This system is in my restaurant and has been working for 2+ years so I know the usual tricks but now it will not play any sound. It's connected but no sound. Tried in 2 different places with different speakers and same problem. Did factory reset also. Speaker appears connected I don't understand! Ah 🙂
Thank you for your post and welcome to the Bose Community.
I'm truly sorry that you are having some difficulty playing audio from your SA-5 amplifier.
Are you able to play audio through Bluetooth at all or the AUX connection?
I'd also recommend checking for updates for the SA-5. You can do this by visiting this article. Manually updating your SoundTouch system.
Let me know how you get on with this.

It's hooked up to an iPad and the app is up to date - I even erased and reinstalled the app. I tried Bluetooth hooked up to my phone and same thing no volume - today I will try aux. And the manual update you referenced using a computer
Hi - did an update via the app so it is up to date - still no sound - tried with aux cable and it sounds like fuzzy crackly static noise coming from the speaker
Thanks for getting back in touch.
Have you tried checking the speaker wire to ensure this is not damaged? If you try using different speaker wire and the issue persists, I'd encourage you to reach out to local support to discuss your options for service. Details can be found here.
Hi yes a different amp has no problems so it's not the speakers - I had to buy a new one in the meanwhile but a little disappointed since I've only had it 2 years or so - ok I'll check out that link

I’m Having the Same Problem, the receiver is connected but Does not makes a sound, I checked for updates and the system is updated. It looks like the output is not working. What do I do next?
I'm sorry to hear you're also experiencing an issue with audio output on your SA-5. Have you checked all wiring to ensure it's securely connected and nothing is damaged? Have you attempted a product by disconnecting the amplifier from power for two minutes?
Are you having issues playing music through both the SoundTouch app and when connected to a device via Bluetooth?

Now is the end of 2020, and I have the same situation. The SA-5 amplifier worked well, but now it does not work. He controls through the program, turns on the broadcast, but there is no sound, as if the sound reinforcement stage has burned out. What a blessing that I have in stock another such amplifier! The speakers work with him. But what happened? I discovered the following strange phenomenon: if you try to connect the connector to the AUX1 input (just touch the AUX1 connector with the source cable), the broadcast sound disappears! I disconnect the AUX1 connector and wait ... after about 15-20 seconds, the broadcast sound smoothly reappears. Once again I touch the AUX1 connector (L or R is indifferent) - the sound immediately disappears again. If I connect the signal source to AUX1 and don't turn it off, the sound does not appear on the broadcast either on AUX or on Bluetooth. Only complete disconnection of the AUX1 input allows the amplifier to work. In order not to think about the malfunction of the sound source, I connected him to AUX2 - everything works fine here, both broadcast and AUX. There seems to be some kind of bug in the firmware? Perhaps AUX1 is selected as a priority input, which turns off any other sounds, as a result of this, any connection to AUX1 turns off all sounds and does not work itself. This is true?
Unfortunately, the first amplifier stood with the connected AUX1 input for two weeks. And, although these two weeks he was not used, but such a connection on AUX1 seems to have caused him irreparable damage. In any case, it doesn't work at all now. Tomorrow I will try to reboot it and cancel all settings.
I am interested in the opinion of a BOSE technical specialist on this issue. Why do two amplifiers from the same batch react this way when connected to any of the AUX1 (L-R) connectors?
Sorry for my awful English, hoping for help, Valentin (mr.)
