ZeroDivisionError: division by zero
golledgekb opened this issue · 2 comments
Running into a divide-by-zero error. I have run through multiple manual and auto script installs in addition to the provided preconfigured image with no luck. Any suggestions?

Hello [golledgekb]
I had this kind of problem on many PC i've tried. Now i run a Intel Nuc I3, without issue.
Probably an hardware/driver incompatibility ...
Good luck !

What computing hardware, power supply and USB cable quality/length? This error simply indicates that the DSP code received no data, and the most usual cause of this is because the tuners did not all start up due to some problem with the power supply being insufficient, or poor quality cables.
