[PD] tried but cannot sync A/D/A if I try to set delay>50

[Pedro Lopes]

Do you really need plain alsa by any reason?

If not, switch to jack audio server, then in jack you can configure the
desired "latency parameter" easily (use qjackctl as GUI frontend for  jackd
itself). Then configure a higher latency that will ultimately free more
CPU cycles and glitch less.

At least, its the way I work =P

Best regards,
Pedro Lopes
