The sound generally lacks treble, but the when it cuts in it fades the sound down over about 1 second, then fades up over the same length of time returning with full rich sound that I would expect, but this only lasts a few seconds then it fades to mute and returns with dull sound once again. It has done this in two different install locations and the wiring looks intact. I just cant see any other solution than something software based?
Try the following:
1) Switch the unit off completely, using the powerswitch on the back of the bass box.
2) Switch the unit back on via de switch on the bass box.
3) The display should read BOSE 321 and than be dark.
4) Insert a CD and switch the unit on with the remote by selecting the CD/DVD mode.
5) When the sound is now OK, it means that you need to contact Bose to ask them for the latest software update for your unit. After updating your system. The problem will not reoccur.
6) in case the problem continues and at start-up using a CD, no improvement of sound is heard, the system should go into repair. Contact Bose in your country and ask for return instructions.

SOURCE: BOSE LIFE STYLE SYSTEM SOUND (AUDIO) GOES QUITE FOR A SECOND
This was posted a while ago, so I'm sure it's probably been solved by now.
For anyone with audio issues using this or any other Lifestyle system:
If you experience audio problems (no audio, intermittent audio) from more than just 1 source (especially if it involves internal sources like DVDs or the radio) then just reset this by unplugging the power for about 30+ seconds from the bass module and the media center DC power. Check the audio input cable (multi-pin din going from the media center to the bass module) for bent pins.
If this doesn't solve the problem, you could try replacing the input cable, but those are usually pretty robust. You could call Bose at 800-367-4008 for tech support or to set up a repair if this fails.

The sound and picture synchronization are adjustable in the system menu. Refer to your owner manual. If unavailable you can find the manual at Bose.com.
Sorry can't be more specific at the moment, don't have manual handy.

Well, it seems that this may be a common issue with this BOSE unit. My 321 GSIII was working fine as well for about a week. After a full frustrating day of switching, disconnecting, reconnecting cables and resetting the unit and TV several times, I was forced to call the BOSE Technical. They tried to help with the situation over the phone by directing me to do just about everything I did before I ever called them. After about an hour of their unsuccessful help, they left me in saying that I will now have to run Composite cables because my TV will not connect for some reason through HDMI even though it was working for a short time. AHHHHH...I custom prepared the walls in my new office to accommodate non-exposed cables and wires and now BOSE is saying to expose Composite cables. Tomorrow, I am going to connect the Composite cables to confirm if the 321 will now work that way (for curiousty). I will then call BOSE back and demand a replacement unit. I will keep all in the loop with my progress of this situation.

I now have this same problem. Would like to know if there is a fix or if my system is just failing for good
