What kind of xruns - do you get warnings from 'audioio-db-client' or from
'audioio-alsa'...? In the former case it's the disk i/o subsystem that
cannot keep up, in the latter the kernel/cpu.
You could try to record with:
"-z:db,500000 -z:intbuf -b:1024"
and see if that helps.

It is possible that some component cannot keep up.
