<p class="MsoNormal"><span style="font-size:12.0pt">- The message ‘unknown audio API specified’ is displayed in the subprocess pd window.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt">- I have the two audio outputs of the subprocess wired to a 2 channel [dac~], and there are no audio inputs to the subprocess.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt">- The parent process is using PortAudio, and the subprocess appears to (correctly?) have no audio API selected.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt">- The subprocess Audio Settings show that the input device is unchecked and is called ‘input device 1’;</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt">- The corresponding output device is checked and says ‘(same as input device)’.</span><o:p></o:p></p>
