A caveat with that though - it doesn’t support gapless AMHD playback, guess we’ll have to wait a couple of months for that…The quality is dictated by what the target device I.e. the WiiM, supports. So, for example, if I ask “Alexa, play Mr Blue Sky by ELO on Puck”, it plays at 24/192 on my WiiM Mini.
Edit: To more directly answer your query, that also works where you have the WiiM defined as preferred speaker in an Alexa smart home device group along with an Echo. Just tested that to be double sure![]()
