HifiberryOS and DAC+DSP

Hi, I have installed HifiBerryOS and am currently trying to use the DSPToolkit to load some REW filters to the DSP.  Every Dsptoolkit command I try gives the error shown below -

# dsptoolkit get-volume
Traceback (most recent call last):
File "/usr/bin/dsptoolkit", line 7, in <module>
File "usr/lib/python3.6/site-packages/hifiberrydsp/dsptoolkit.py", line 829, in main
File "usr/lib/python3.6/site-packages/hifiberrydsp/dsptoolkit.py", line 414, in cmd_get_volume
File "usr/lib/python3.6/site-packages/hifiberrydsp/dsptoolkit.py", line 145, in get_volume
File "usr/lib/python3.6/site-packages/hifiberrydsp/client/sigmatcp.py", line 258, in request_metadata
IndexError: index out of range

Any ideas? The DAC works perfectly with Volumio so I don't think there's a problem with the board.
