latest S2 app wont recognise remote control

I’d guess you’ve never worked with a dev team before. 

Sonos moderators seem to float all concerns / suggestions made in these forums, I would assume in some relatively quickly digestible format. As, I expect, occurs with the Reddit data.

In my past, I had to actively keep devs out of public forums, as they’d both get distracted with invalid data, as well as perception issues about severity and impact of issues. As well as spending too much ‘work’ time consuming the data, rather than fixing the issues. There were others whose job it was to assess and then schedule their efforts. I’d certainly hope that is the way Sonos’ dev teams manage their time. 

Regardless of whether or not your remote works with Android (as the reverse is also prevalent in this community) after a Factory Reset the remote setup must be performed again for the Playbase. 

Also, you should know that iOS and Android can be opposite of each for any given issue. Eight (8) months ago you were praising iOS vs Android in the thread below:

Glad I found this. I use Sonos playbar +sub/surrounds systems in multiple rooms and have always had a swift ir remote setup. Always been impressed by it. 
 

just got a playbase and during setup it just gives me the “We Didn’t Detect Signal…” error using the iOS app (which I was made to update today). Funny enough if it only errors out as soon as I press volume up on my remote. 
 

if anyone has updates on this, I’d be very eager to learn how to resolve this. 

What kind of TV? There have been some folks reporting that Hisense seems to, as near as I can tell, use a ‘rolling code’ which confuses Sonos (I think). In general, re-running the Sonos controller process to register the IR remote works. 
 

TV remotes that use Bluetooth or RF won’t work with the PLAYBASE, but usually the TV’s manual tells you how to set the remote to IR.

For what it’s worth, Sonos stopped making the PLAYBASE in August of 2020, so getting one ‘new’ would be pretty hard. 

This is a TCL tv. Ive used a playbar in this room, it is now in another room with a different tcl tv, and I use these ir remotes in other rooms with my other Sonos systems. 
 

I replaced the playbar with a playbase. When setting up the playbase the app made me update. 

My playbase isn’t new I bought it second hand, but very well taken care of. No signs that it could be a hardware issue due to miss-handling. I’ve bought plenty of second hand Sonos products with 100% success so far. I’m really hoping this is a software issue. 
 

what’s most peculiar is that I get the error as soon as I click the volume up button on my ir remote as instructed in the setup wizard. Another reason why it feels like a software glitch.  

Might help, might not, to know for sure if you’re using S1 or S2, but then it shouldn’t really make a difference. I’m assuming you’ve tried resetting the IR on the TV’s remote, and reset up the IR recognition in the Sonos controller?

I’d probably call Sonos Support to discuss it.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

You may want to search these forums for particular issues with TCL TVs as well, if I remember correctly, they’ve come up before with issues. 

I can confirm it is indeed an app software glitch. 
 

luckily my wife’s iPhone still hadn’t updated the app as mine had been after being prompted during setup. 
 

while on my phone, app updated today, it kept telling me the ir remote wasn’t recognized, on my wife’s phone it got a similar “didn’t recognize” message but proceeded to ask me to click volume up 3x, then volume down 3x, and lastly mute 3x. And now it works. I remember having to do this in the past during previous installs of my play bars. 
 

hopefully this is just an app issue that they’ll solve soon otherwise I’ll have to make sure at least one of us holds out using the old app as long as possible. 

I’m not familiar with the TCL IR commands, but some remotes send different Volume commands depending on how long you hold the button. This can make teaching a command to SONOS tricky. If you press the IR button quickly a single command will be sent, while press and hold may send a string of different commands, possibly not ending until the button is released. Another type of command is not correctly learned unless you hold the button until SONOS acknowledges that the command is learned. The Android or iOS device is only involved while you are teaching the soundbar IR commands. Once the IR Volume commands are learned, the IR remote can be used for soundbar TV Volume adjustments while the Android and iOS devices are powered down.
