I have the following problem with my Marshall Stanmore (I) Bluetooth speaker:
Whenever I am wirelessly connected, the Bluetooth connection drops after 20 minutes — while playing music!
The surprising thing is that it not just happens randomly after 15 to 45 minutes — no, it happens suspiciously regularly after 20 minutes. I went and tested this with my laptop (4 times) and my phone (3 times) by writing down the start and stopping times, and the Bluetooth connection got interrupted (the music stopped) after 20 minutes each time. 7 times in a row. No exception.
• Yes, I have removed the speaker from all devices, then re-repaired them. Multiple times.
• Yes, the problem exists with all my devices that can send sound via Bluetooth (laptop, phone, desktop,). Those same devices have no problem to stream music to my Sony sound system or portable Bluetooth speakers. The problem only exists with the Stanmore.
• No, the Stanmore is not near a wifi router, a micro wave, a DECT phone or close to other Bluetooth devices. All of my other Bluetooth devices work perfectly fine. During my tests, the speaker and the Bluetooth source were about half a meter/two feet apart.
• Yes, I have had the Stanmore disconnected from power for an hour. Even a few days, actually.
• Yes, sound works perfectly fine via the wired connection (INPUT 1) and it doesn't stop after 20 minutes.
• Yes, the "STANDBY MODE" switch on the back is set to "STANDARD". (But surely no Bluetooth speaker would ever go into standby mode WHILE playing music anyways, right?)
• No, I am out unfortunately of warranty. The speaker looks great and hasn't been used that much. I also find that it financially doesn't make much sense to spend 130€ (max.) on a Marshall OOW repair.
• No, the Stanmore I is not compatible with the Marshall Bluetooth app, and there is no way for me to update the firmware (as far as I know).
• Yes, I can absolutely open up the speaker and post pictures of specific components, if someone has a clue about what capacitors or chips to look out for.
Additional info on the issue:
I experience no problems connecting via Bluetooth, from any device. I can start playing music — but after 20 minutes, the music will automatically stop. If I am streaming from Spotify for example, the player will just pause. The Stanmore stays powered, and the red BLUETOOTH light on the Stanmore is still on, but it appears a little dimmer than normally. I have found that pressing the SOURCE/WAKE button once usually wakes up the Bluetooth connection again, and then after a while, I can resume music by un-pausing on the laptop or phone.
The fact that this happens after a very precise operating time, sure sounds a lot like it could be standby-related. But the Stanmore is not set to POWERSAVER mode. And even if it was, it would only enter standby mode after a certain time if it wasn't playing anything. A speaker that goes into standby mode every 20 minutes WHILE playing music ... that would be ridiculous! And yet, that is exactly what I am dealing with.
Any ideas or clues for what to try or look out for?

It's funny, Marshall create a forum to answer all questions inviting you to send an email.
So I have the Stanmore 2 Smart Alexa speaker and there is no way to remove this feature. Basically goes to standby every 20 minutes.
Can anyone help here?? I too have the exact same problem with my Acton Voice II (for Alexa). Music suddenly cuts off after exactly 20 minutes.
Contacted customer support but I was basically told off because I don't have a purchase receipt, although I explained I received this as a gift last Christmas. They still won't budge, nor make any attemps resolving the issue. This is beyond disappointing!
Me too, i had this problem too. my device is marshall action 2 voice alexa.
It's been 2 years. Can someone provide any workaround? Can Marshall please update the firmware and make the auto standby mode optional?
