I indicated last week that this setting is not ok.
Either you are setting the number of fragments to a ridiculously high
value in daemon.conf, or your hardware cannot handle longer periods.
Either way, you will end-up with an audio interrupt rate that is
inconsistent with the latency settings you have specified; a ~5s
latency isn't going to help at all if the alsa interrupts occur every
I know that the OMAP drivers were updated to remove these ALSA
interrupts completely (need kernel 2.6.38+), this is something you may
want to look into to remove audio wakes
