I can only see that damn old "cannot create graph" error message.I already put down some significant amount of testing into this, and figured out that there seems to be some kind of problem connecting the "PCTV USB2 2821 Crossbar" audio output (pin 1) with the "PCTV USB2 2821 Audio" microphone input (pin 0). (This has been tested using GraphEdit).Just to be clear: the video track is fine - just the audio cannot connect.So my question to MediaPortal users is: can anyone post a screenshot of a working graph for that device?--- in-depth details ---What's happening is quite interesting: it seems that in my machine, if I create the filter "PCTV USB2 2821 Audio" from the "Audio Capture Source" group in GraphEdit, the graph connects, although I have no sound.If I create the filter from the filter "PCTV USB2 2821 Audio" from the "WDM Streaming Capture Devices", then GraphEdit is not able to connect them. The exact error message is:"These filter cannot agree on a connection. Verify type compatibility of input pin and output pin. (Retun code: 0x80040217)"Just as a reminder: for the Video, the WDM filters work just fine. We are just talking about the audio here.It is like something is wrong with the WDM side of that filter, but I need some kind of reference here.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" />--- even more in-depth details, obtained after some investigation ---This is the log from the graph creation attempt:The programmer in me whispered: "Use the Source, Luke". <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" /> After consulting the SVN repository (<a href="http://mediaportal.svn.sourceforge.net/viewvc/mediaportal/trunk/mediaportal/TVCapture/Graphs/GraphHelper.cs?view=markup" target="_blank">see code</a>), this is what the GraphHelper class has on that "FindUniqueFilter" method:...meaning that MP only supports devices that have a filter moniker of the form:"@device<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />np:\\?\usb#vid_2304&pid_0208&mi_00#6&3b618d17&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global"Since on my setup, the PCTV USB2 2821 Audio filter has the following moniker:"@device:cm:{33D9A762-90C8-11D0-BD43-00A0C911CE86}\PCTV USB2 2821 Audio"... the parsing routine, which relies on the presence of "#", fails miserably.The funny thing is, as I said previously, there is a WDM equivalent for the PCTV USB2 2821 Audio filter. Its moniker is:@device<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />np:\\?\usb#vid_2304&pid_0208&mi_01#6&3b618d17&0&0001#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\waveBut this moniker is not being found by MP. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> Any ideas on the next steps here?</blockquote>
