256kbps AAC is their current “high” quality setting.

YouTube Music Premium members can select the bitrate at which music is streamed and downloaded. If you haven’t selected a quality setting, it will automatically be set to the “Normal” bitrate for your

Despite that, many like the service for its wide range of music, much like Spotify aficionados prefer its platform. Good to see WiiM catering for those who some seem to consider the hoi polloi

my ultra here has the only job streaming qobuz and tidal. but i would never have the intention to declare a feature useless because i would not use it.

 

[Ronnie D]

I think it's a plus for those who subscribe to YouTube premium (me) and get YouTube music as part of the package

 

[Smartplug]

If we can get more apps inside wiim like sirius xm and many others.

I do subscribe to YouTube Premium as well, which is why this feature momentarily piqued my interest.

I don't soil my ears with lossy sound, though.

I look forward to seeing what features are available in the WiiM app YTM. My ears are already soil and I wash them properly every day

There doesn’t seem to be anything of interest in this update for me.

YouTube and Sirius xm are my liking. I’m not sure if there’s feature on the horizon you like aside from Dlna.

Since I have YouTube Premium (to not see ads), YTM is a feature I get for free but hardly use. I am interested to see if I will use YTM now that is on the WiiM.

I have given up all hope of DLNA Casting ever working, and it seems like WiiM have too.

Isn’t Dlna supposed to be alternative for airplay especially for their latest devices?

Unfortunately YouTube Music high quality music setting is 256Kbps AAC or OPUS.

You're confused like I was; he's not talking about using DLNA to cast to the WiiM (as endpoint), he's talking about using the WiiM to cast out (as source) over DLNA to something else.

WiiM works fine as a DLNA/UPnP endpoint. I've used this to send audio in high-res lossless from Audirvana on my MacBook Air to my WiiM Ultra.
