Deezer HiFi icon disappears when I stream to Chromecast Audio

Bonsoir ,

en effet je n'ai pas fais le test.

Je prendrai le temps de faire un test de comparaison avec Tidal , car je trouve que le son de Tidal me semble bien meilleur ...

Ce serait grave quand même !!! 😅

Okay, I just tried to monitor data traffic directly from the router. But I am not a real technical person. I cannot make a definitive conclusion.there are better results now,  Like 75 megabytes for 3 songs. So that really seems like FLAC quality to me. reading this from the router doesn't allow me to completely rule out other devices at home. But other connected devices should not consume much data.

Now thats good news!!!

3 years later, an app redesign, and still haven't fixed this. 

For those landing here in 2024, I saw @Barendrecht post and went into my router as well.

I looked at the real-time traffic and when a new track starts, inbound WAN (Internet) Traffic shows around 15-30MB depending on the the song. 

I'm not satisfied with that. 

Next I look at real-time bandwidth monitor for individual devices. The device that's receiving the castig is getting around a 30-50Mb blip. Great right? NO IT'S NOT.

Mb is Megabit and MB is Megabyte. 30Mb is 3MB. A lossless file is the 15MB-30MB just like the incoming traffic at the beginning. This means it's either compressed and/or not HiFi. 

To validate this, I set quality to basic everywhere just to be sure. Download was 3-7MB in Router data. Going back to traffic monitor, the casting receiver is only pulling a blip of 13Mb now. That is now a 1.6MB file! 

What does this mean?

It means is Deezer is requesting a HiFi track but only casting a Standard file and probably compressing it. 

CASTING IS NOT LOSSLESS.

​​​​

Update to above. 

I further validated this. Discovered my AVR (same device used for casting) has Deezer built in.

Started a song. Plays FLAC at full 44.1kHz/16bit per the interface. 

Went into router again to monitor and data amount is inbound again for a full FLAC quality file. It's transferring to my AVR at an average of 1Mb per second.

The track is 4:11 minutes long. 4:11 minutes in second is 251 seconds. As mentioned above it was at a rate of 1Mb per second so my AVR received 251Mb of data.

251Megabits is 31.37 Megabytes. A FULL FLAC FILE.

This settles it for me. Casting is not FLAC. 

@SyCoREAPER just tested this too and definitely get the same results.

I have a second router with nothing connected to it so I can isolate traffic to playing from Deezer, I setup bandwidth monitoring and tested HIFI through the phone connected to this network.

The songs played at HIFI around 50 MB a song (not Mb)

I then sent to chromecast on my google TV connected to this network. The HIFI labelled disappeared from phone but crucially it does show it on the TV. However it was not playing HIFI, playing 320Kbps I believe

You can see on the second chart it’s just one or two lines, approx 10 MB a song which is what you would expect from 320Kbps.

It’s a bit of a shame because I listen to majority of my music via chromecasts and wanted HIFI for that. Specifically I have a chromecast audio connected to a HIFI where I wanted to benefit from the superior sound. 

I then thought it might just be a limitation of chromecast for certain devices as the chromecast audio offers a setting for “Full Dynamic Range”. I guess this compression happens device side rather than requesting a lower quality version but to check I tested playing  HIFI on chromecast audio but the result was the same.

Tbh because of the google compression I think it doesn’t matter for most CC devices if HIFI works or it gets the high quality but for people who are using devices that offer Full Dynamic Range, it would be good to have this feature working.

I might see if I can debug the chromecast device and get the actually audio link and see if there is anything evident in there for what is being sent. Feels like deezer is just passing the wrong file URLs to chromecast

@dteezle 

It's definitely not a hardware limitation. Chromecast can receive ATMOS tracks which are way bigger. Additionally, as mentioned, my AVR was what tipped me off to the low-quality. If it can't cast tomthat properly, it means something is broken with Deezer. 

I doubt this will ever get fixed (other than if they are reading this to contradict me) since they erroneously said its fine and haven't addressed it since. 

For the past few days, the HiFi/Lossless badge no longer appears in the Deezer Android app when casting to my Sony Bravia KDL-55 TV (Google Cast built-in).

Details:

Device: Android phone

TV: Sony Bravia KDL-55

Plan: Deezer Premium/HiFi

Streaming & Google Cast quality both set to High Fidelity

HiFi badge shows normally during local playback

As soon as casting starts, the badge disappears

No quality indication appears on the TV either

I’ve already tried:

Restarting the app and phone

Clearing cache

Restarting cast session

Toggling HiFi settings

Checking TV firmware

The issue happens every time and started only recently, which suggests a bug after a recent app or casting update.

Perhaps, HiFi is still streaming during casting, even if the badge is missing but the impact is as follows,

Impact

• Users cannot verify whether they are receiving the audio quality they pay for.

• Loss of trust in Deezer HiFi features when casting to Google Cast‑enabled devices.

• Negative user experience for HiFi subscribers who primarily listen through smart TVs.

A fix is being worked on?

Thanks!

Hi ​@DJ_scorman the problem has been fixed and you should be able to see the HiFi logo on Chromecast now.
As for TV’s, the problem has been reported and should be also fixed soon.
Thanks for your patience
