Ok adding alsa-devel to CC, may be the issue is known. Eric, from later messages you only experience the problem when bdl_pos_adj isn't set to 1 right? Anyway Frank said that his bdl_pos_adj is set to 32 on two machines (hda-intel), and on one of them the problem happens, while in the other not. I guess we could have a problem then on commit 7b3a177b0d4f92b3431b8dca777313a07533a710 > > See you, > Eric > -- []'s Herton _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
