Can I somehow add the audio device name

I don't think there is any easy way to do it without applying some card_mod. Looking at some of the examples that I played with, you can modify the primary and secondary values.

type: vertical-stack
title: Tile card (card_mod)
cards:
  - type: tile
    entity: light.bedroom_lights
    card_mod:
      style:
        ha-tile-info$: |
          .primary {
            font-size: 8px !important;
          }
          .secondary {
             visibility: hidden;
           }
           .secondary:before {
             visibility: visible;
             content: "{{ states(config.entity) | title }}";
             font-size: 12px !important;
           }
        .: |
          ha-card {
            font-family: arial;
            padding: 15px 15px 15px 15px;
          }```
