[pulseaudio-discuss] Distribution kernels and glitch-free (Packagers, read this!)

[Hynek Hanke]

Dear Lennart,

I've set all the connection parameters to the values you
have suggested by default. This is

pre_buffering = (uint32_t) -1;
maxlength = (uint32_t) -1;
prebuf = (uint32_t) -1;

and PA_STREAM_ADJUST_LATENCY into the flags.

The results are that on the 0.9.14 Pulse Audio that before
reported a 20ms latency ( = 0.0+2*9.98+0.0 ) was now
reporting 40ms ( = 0.0+2*20+0.0 ) on the same target length
of 400. We couldn't get better than 40 by increasing or decreasing
the target length.

When we got 0.9.15 fully working now, I can confirm what Luke Yelavich
says, that the latency increased (on the same parameter configuration
described above). In our setting it is about 200ms (= 80.0 + 2*20 + 80.0)
and by modifying just tlength, we are not able to make it lower.

With regards,
Hynek Hanke
