Comment (by Cigaes):

 Please try the following patch:
 Alternatively, you could try to use {{{-filter_complex}}} rather than
 {{{-f lavfi}}}.

 Please also note that, while your command line is, strictly speaking,
 correct, it produces a file with a single-channel audio stream that is not
 declared as "mono" but as "front-left"; this is rather unusual. You can
 fix it using the {{{pan}}} filter: {{{pan=mono:FC=FL}}}.
