Deltacast card not seen at startup/wakeup with macOS Sonoma (or later) and Deltacast Drivers 6.25.1 (or earlier)

We have had reports of Deltacast cards that were sometimes not seen after your Mac has started, or after waking up from sleep. The issue is caused by a change in Sonoma's boot sequence that put the PCIe enumeration in the wrong order for the card to be properly detected.

Deltacast has provided a fix for the issue when the computer starts. It is available in Drivers 6.25.3 or later, that you can download from this page.

Currently there is no fix for the issue when the computer goes to sleep and is waken up. The card will remain unusable until you restart your computer. The current workaround is to prevent your computer to go to sleep. We'll post here as soon as Deltacast has provided us a version that fixes that issue too.
