SACD iso and DSD noise when stopping or closing music player

I've had this issue with two DACS and ASIO playback of DSD files (SMSL SU-9 and my current Gustard x26 Pro). When I stop playback or close Jriver/Foobar, I get a pretty loud indescribable noise out of both of my speakers. I have to turn off the DAC to stop it. I can resolve this by sending DSD via DOP, but I would like to think there is a solution to this issue. I've tried different USB cables, PCIE cards, etc. and nothing clears this up. Any suggestions will be appreciated.

Windows 11 / JRiver or Foobar / ASIO-USB / Gustard x26 Pro / AVA Vision SET 120 power amplifier / Elac Carina speakers
