I am a total newbie to Linux but I have not been able to find a forum post or wiki resource to help me with my Dell XPS 13 not being able to even detect my bluetooth headphones. My laptop can recognized other devices, it works with my dualshock 3 but none of my headphones. Any help or resource is appreciated.
What kind of headphones are they? Have you been able to pair them with other things (your phone perhaps)?
Are you on 5.14 on purpose, or have you not updated in a while? I would start by doing the update (just type update into the terminal), then power off, wait a second, then boot back up and try to pair the headphones again.
They are Sony WH-1000XM4s. I can connect them to my phone no problem. I just updated the system but I still can't discover my headphones. The bluetooth address doesn't even show up when I try to add a new device.
Your headphones look like they do their first device pairing automatically, but after that you have to hold down the power button for seven seconds to get back into pairing mode for any additional devices.
I've seen many cases in the past year where most Bluetooth devices were working fine, but BT headphones could not connect on a specific kernel, (yet another kernel it worked fine). Bluetooth functionality breaks quite regularly on kernel updates. That is why my first suggestion on many BT threads is to test alternate kernels.
You know what? That actually makes sense because the headphones are constantly being released with new bluetooth protocols, while a controller or mouse or something would probably just have plain ordinary BT.
From the Sony WH-1000XM4 website:
"LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional BLUETOOTH® audio..."
The error message below could mean you have firmware issues:
Your BCM20702A1 bluetooth chip requires installation of one of these proprietary firmware packages:
Reinstall whichever of the broadcom firmware package above you are using, and then reboot. If there is no improvement after re-installation, then uninstall whichever package you are currently using, and then install the alternate firmware package I have listed. Reboot after the new firmware package has been installed.
You should also ensure your bios is up to date.
We are now on post 14 of your help request, and you have still not responded to the first question/suggestion put to you on post 2.
This query was put to you a day ago on the first response on this thread. Since then, several moderators (@SGS and myself) have asked you to update your system and install an alternate kernel. You have responded 4 times since these suggestions were put to you. In none of your 4 responses since yesterday have you confirmed if you have implemented the suggestions put to you by 3 different forum assistants.
I realize you are new to Linux, but this behavior is simply unacceptable on our forum. If you want help, you are expected to provide full feedback to any and all questions and suggestions put to you. This is just common courtesy, but that is not the main reason for this expectation. Your issue will, likely never get resolved (or it will take far longer) if you fail to confirm what you have tested and the results of all troubleshooting suggestions.
If your next post on this thread does not contain information on whether you have fully updated your system and tested at least the LTS kernel, (preferably others as well) your thread will be locked (as this thread is pointless without proper feedback from you). I have also given you new suggestions in this post, please provide feedback on my new suggestions as soon as you get a chance to test them out.
I appreciate the fact you are new here, but you are still expected to be cooperative with forum assistants, regardless of how inexperienced you are.
My apologies. Please forgive my lack of response. I truly appreciate everyone's help and patience. I'm learning as I go and will be more thorough and consistent with my forum activity in the future. I updated my firmware, installed the two firmware updates with no luck. I'm going to try the LTS Kernel now.
Ok I tried the LTS Kernel to no avail. I'm not sure if I updated my bluetooth firmware correctly though. I think this might be a lost cause in that my laptop's bluetooth module is too old for my headphones. I really appreciate everyone's time and help.
It does look like there is a BIOS update (October 2019) for your laptop you can install. It's kind of a hail mary for the BT issue, but it looks like a security patch so you should probably do it anyway when you get a chance.
I'm not sure what that output is. What are you trying to do?
Is that the BIOS update? That update cannot be installed in Linux, you have to go into the UEFI BIOS menu and install it there.
First you need to format a flash drive as FAT32 and save the update file (uncompressed) on the flash drive. Then reboot your machine, and the moment you see the Dell logo pop up you hit F12 to get into the UEFI BIOS menu.
There should be an option in the menu called "BIOS flash" or "BIOS update", something along those lines. You may have to disable secure boot to get into it (you can disable secure boot from the BIOS menu as well, it may be on a different screen). Also it might insist that you plug in your laptop before it lets you do the update.
With any luck, your BIOS will be nice and modern and recognize what you are doing and try to help you. I've never had that experience; if yours looks anything like mine you will see a kind of bizarre looking, super basic file manager where you can navigate into a few folders to look for the update file you saved to the disk. On mine the drives were named fs0, fs1, fs2, etc and my EFI partition was on there along with the flash drive. I think any FAT32 partitions it can find will be in there. Just look around until you find the file, it should be all by itself and not buried in any folders or anything (heads-up: it might be named differently than you remember).
Once you find it and confirm you want to update you should be all set.
