<div>Hello Pierre,</div> <div> </div> <div>Thanks for your inputs.</div> <div> </div> <div>I will test this once I have the hardware available with me and keep you posted on this.</div> <div> </div> <div>Regarding the tool, I am not sure if my processor has enough bandwidth to run those tools on the platform. Need to find out a way to simulate it on host.</div> <div> </div> <div>-Rgds</div> <div>Vallabha<br><br></div> <div class="gmail_quote">On Fri, Jul 29, 2011 at 12:04 AM, pl bossart <span dir="ltr"><<a href="mailto:bossart.nospam@gmail.com">bossart.nospam@gmail.com</a>></span> wrote:<br> <blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">On Wed, Jul 27, 2011 at 12:55 AM, Vallabha Hampiholi<br> <div class="im"><<a href="http://vallabha.pa/" target="_blank">vallabha.pa</a>@<a href="http://googlemail.com/" target="_blank">googlemail.com</a>> wrote:<br></div> <div class="im">> We are now running PA with high resolution timers enabled in the kernel.<br>><br>> Yet I still can hear the audio glitches.<br>><br>> Attached are new traces.<br><br></div>I: alsa-sink.c: Using 16.0 fragments of size 8192 bytes (46.44ms),<br> buffer size is 131072 bytes (743.04ms)<br>I: alsa-sink.c: Time scheduling watermark is 20.00ms<br><br>This seems really wrong.
