Como quiero que el hipervínculo en las citas incluya el nombre del autor y no solo el año, estoy usando, después de la línea que comienza con \hypersetup, el código en esterespuesta. Sin embargo, al hacer esto, aparece el error: Undefined control sequence.

El problema podría estar en esta parte del código:

\xpatchbibmacro{textcite}
    {\printnames{labelname}}
    {\iflinkparens
        {\DeclareFieldAlias{bibhyperref}{default}%
        \global\booltrue{cbx:link}\biblinkstart%
        \printnames{labelname}}
        {\printtext[bibhyperref]{\printnames{labelname}}}}{}{}

Cuando lo elimino, el error desaparece pero no obtengo el resultado deseado de vincular tanto el autor como el año.

Si reemplaza la parte problemática de su código con

\xpatchbibmacro{textcite}
{\printnames{labelname}}
{\printtext[bibhyperref]{\printnames{labelname}}}{}{}

Obtendrá un nombre de autor y un año en los que se puede hacer clic. Sólo no se puede hacer clic en el espacio entre y el paréntesis. ¿Es esto suficiente capacidad de hacer clic?
