Roam not connecting properly, faint and stuttery.

A flashing orange and white status light could indicate a fault condition. I would contact Sonos Support:

I’ll have to do that, it’s just odd that I can get a solid white light until I try to play music, then it faults out. 

Also, finally (randomly,) got the Bluetooth to connect again, and it goes from solid blue when connected, to blue and red, then orange, back and forth as the music stutters through.

Sounds like the device might be in diagnostic mode, where the ‘play/pause’ and ‘volume down’ buttons are pressed/held together for about 10 seconds -  A reboot should revert it back to normal mode.

Maybe just try holding the power button down for about 15+ seconds (whilst off its charger) till the Roam reboots/resets and see if that fixes it - if not I would speak with Sonos Support, as mentioned earlier.

I tried that (I saw your an earlier post of yours,) and neither the play and volume down, or the factory reset helped.

I appreciate the suggestions, and will get in touch with Sonos.

Aaaaaargh, I am having *exactly* the same issues. 
I was given a Roam as a christmas present and it’s driving me mental. I’ve not had a day yet where it’s worked properly. 
Today was my best day. I finally managed to get it to run off the WiFi, my AppleMusic was running and Alexa was even playing stuff on demand. It was perfect! 😍
 

Suddenly, I opened my laptop to do something completely unrelated (using WiFi), and my Roam just died. Back to stuttering when Alexa is speaking, and when music is trying to play, and the light above the Sonas sign slowly flashing orange and white. Even powering up and down, it’s not making any chimes. Now I cannot get it to connect at all. 
 

Is it meant to be this complicated? 

A flashing Amber/White status light can sometimes mean your device is possibly trying to install an update - maybe power off the device fully and then return the item to its charger, let it boot up and check for any updates via the Sonos App.

In rare cases, a flashing orange and white status light can also indicate a fault condition and if the problem persists, I would perhaps submit a Sonos system diagnostic report and post its reference back here and then chat/contact Sonos Customer Care.

What’s funny, is that everything that people have suggested has worked, but only briefly. The second the Roam is turned off or paused, it goes back to the “fault state” and the “fix” may or may not work again.

Im in the same boat, In general my roam is working, but it seems much more picky and complicated than a portable speaker should be. I’m having the same problem with the stuttering/hiccupping sound, and trouble connecting to bluetooth. Bluetooth I got to work better after making my phone forget the device, and reconnecting.

Regarding the problem you are having, I just finished resetting the device and trying it on another network. After “successful” set up I was getting music on 2 other sonos speakers, but the roam was flickering and flashing the orange light, then after a minute or two, it started working, I’m wondering if this is the truetune setting up. I know this sounds like stupid advice, but maybe give it 5 minutes?

I thought it might be True Tune as well, so I tried it with True Tune on, and also disabled and didn’t have any better luck. I may try it again, giving it more time (as you suggest,) just to have that bit of trouble shooting out of the way, but if that’s going to be the issue over and over, the Roam is basically going to be useless to me.
