<div>Hi Scott, </div>
<div><br>
</div>
<div>Are you on Windows? Did you specify the -in and -out flags? When I last tested it, the non-ASIO build doesn't support multi-channel audio. Also, the -dac flag needs an extra character before the number.</div>
<div><span style="font-size: 13.3333px;"><br>
</span></div>
<div><span style="font-size: 13.3333px;">If you start the ASIO build of ChucK like this, it works.</span></div>
<div><span style="font-family: verdana, arial, "sans serif"; font-size: 12px; background-color: rgb(239, 239, 239); color: blue;">chuckasio --dac_3 --adc3 --in8 --out8 test.ck</span><span style="font-family: verdana, arial, "sans serif"; font-size: 12px; background-color: rgb(239, 239, 239);"> </span></div>

<div><span style="font-size: 13.3333px;"><br>
</span></div>
<div><span style="font-size: 13.3333px;">Here, 3 is the audio device number. </span>See http://electro-music.com/forum/topic-69370.html<a href="http://electro-music.com/forum/topic-69370.html" target="_blank" style="font-size: 10pt;">http://electro-music.com/forum/topic-69370.html</a></div>

<div><span style="font-size: 10pt;"> Hope this helps,</span></div>

<div class="">Dear chuckians…</div>
<div class=""><br class="">
</div>
<div class="">This is bizarre… I was sure I have done this in the past, but it isn’t working and now I’m a bit flummoxed…. Any ideas here?</div>
<div class=""><br class="">
</div>
<div class="">PS: I’m trying to route channels 0 and 1 of a stereo .wav file to dac channels 2 and 3. Should be simple. So why doesn’t this work??</div>
<div class=""><br class="">
</div>
<div class="">I realize that I could just spit it into mono files… but why? I thought SndBuf supported up to 8 channels.</div>
