I am still searching what causes the problem, I now figured out that the underruns occur because appl_ptr = hw_ptr - so this is because appl_ptr is not moved forward. Are there any reasons for this? <7>DEBUG: p1 hw_ptr=0x3cdd43 (3988803) appl_ptr=0x3cebbc (3992508) jiffie=21775142 <7>DEBUG: p1 hw_ptr=0x3ce028 (3989544) appl_ptr=0x3ceea1 (3993249) jiffie=21775165 <7>DEBUG: p1 hw_ptr=0x3ce30d (3990285) appl_ptr=0x3cf186 (3993990) jiffie=21775188 <7>DEBUG: p1 hw_ptr=0x3ce5f2 (3991026) appl_ptr=0x3cf46b (3994731) jiffie=21775212 <7>DEBUG: p1 hw_ptr=0x3ce8d7 (3991767) appl_ptr=0x3cf750 (3995472) jiffie=21775235 <7>DEBUG: p1 hw_ptr=0x3cebbc (3992508) appl_ptr=0x3cf750 (3995472) jiffie=21775258 <7>DEBUG: p1 hw_ptr=0x3ceea1 (3993249) appl_ptr=0x3cf750 (3995472) jiffie=21775281 <7>DEBUG: p1 hw_ptr=0x3cf186 (3993990) appl_ptr=0x3cf750 (3995472) jiffie=21775304 <7>DEBUG: p1 hw_ptr=0x3cf46b (3994731) appl_ptr=0x3cf750 (3995472) jiffie=21775328 <7>DEBUG: p1 hw_ptr=0x3cf750 (3995472) appl_ptr=0x3cf750 (3995472) jiffie=21775351 <3>ERROR: p1 XRUN B! avail = 4446 stop_threshold = 4446 jiffie_diff=23 <7>DEBUG: playback trigger (1): cmd=stop <7>DEBUG: trigger stop jiffies=21775351 <7>DEBUG: trigger stop jiffies difference =124742 <7>DEBUG: - pcm_timer_stop <7>DEBUG: pcm prepare I will go on searching for the reason, but I am thankful for any hint... _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
