RSP1A work fine with Soapysdr driver.

Please start:
novasdr-server setup -c ./config/config.json -r ./config/receivers.json
and add new sdrplay device(s)

or copy/paste my receivers.json
{
  "receivers": [
    {
      "id": "rx0",
      "input": {
        "accelerator": "none",
        "audio_compression": "flac",
        "audio_sps": 12000,
        "brightness_offset": -9,
        "defaults": {
          "frequency": 145675000,
          "modulation": "FM"
        },
        "driver": {
          "format": "u8",
          "kind": "stdin"
        },
        "fft_size": 131072,
        "frequency": 145000000,
        "signal": "iq",
        "smeter_offset": -30,
        "sps": 2048000,
        "waterfall_compression": "zstd",
        "waterfall_size": 1024
      },
      "name": "2m"
    },
    {
      "id": "rx1",
      "input": {
        "accelerator": "none",
        "audio_compression": "flac",
        "audio_sps": 12000,
        "brightness_offset": -7,
        "defaults": {
          "frequency": 3675000,
          "modulation": "LSB",
          "ssb_highcut_hz": 2900,
          "ssb_lowcut_hz": 200
        },
        "driver": {
          "antenna": "Fan Dipole",
          "channel": 0,
          "device": "driver=sdrplay, label=SDRplay Dev0 RSP1A 223500B399, serial=223500B399",
          "format": "cs16",
          "kind": "soapysdr"
        },
        "fft_size": 131072,
        "frequency": 7500000,
        "signal": "iq",
        "smeter_offset": -30,
        "sps": 10000000,
        "waterfall_compression": "zstd",
        "waterfall_size": 1024
      },
      "name": "HF"
    }
  ]
}
and then edit with hand.

My startup script for this receivers.json is:
cd ~
/usr/bin/killall novasdr-server
sleep 6
rtl_sdr -g 48  -f 145000000 -s 2048000 - |novasdr-server -c config/config.json -r config/receivers.json

73!
