DAX sound devices are NOT loaded

edited November 2021 in SmartSDR for Windows

I replaced the motherboard on my w10 computer. The hard drive was an MBR type and it would only boot with a video card installed. SmartSDR was working. Using mbr2gpt I changed the drive to a UEFI/GPT boot. It allowed me to remove the video card and run the on-board video. That's when SmartSDR stopped working. In device manager, I was seeing "!" on the DAX sound devices. I shutdown SmartSDR, turned off the 6600 and removed all flex software.

After rebooting a few times I reinstalled SmartSDR. Now there are no DAX sound devices in device manager or the Sounds window. I get DAX errors on all sound channels.

    Hi Jack, It sounds like you need to submit a help desk ticket.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
