Thank you for the post. There is no new update on this. The SoundTouch 300 will still shut off after 2 hours of inactivity if not connected to a network (either Wi-Fi or Ethernet) and the Bluetooth pairing list is empty. If we hear of any new information, we will let he community know.

So, I have the same problem. Is it possible that Bose has not solved this common problem after several MONTHS of people posting about it? C'mon. With the Soundtouch 300 and the bass module, it's like a $1600 TV speaker that only works for two hours at a time. Who would knowingly pay for that? I'd really like to NOT have my TV sound cut out right in the middle of something every single night. I don't hear people complaining about Sonos systems doing this.

So here I am - yet ANOTHER unhappy customer experiencing the same problem. Do I need to take this thing back and give up on BOSE forever? The only way I can get sound at all is to have both the HDMI ARC and the optical connected. This makes NO SENSE! And then yes...after 2 hours boom - off goes the sound. I was THIS close to purchasing the subwoofer and surround speakers but, if this is any indication of what I can expect, I doubt I'll invest any more money not knowing if they'll even work! Would someone PLEASE give us a DEFINITE ANSWER on how to fix this problem once and for all? It's obviously gone on for entirely TOO LONG!

I have CEC set to Alternate On which resplved the issue of the Soundtouch 300 turning off after 2 hours. Initially I had issues with the TV and Soundtocuh staying connected. Take a look at this thread wshere I posted how I got it to work.
