I'm looking to get OpenWebRX running on my RSPDuo connected to a RPI5 running the latest Debian. Currently getting SoapySDR to talk to the hardware via the sdrplay_apiService "driver" but the apiService doesn't actually reach the point of listening for TCP connections.

root@raspberrypi:~# systemctl status sdrplay
● sdrplay.service - SDRplay API Service

I've straced the process and just get a lot of

futex(0x7fae6d2058, FUTEX_WAIT_BITSET|FUTEX_CLOCK_REALTIME, 0, {tv_sec=1741893489, tv_nsec=743687000}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
futex(0x7fae6d2000, FUTEX_WAKE, 1)      = 0
futex(0x7fae6d2058, FUTEX_WAIT_BITSET|FUTEX_CLOCK_REALTIME, 0, {tv_sec=1741893489, tv_nsec=753687000}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)

futex(0x7fae6d2000, FUTEX_WAKE, 1)      = 0

Anyone using the SDRPlay API successfully on recent debians? Anyone know how to debug sdrplay_apiService?
