The result is that you can have a simple connection of the I2S lines and everythings works correct. If your adapter does not support that you will have to build small circuit that switches the I2S lines for Left/Right channels for DSD playback.<br /><br />Cheers<br /><br /> Thomas </td></tr></table><table><tr><td><a href="http://www.twistedpearaudio.com/forum/posts/m21444-What-about-new-XMOS-USB-module#post21444" ><img src="http://www.twistedpearaudio.com/forum/Themes/GreyGrey/icon_newest_reply.png" alt ="Go to last post" title ="Go to last post" /></a></td></tr><table>urn:twistedpearaudio-com:ftTopics:st1:tid3298:lmid20946:1Adding USB input to my DAC<table class="content postContainer_Alt" width="100%"><tr><td>You may want to check out this thread:<br /><br /><a target="_blank" rel="nofollow" href="http://www.diyaudio.com/forums/twisted-pear/250583-building-open-embedded-audio-applicance.html" title="http://www.diyaudio.com/forums/twisted-pear/250583-building-open-embedded-audio-applicance.html">http://www.diyaudio.com/...ed-audio-applicance.html</a></td></tr></table><table><tr><td><a href="http://www.twistedpearaudio.com/forum/posts/m20946-Adding-USB-input-to-my-DAC#post20946" ><img src="http://www.twistedpearaudio.com/forum/Themes/GreyGrey/icon_newest_reply.png" alt ="Go to last post" title ="Go to last post" /></a></td></tr><table>2014-04-30T15:54:51-07:002014-04-30T15:54:51-07:00kesgreen<table class="content postContainer_Alt" width="100%"><tr><td>You may want to check out this thread:<br /><br /><a target="_blank" rel="nofollow" href="http://www.diyaudio.com/forums/twisted-pear/250583-building-open-embedded-audio-applicance.html" title="http://www.diyaudio.com/forums/twisted-pear/250583-building-open-embedded-audio-applicance.html">http://www.diyaudio.com/...ed-audio-applicance.html</a></td></tr></table><table><tr><td><a href="http://www.twistedpearaudio.com/forum/posts/m20946-Adding-USB-input-to-my-DAC#post20946" ><img src="http://www.twistedpearaudio.com/forum/Themes/GreyGrey/icon_newest_reply.png" alt ="Go to last post" title ="Go to last post" /></a></td></tr><table>urn:twistedpearaudio-com:ftTopics:st1:tid3143:lmid20190:1old 16/48 usb receiver<table class="content postContainer_Alt" width="100%"><tr><td><div class="quote"><span class="quotetitle">Originally Posted by: Brian Donegan <a href="/forum/posts/m20188-old-16-48-usb-receiver#post20188"><img src="/forum/Themes/GreyGrey/icon_latest_reply.png" title="Go to Quoted Post" alt="Go to Quoted Post" /></a></span><blockquote>No, we are making some changes to other boards in the batch order, so there has been a slight delay.
