That would be a better solution than pasuspender because then Pd would be playing "nice" with all the other sound apps concurrently. Latency might be slightly worse but I think for beginners at least the initial experience would be more positive, as many of these users are coming from OS X and Windows platforms where sound applications sharing the same sound card concurrently is expected behavior.<br> <br>I also vaguely remember the pulseaudio is only an issue with ALSA when there is no hardware mixer in the card. But my guess is that would be all cheap sound cards, since it has been the case with the built-in cards on all the Linux-based laptops I run into.<br> <br>-John<br><br><div class="gmail_quote">On Fri, Nov 13, 2009 at 6:50 PM, Hans-Christoph Steiner <span dir="ltr"><<a href="mailto:hans@at.or.at" target="_blank">hans@at.or.at</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div style="word-wrap: break-word;"><div><br></div><div>Is pasuspender something that could be integrated into the Pd-extended menu launch item somehow?
