I have an issue where the audio will randomly stop passing through the O2/SDAC with no indication within Windows that the device is having any issues. Windows Event Viewed doesn't show a disconnect, laptop still thinks it's playing audio through the SDAC, but there is no sound. I have to re-seat the USB cable to bring it back. The issue just started when using this with my new Lenovo laptop/Thunderbolt 4 dock. Worked fine on my older HP laptop and Thunderbolt 4 dock. Makes no sense why the audio would disconnect, but Windows would think the device is still connected. Other audio outputs still work if I switch to them, but switching away and back doesn't recover the connection, only physically disconnecting the cable. This is so frustrating...
