Speakers not working!

Hello,

2021 M5 with HK speakers. Took it into dealer earlier this week for the 1200 mi break in. Today, I noticed only the satellites are working! There is ZERO bass--it's like the other speakers have stopped working! I tried restarting car, but no luck. I checked the EQ settings and all looks ok. Is there a way to reset the speaker system or a quick fix for this? I'd rather not have the dealer start fiddling with the interior...

Thanks,
FS

This has happened to me a few times as well on my 2021 m5. It fixed itself after turning off the car overnight.

Weird. So some weird electrical gremlin? Any idea on a fix for this? I definitely don't want this to keep happening...

Same thing here. Almost every time I drive it, it will do that then it comes back. Could be a software issue. I’m just glad I’m not the only one.

This has been an ongoing issue with some cars. I recommend subscribing to the following thread for a potential solution.

No base from HK/B&O speakers

I brought my car in for the issue, they are replacing the amp.
I will know tomorrow if that was the issue or they just threw parts at it.

I am glad I found this thread since I just took delivery of 21 M5C with B&O and honestly the bass is super disappointing. Sounds like it has no sub at all. And no controls for sub in sound settings? Bullshit on BMW's part for not putting proper audio after charging $3500.

Just picked the car up, they put a new amp in, fingers crossed it fixes the issue.

Dealers don't really know what to do besides replace modules. There could be an unplugged wire harness and I swear they would still just replace the amp anyway. 😆
