[hpsdr] No RX audio with Thetis

[N2CBU]

Win-10 Pro; no RX audio with THETIS v2.6.9 and ANAN-200D; seems as if, maybe, the sound card isn't being found?
Windows system sounds, music, audio from videos, etcetera, are all perfect. Oddly, I had the same problem with
OpenHPSDR mRX PS before upgrading firmware to Protocol-2 (v1.8). Otherwise, all radio functions seem to work, just no
sound from the computer speakers. Simon Brown's SDR-Console (v3.0.22) works perfectly though, so...???

Any ideas? Thanks!
