PortAudio error when changing sample rate.

[TDW89]

OS: Windows 10
xe file: app_usb_aud_xk_316_mc_2AMi8o10xxsxxx_mix8.xe

error message: ERROR: PortAudio error: Unanticipated host error
the error occurs when going from 176kHz to 48kHz and 192kHz to 44.1kHz

reproduced with the batch file:

@echo off

:: change ADAPTER-ID to match
set ADAPTER-ID=PFFKURWW
set XE=app_usb_aud_xk_316_mc_2AMi8o10xxsxxx_mix8.xe
set XSIG-CONFIG=config_xigRamp.json

xgdb -ex "conn --adapter-id %ADAPTER-ID%" -ex quit

xrun --adapter-id %ADAPTER-ID% %XE%

timeout /t 10

for %%i in (1 2 3 4 5 6 7 8 9 10) do (
    for %%f in (44100 88200 176400 48000 96000 192000) do (
        echo %%f run [%%i of 10]
        xsig %%f 3000 %XSIG-CONFIG%
        echo
        timeout /t 2
    )
)

xgdb -ex "conn --adapter-id %ADAPTER-ID%" -ex quit

{
    "out" : [
        ["zero"],
        ["zero"],
        ["zero"],
        ["zero"],
        ["zero"],
        ["zero"],
        ["zero"],
        ["zero"],
        ["ramp", 7],
        ["ramp", -5]
    ],
    "in" : []
}

Error happens with or without the delays.
Error does not happen if 88200 and 960000 are removed from the loop

unable to reproduce on mac
USB trace shows sample rate set fine but no attempt to start the audio stream

looking at issue PortAudio/portaudio#114 it should be possible to modify portaudio to output more information
