Another method I found is to amend the iidxhock-28.conf
# Force ASIO audio mode/device (if applicable / TDJ default)
asio.force_asio=true
# Force WASAPI audio mode (if applicable / LDJ default)
asio.force_wasapi=false
Then I can use the sound card with output to 24bit/192khz. In the previews version of IIDX, it is not required to change it. It may be caused by updating to Windows 11
