<div><div style="font-size:12pt;font-family:times new roman,new york,times,serif">Sorry to take so long to reply. Pulseaudio was not installed on my system, but I installed it to try the code change mentioned below. It did not work for me. I also installed jackd but again could not use another audio source concurrently with ChucK. I did find that all works as I would like with Windows, but I am resistant to using Windows instead of Linux. Might have to swallow hard and use Windows to get through this course. Thank you for all the help.<br>

<div><div dir="ltr"><div><div><div>pulseaudio should usually work out of the box because most linux desktop distributions have this installed and configured, so it should be nice for beginners.<br><br>But musicians etc. / linux music distributions usually use jackd.<br>
</div><br></div><div>Apart from that alsa allows to create virtual devices to be routed through pulse or jack for those who know how to do it.<br>So alsa would be a good choice for all, but unfortunately desktop distributions don't come with alsa on top of pulse (from what I remember).<br>
<br></div>So there should be a choice between all these systems, probably with default to pulse and a BIG comment at a prominent place saying latency etc. may be bad and using jackd would be better. Users who can install jackd should also be able to choose a sound device in chuck.<br>
</div><br>General rule: choose a good default for beginners and allow advanced configuration for experts.<br></div><div><br><br><div>On Tue, Nov 5, 2013 at 11:51 PM, Morgan <span dir="ltr"><<a rel="nofollow" href="mailto:morganiser@gmail.com" target="_blank">morganiser@gmail.com</a>></span> wrote:<br>

"We need to edit one of the files to allow audio mixing through<br>
PulseAudio, so that playing ChucK will not block other audio sources<br>
such as the sound in the course videos.<br>
<br>
Use a text-editor (preferably one that shows line-numbers) to open the file:<br>
<br>
kate RtAudio/RtAudio.cpp<br>
<br>
Find line 5660:<br>
<br>
sprintf( name, "hw:%d,%d", card, subdevice );<br>
<br>
Revise this to read:<br>
<br>
//sprintf( name, "hw:%d,%d", card, subdevice ); // commented out<br>
sprintf( name, "pulse" );<br>
<br>
Find line 5699:<br>
<br>
int openMode = SND_PCM_ASYNC;<br>
<br>
Revise this to read:<br>
<br>
int openMode = SND_PCM_ASYNC;<br>
printf( "pcm name %s\n", name ); // line inserted<br>
<br>
Save the file and close Kate (or whatever text-editor you used)."<br>
<br>
<br>
THEN compile etc<br>
<br>
I believe these directions should either be part of the linux readme<br>
or better still be scripted into the source... ubuntu/mint being the<br>
most popular distros thse days.<br>
