To: linux-kernel@vger.kernel.org Date: Tue, 01 Mar 2011 01:58:43 +0100 From: Uwaysi Bin Kareem Message-id: User-Agent: Opera Mail/11.01 (Linux) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 932 Lines: 23 Hello. I have shaved a kernel for features I suspected to add to os-jitter, to get the lowest possible latency from it. The kernel is 2.6.36-zen0 The .config is http://www.paradoxuncreated.com/tmp/.config What happens is, if I set my audioapp, (renoise) to extremely low latencies, (96khz, 8 samples buffers x 2), the audio seems to be distorting and speeding up, while having periods of normal playback. With other kernel configurations, I have just experienced, glitches, which is typical of buffer underruns. This kernel config though, reduces the overall os-jitter, so I could push the latency much lower. However then I stumbled on this problem.
