[pulseaudio-discuss] Low latency applications

[Lasse Kärkkäinen]

Hi,

I tried to get as low latency as possible but there is a very 
significant delay. Could someone please have a look at this simple (and 
hacky) audio loopback test and point out if it could be changed to run 
at lower latency? Do not mind the shortcuts taken or the obvious 
distortion that occurs because capture and playback aren't synchronized 
- this is simply a minimalistic latency test.

Another similar test application written directly for ALSA runs with 
very low latency on the same system (with pasuspender), so it is not a 
hardware or driver issue. For the record, I am using generic USB 
microphone for capture and HDA-Intel for playback.
