What bitrate does the Chromecast Audio stream at?
There have been other threads addressing this problem, but they all seem to give contradictory answers.
This thread says that the Chromecast automatically streams at 320 kbps:
This thread says that the audio quality is determined by the streaming source (i.e., the Spotify app):
This thread leaves both answers open as options:
Finally, this thread says that the option to change the sound quality of the Chromecast has been implemented within the Spotify app settings, which doesn't seem to be correct:
Can someone with definitive knowledge of Spotify's integration with Chromecast Audio (i.e., a Spotify employee) give an answer?
Solved! Go to Solution.
I opened a supoprt ticket with Spotify today and they confirmed it's not possible to stream to the chromecast at 320Kbit/s currently, but he said;
"our engineers are currently working on getting the streaming quality higher."
He also confirmed premium users currently stream to chromecast at 256kbit/s.
I'm going to try out Deezer tonight and see if the sound quality is better than Spotify, can't find a clear answer on their website either as to what kbit/s they stream. Wondering if it's a limitation of the chromecast audio rather than Spotify.
Unfortunately, nowadays any normal computer software is called "app", not only those programlets you load onto your smartphone. So in this case, no smartphone, only laptop.
To clarify: chromecast <--(160 kbit)-- laptop <--(400 kbit)-- spotify-server
As I wrote I doubt, but I am not quite sure, that chromecast has a direct link to the spotify-server. But in this case, only a flow of control data from laptop to chromecast would be necessary with 10 kbit or so at most.
So my hypothesis is, that spotify just sends a default 128 kbit stream to chromecast no matter what.
