These types of questions better to ask in the main card-mod thread instead of creating a new 1000th thread.
Why using mod-card? Not needed for a stock media-player.
A keyword “card_mod” is missing.
Variables can only be used here if this media-player card is a custom field inside button card.
Apologies for not putting in the correct space. Sometimes we don’t know what we don’t know.
This is actually in a button card. I guess I should have shared everything. Since I have found I can get rid of the name by setting it to a string with a space in it but that speaker image still remains:
Find out how to style a particular element of media player card - which is a standalone card, not a part of button card. Go to card-mod thread for details. Btw this thread has a dedicated post for media-player (which may not contain styles you are looking for - but may give you ideas).
Then find out how to apply same style inside button card.
