Sounds like you've narrowed the problem down to a performance issue with NFS writeout - it's probably having trouble keeping up with your I/O rate. This isn't 100% surprising with smaller systems, sometimes tuning the NFS configuration can resolve the issue but sometimes the hardware is just underspecified. arecord is a pretty basic program and doesn't try terribly hard to recover from errors. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
