Quoting David Henningsson <address@hidden>:


I've thinking about a change in the PulseAudio driver, changing
bufattr.maxlength from period_bytes to -1. What this means is basically:
if PulseAudio finds out that the specified buffer length (i e latency)
can't be satisfied (usually it tries and receives a drop-out), it will
use a bigger latency. The current behavior is to make drop-outs instead.

This is somewhat a matter of taste with pros and cons in both camps, but
I'm thinking that since PulseAudio isn't low-latency as in good live
real-time playing anyway, the PulseAudio driver will probably be used
more when FluidSynth is just a MIDI file player, and in that case,
bigger latency is probably preferable to drop-outs.

What do you think?

What about adding a boolean setting, something like audio.pulseaudio.auto-latency and set it to a default of TRUE or something like that? I'd be fine with what you suggested also though.
