Most modern disks can read/write at least 40MB/sec, theoretically: 40 * 10^6 [Bytes / sec] / (48000 [samples / sec] * 4 [bytes / sample / channel]) = 208 mono-channels Is the filesystem that you record to NTFS? There are some odd issues, that some have been reported on #ardour IRC. I don't know the details but with some version (or option) of the linux driver disk read/write are always blocking with the effect that disk access can stall the application for seconds. If not NTFS, the only other thing that comes to mind is bus: Maybe the internal disk in this box is connected via USB and you've plugged some mouse into the same USB bus which forces it to 1.1 or something. > Question: what info should I capture and email to > get appropriate help? for starters: cat /proc/mounts lsusb -t ciao, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
