others don't suffer quite so badly from this bug. Even so, it remains a bug. An overrun shouldn't take down the whole system. 3) As previously indicated, if I load the system, I can cause a few audible underruns on output. But doing this has no discernible effect on the incidence of the bug in question. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
