Show stars in excerpts

I am testing YASR and am very fond of it.
I would like to put my post ratings in the excerpt text. However, the excerpt display does not show the stars. Obviously the shortcodes are stripped from the excerpt.

I Googled the case and found s=the tip to add this code to the theme’s functions.php:

add_filter( 'the_excerpt', 'shortcode_unautop');
add_filter( 'the_excerpt', 'do_shortcode');
add_filter( 'get_the_excerpt', 'do_shortcode', 5 );

That does not work at all.

Then I found this plugin: https://www.ads-software.com/plugins/shortcodes-anywhere/
That works only half way. The prefix text is shown but not the stars.

How can I get the YASR stars shown in excerpts?

Best regards,
George
