Had the same problem this evening. Audi A6 C7 with phone prep in the arm rest.
In my case, a gum wrapper had shorted across the exposed pins in the armrest. Quick shuffle around and back in business! !

I got this problems 3 times since last August which I bought the car. Haven't tried resetting the MMI when the problem comes back.

My Audi with B&O audio was suffering from intermittent sound with increasing frequency. I replaced my battery with on OEM equivalent AGM battery and the problem stopped. In retrospect, I am pretty sure that when the sound would drop out was following stops while running errands, but not every time.

Dealer had advised an amp replacement @ $2100 US.

I speculate the system voltage was dropping down with starts and not recovering fast enough before intermediate stops as the battery was slow charging and suffering from lower cycle capacity. Thus lower input voltage to the amp causing the drop outs.

My battery was the factory original AGM battery with a 2/2010 date. Over seven years is darn good.

Hi Has anyone experience a problem with the bluetooth audio player?? I have a 2015 a3 premium, and every time I try to play a video from instragram, snapchat, or videos from my iphone 8, it won't play the sound at all, but at the same time when I play music that does work. If I play music and I keep it on, only then I am able to listen to the sounds of videos of Snap Chat and Instagram, but since I have the music in the background I can't hear anything really. The sound from videos of my gallery will not play regardless :/ I need some help!!!

I have a 2008 Audi S5 and I live in Alaska, I just got my car out of the shop and the sound mysteriously stopped working. The MMI is on and I can use the interface but there’s literally no sound not even static. Anyone know a possible fix??

I have the same car and the same problem, I'm still looking to get it fixed. Have you found a fix?

Hey there... I have a 2011 Q5, 126,000 miles. This morning, the sound for the MMI would not work regardless of what I tried. No sound for radio, phone, CD, NAV... NOTHIN' ! I tried the three button reset, but no change. I tried turning off Bluetooth, thinking that maybe the auto mute from a phone call or Waze might somehow be engaged (as it intermittently operates properly... or not), all to no avail.

FINALLY, I resorted to opening the fuse box in the luggage compartment, removing and reinserting the E3 and E4 fuses (DSP Amplifier and MMI) and everything is now back working perfectly. Maybe after 10 years of vibrations they just needed a little wiggle to re-seat and start working again.

Good luck, your mileage may vary ! ;-)
