Unless there's some kind of pre-amp volume control on the unit it sounds like the main amp is faulty. It's clearly something common to all channels. However this could be down to that the main power amp is a single IC for both channels.
Testimonial: "it just happened a couple of days ago. Can I reset it in settings or something like that?"

I'm amazed at the range of comments regarding this system; they range from unbridled enthusiasm to some **** words.
Before I try to help, if I am not familiar with a specific model but have a clue to what the nature of the problem might be, I research the item to see if I find some support for my suspicion.
You might keep tabs on some comments I found relating to a possible class-action lawsuit due to the array of problems that have appeared with this system.
This link will give you a sample of them:

Hey, try this out
-Press Enter and On/Off on the media center , on standby mode
-now hold the enter button pressed and start pressing the On/Off button. You should see a setting display on the player. The setting on display should change from video....till...Hotel Control -ON
- on that position, press the Volume 'minus' button on the media center. It should change to Hotel Control - Off.
Thanks

SOURCE: bose 321 system reads bad disc on all dvds
if will not read a laser lens cleaning disc , then it will need to be opened up and the laser lens will need to be cleaned manually with the cleaning solution and a cotton tip , but do it easy and dry the lens with the cotton tip
if that don't do it then the laser mechanism will need replacing

-If this happens on all DVDs, then this may need to be repaired (Bose will repair this for free if this is the case- they can test it too)
-If this happens on some or most DVDs, you can try a firmware update. Call Bose at 800-367-4008 and tell them about this. Request the most recent software/firmware update disc.
If you haven't already, just try resetting this first. (unplug the power cord from the acoustimass module for about 30+ seconds and try again)
If this happens primarily on rentals or home-made dvds, an update will most likely fix the problem.
