(and also why I get a > build up of static sound in the last 5-10 seconds before the xrun)? *if* the h/w can resample (and if any device could, this would be the one i would guess it would be), its probably just a poor resampling implementation, and possibly some interaction between that and the driver. by "poor" i refer to code quality, not the resampling algo itself. this card dates from roughly the switchover point when it started to become "the rule" that cheap h/w ran at a single SR and its driver resampled when necessary. they could just have done a poor implementation before eventually making their newer cards rely on driver resampling. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
