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. http://codepad.org/nKNT4SyG 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.
