Spotify - Beware!!

[zee9]

Hello everybody,

Most of my streaming is done via Qobuz, Spotify and my saved music collection. Spotify is obviously the easiest to use and is perfect for guests to play tracks when they visit home.

For the past week there has been a major issue with Spotify and my Adsm. Please be careful when trying this as when you chose the linn device via Spotify my Adsm switches on but at an extremely high volume. Don’t know how risky this is for my integrated akubariks but it scared all my neighbors at 6am when I tried to play some music via Spotify.

The linn engineers are aware of this issue and apparently one other user has made the same complaint.

Earlier if you adjusted volume (via the phones side buttons). while the Spotify app was open it changed in increments of +/-1db and +/-3db if you were on the home screen.

Now no matter what screen you’re on its +/-3db for the first three clicks and then 4db and then repeats the same pattern. This is not a scarey issue but when my Adsm is in standby and if I chose to send Spotify audio from the Spotify app to the Adsm it starts at a ridiculously loud volume. My guess is 65/70 even though my start up volume is set to 40.

PLEASE BE CAREFUL USING SPOTIFY WHILW THE LINN ENGINEERS FIGURE OUT WHAT THE ISSUE IS.

Please note I just tried another test after switching off the Adsm via the button. The volume shoots up to the max set volume of 65 which is what I’ve set as the max volume on my Adsm.

Thanks for the Heads Up @zee9. @Nestor Turton also raised this in this thread https://www.hifiwigwam.com/forum/threads/lejonklou-kalla.106554/

Here’s another thing that I’ve found and I think this is the main cause. This glitch only happens with my and my wife’s iPhone and both happen to be on ios16. When I attempt it with my iPad (ipados15.x) there is no issue with the volume.

I also tried using a web browser on my phone to access Spotify (not the app) and the volume worked fine.

I’m guessing this is a Spotify issue with ios16 devices but this glitch only happens with linn as the endpoint. Not other devices like echo dot etc

So it’s somewhere between linn, Spotify and ios16

Not quite the same issue but I’ve experienced that my neighbors (?) started to play Spotify on my ADSM (not my taste of music). It ended up in me whitelisting all allowed equipment in my router and for the first time limiting the volume in the system.

Yup, that's the worst thing about spotify connect. Only way to fix is to factory reset your DSM to break the connection. I never allow guests to connect to my home network anymore al because of Spotify. They can only join my guest network, so if they want to control the music they have to use my devices and not theirs.

I block 78.31.8.0/22 (Spotify servers) and 193.182.8.0/21, 193.235.232.0/24 and 194.68.28.0/22 (Spotify mobile).

If anybody knows any other Spotify addresses I should block then please let me know.

Please excuse my ignorance, but doesn't that imply that your neighbors' devices were inside your wifi? That part I am not quite getting yet: ok, any device on your lan/wifi can send spotify to your Linn. But how does this work from outside your LAN? An xDSM isn't usually reachable from the outside internet, so how does an outsider access it?

Are you blocking inbound traffic from these servers? How would they reach the DS, which is behind NAT, presumably, anyway? Or is it that the DS regularly polls spotify on these addresses to find out if somebody designated some tracks for it to play? Please excuse my ignorance, not a streaming service user myself.

I think it works the other way round. The Spotify connect part of the DSM is checking if Spotify has music to play. If it has, it plays.
Something like that.

I believe Spotify have greatly reduced the chance of previously connected controllers playing music to your DS (or any other remote devices). As of a change from about 1 month ago, it appears that previously connected controllers are 'forgotten' after approx 30mins, hence after this time interval, only locally connected controllers can connect to the DS.

Previously any controller which had been connected to a DS would 'remember' that connection and be able to send audio to it remotely for a much longer time period (in the order of days).

Note that for the initial connection to the DS, the controller must have been on the same network as the DS, hence the neighbour above must have been connected to the owners network at some point in the past - presumably this was authorised - if not it is time to change the wifi password

Outbound access so nobody can establish a Spotify connection from my home network. I'm unsure of the details of how Spotify works, but my thoughts are blocking access to every address in the ranges it owns will help keep it away from my cottage.

I had hoped blocking port 4070 would do the trick, but I'm told Spotify looks to use other ports such as 80 if its own port is blocked.

You are right that Spotify cannot connect inbound to my home network, which NAT'd behind a firewall, unless there is an established outbound connection.
