<br>&gt;&nbsp;&nbsp;kids all initiate Denemo playback simultaneously. So I don&#39;t recall<br>&gt; exactly what the RAM and swap impact is.&nbsp;&nbsp;But the CPUs are both<br>&gt; usually hovering right up there between 98% and 100%.<br><br>
I don&#39;t have experience with thin clients. Do other audio applications<br>do this?</blockquote><div><br>Not sure.&nbsp; We have not tested any other audio programs across the network, other than a quick cursory test of YouTube, which I *think* does not play audio across the network.&nbsp; The guy who built our server says that he thinks that there are issues with edubuntu and thin client networks and audio.&nbsp; We are going to have to experiment more.&nbsp; I am just now rushing to get out of here before the guard kicks me out.

</blockquote><div><br>Well, AFAIK, timidity is the vehicle that carries the audio signal over the network, as far as I am able to gather from this behavior:&nbsp; timidity seems to start whenever we hit play in denemo; and if kids hit playback all at once, both CPUs go to near 100% capacity until we do
<br><br>$ sudo killall -9 timidity<br><br>and then the CPU load once again quickly drops.&nbsp; <br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
 In denemo .75 the interface waits for<br>timidity to successfully quit before the interface responds. </blockquote><div><br>That is *really* interesting, because we are able to have several students play their compositions at once *so long as* we wait at least a few seconds between intiation of playback.&nbsp;

<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I don&#39;t know if that is part of what is<br>causing the issue or not. I would test if timidity can be launched
<br>simultaneously amongst the thin clients first.</blockquote><div><br>k, any suggestions for how to launch timidity?&nbsp; I&#39;m guessing just <br><br>$ timidity<br><br>would probably do it.&nbsp; But maybe timidity needs a file to play?
<br><br>BTW, do you mind me asking what time zone you are in?<br><br>Thanks tons for your interest in our school!!!</div></div><br>
