Not really, but a couple of random questions that may<br>
lead to better guesses (or additional confusion)<br>
<br>
* Is your MythTV BE in a VM too?<br>
<br></blockquote><div>No, the BE is on the host, which is ubuntu 22.04, and BE is the latest V32.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
* Have you validated it is IOMMU by disabling the enablement?<br></blockquote><div>Yes, I backed out of the change last night and the BE worked for all my prime time recordings. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
* What is your distro/version?<br></blockquote><div><br></div><div>Ubuntu 22.04, 5.15.0-58-generic </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
* Are you using in-kernel drivers, or the Hauppauge PPA drivers?<br></blockquote><div><br></div><div>Pretty sure I'm just using in-kernel drivers... </div><div><br></div><div>I don't know much about iommu groups, but I am wondering if each half of the tuner is being put into separate iommu groups and hence it breaks the driver? There was a little script I ran after enabling iommu that shows what devices are in what iommu groups, and this card looks like two Conextent devices, and they are put into separate iommu groups. I can't reproduce that output because I backed out of that change and it's currently working without iommu being enabled.</div><div><br></div><div>Thanks,</div><div><br></div><div>George</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
