I am sorry to hear you are having trouble with your SoundTouch 300.
Regarding the lack of SoundTouch 300 support on our website, we have recently started shifting the SoundTouch.com content to the Bose.com website, and therefore, some products such as the SoundTouch 300 are still missing. To find information regarding the SoundTouch 300, please use this link.
Does this issue happen regardless of the source or source device you are using?
As you are not willing to try a basic reset (unplugging the soundbar for 30 seconds after having turned it OFF, and once reconnected giving it 30 seconds to reboot), a factory reset could help. However, please be advised that this will restaure the soundbar to factory defaults and erase ADAPTiQ settings.
If this does not help, the best course of action would be to reach out to our customer support line in your country of residence and get your soundbar repaired.

Hi Kazafog and Geoff potter,
I'm sorry to hear that you're having issues. The order in which you turn on your devices can impact if the TV and soundbar will make the proper connection. One of our users posted about this HERE with his KS8000. Please let us know if these steps resolve it for you.

I just updated my soundtouch 300 to SoundTouch 17.x (https://community.bose.com/t5/SoundTouch-Speakers/SoundTouch-Ecosystem-Update-Available-November-28t...) and I am having a ton of ARC issues.. It works for a few mintues, and after tv on/off it doesnt work. Samsung TV with Apple TV connected to it. It use to work perfectly fine before update.
Also tried hard resetting my TV and soundbar 300. Still having trouble connecting via ARC. Is there a way to revert the update?

Sorry to hear that you are experiencing a similar issue. Due to compatibility issues that may arise, we do not recommend or provide roll-backs to older software versions. Curiously, have you tried the reset steps in the order that Brent provided above?
Geoff, what did you decide to do? I purchased the ST300 and cancelled my order after reading of all the issues with Samsung TV's ARC connection. I can't believe Bose has allowed this to continue for over a year with no fix...absolutely unacceptable. I have held off on purchasing the Sonos, because I want to retain the TV control through my Samsung Smart Remote and Sonos doesn't offer ARC connection at all. Just curious what you decided to do?
Geoff, do a quick Google search and you will see that Bose ARC connection has serious issues. If the ARC connection is working properly then the Samsung remote would work to control the volume and such. However, Bose can't seem to get their stuff together regarding this issue. It's been an issue for over a year that Bose can't seem to resolve.
In other words, you should be able to easily use your Samsung remote to control your Bose volume, but Bose ARC channel does not function properly. They have know about this for over a year and have not provided a fix. If you want to hold out and hope for a fix, that's up to you. I cancelled my order for the ST300, because I want to retain the use of my Samsung Smart Remote and from what I've read online, the ST300 has been nothing but a problem for people using the ARC connection. Even Bose tech support told me to rethink my decision to purchase based on the problems the ST300 has with Samsung TVs. I'm completely understanding of having issues and providing Firmware fixes, but it's been over a year and Bose can't seem to get it together. From what I've read the latest Bose Firmware upgrade made matters even worse.
Just as an example I currently have a Yamaha 207 which I wanted to upgrade to the ST300 for sound purposes, but it has worked flawlessly since the moment I hooked it up via ARC to my Samsung Q7F. I mean flawlessly, no lost connections, no sound issues, no sound dropping, etc. My Samsung remote has worked perfectly since day one. Maybe Bose should consult with Yamaha regarding how to ensure a properly functioning ARC connection. I really have my head set on buying the ST300, but I refuse to until they fix the ARC issues for good.
