Speaker failure when getting warm

Hi,

I have a new one:
Since a few days, the speakers fail when the FW12 heats up during charging. When I lift it on the front, so the chassis slightly bends downwards, I can hear sound again. When disconnecting from the charger and the battery cools down, speakers start to work normally again after a few minutes.

I already checked the sound board, removed it, cleaned alle the contacts but no improvement.

Anyone with similar issues or advice, before I open a ticket?

I have a similar issue, though it only affects my left speaker so far. I had not initially connected the heat factor, as it mostly seemed to be affected by which way the bottom case was flexing: if the case flexes with the bottom left corner flexing up (towards the screen) the speaker goes out, if I put slight pressure in the opposite direction (or prop the machine up with a pen under the right corner) the speaker comes back. When I’m typing some key pressed on the left side of the keyboard can cause the speaker to start/stop working, and if I press down on the top of the case about 2” left of the trackpad both speakers go out until pressure is removed.

However the battery/thermal impact also fits my symptoms as occasionally the speaker will go out while the laptop is sitting on a table plugged into power but not actively being touched.

I also opened the machine and inspected the audio board. No visible issues with the hardware or contacts. My next plan is to see if it’s possible to safely shim under the audio board (essentially providing that slight upwards flex), but that seems like a suboptimal solution.

@Lukas_Angermayer if you wound up submitting a ticket and have learned anything more please let me know.

@Lukas_Angermayer I’m dealing with the same thing :frowning: No idea what’s causing it though, just joining in with @drags to see if you got any updates at all?

I did not submit a ticket yet, but tried something myself:
I added some small piece of foam under the speaker contacts to push them upwards to the audio board. That helped a bit but not 100% against heavier case flex.
Then I tightend the bottom screw near the audio bord a bit stronger, and that fixed it (for now),

On the other hand, I fear more risk of case cracks in this area now :smiley:

I’ve just been trying to diagnose the same problem.

I think what is happening is that the pogo-pins between the audio board and the speaker connector disconnect when the battery connector (which is next door) gets warm during charging.

An update for my issue.

The issue suddenly got a lot worse around a month ago. In the last few weeks it got so bad that the left speaker basically never works, and plugging it in to charge would cause both speakers to stop working.

When I finally had some free time I went to open the machine again to inspect the audio card, but upon flipping the machine over to undo the screws I found this:

Not the clearest picture, but if you look at the bottom left corner of the silver expansion card you’ll see a 4-5cm long crack spreading towards the middle of the case.

There is an ongoing issue reported in August 2025 for FW12’s which have their bottom case cracking: [TRACKING] FW12 cracking issue

I believe this was the actual cause of the audio card issue, so I wanted to include an update here in case it clues other folks in to cracking issues with their own cases. Not sure if it’s the actual cause for the seemingly related issue from others in this thread, but worth checking on.

I’ve opened a support request to get a new bottom case, once I have it swapped I’ll update here as to whether I have any more audio issues.

I took a look at the bottom of my laptop after seeing your post and, lo and behold, I also have a crack in the exact same spot. :upside_down_face: Go figure! Definitely keep us posted; if swapping the bottom case out fixes the issue I’ll definitely be following in your footsteps! You’re very appreciated!

Update from my side: I recently got a new bottom cover the speaker issues are gone :partying_face:
So it seems this is somehow connected to the cracks in the case.
Now I hope for no more cracks, but since the manufacturing date of my “new” bottom cover is week 47/2025 I suppose I will need one more bottom cover soon :cry:

Hopefully not. Week 50 and on is when Eagle said they can say for sure that ALL colors are definitely of the updated geometry and plastic formulation. But some colors had updated parts being made before that. So, fingers crossed you don’t have any more issues.

Just chiming in a bit late here. Support got a new bottom cover out to me quite promptly, but I had a very hectic May and couldn’t do the swap until this past Sunday.

Happy to report that my speaker issue was also corrected by the replacement bottom cover. Before replacement the issue had become so severe that the left speaker never worked, and the right speaker only worked when the machine was either not plugged in, or fully charged. Since replacing the bottom cover both speakers now work 100% of the time regardless of the battery or charging state.

Mostly just responding in hopes our experiences help others with similar issues in the future. Thank you to everyone who participated here.

I’ve got some experience fixing up electronics so I put some solder on the pads of mine to make them functionally taller, which has been working out pretty well so far. That said, I’m glad swapping out the case seems to work because that’s much easier to do : )

Bottom Cover replacement worked for me!

My symptoms:

  • Speaker sound was intermittent
  • Left speaker would often not work at all
  • Sound would stop when I turned my FW 12" upside down
  • I had one crack in my Bottom Cover and accidentally added a second during troubleshooting (tightened the audio board screw too tight)

Based on this thread, I ordered a new Bottom Cover, did the swap out, and full sound came back immediately, yay!

I’ve had a similar problem for a while, and would you know it- when I flipped my case over there was a crack in it. I’m going to have to look into getting a replacement as well.
