This supported codec list you show is for playback. Not for Bluetooth.
Otherwise it would say you can play AAC+ or FLAC via Bluetooth, what is not the case.
I find it confusing as well, because SBC would be missing in that case. I’m just repeating what support told me with this list. If we cannot trust that as a source, then I don’t know what is.
I am sorry but this time the support was wrong to you.
I trust the Fairphone answer in one of the threat that dev team is taking care of it to correct.
And as I have a 4 - I can tell you that aptx - until adaptive, (TWS I could not try), AAC, LDAC was working. Even AAC is still working with 12. Prove by the receiver that show the type of codec used - in addition to the message in Fairphone 4.
To my knowledge:
In case you have a SoC from Qualcomm - you get by default aptx support as it is built-in in hardware.
If you get aptx adaptive or hd do more pend on type of chip and modem used.
Aptx is qualcomm proprietary content - and so I can understand you need license if you do NOT use SoC from Qualcomm.
Here Fairphone do have Qualcomm - and so you have aptx support.
I do not have heard of any smartphone with Qualcomm NOT having at least one aptx codec. This since my first - HTC Desire.
It would be more questionable for LDAC support as SONY proprietary Codec. But even this runs with the Fairphone 4.
As even the aptx is not working - that must be a configuration error in the kernel modules in Android12. The behaviour of Video playback (slomo) is for me a clear indicator.

To complete:
LDAC is still working with Android 12.
Only aptx - in all version - fail.
So I can still use my PX7 with appropriate codec - but need a Fiio M5 in the middle.
Hi there,
I also can confirm that aptX did work on FP4 Stock Android 11 with 2 different bluetooth audio devices capable of aptX. Since update to Android 12 only silence if I use HD-Audio and aptX is shown in the properties of the bluetooth connection. Switching off HD-Audio immediately solves the problem.
I’m not happy with this solution. Audio quality has significantly degraded 
Please solve this issue, dear FP-Team!

Hi and welcome to the forum.
As this is a user forum with Fairphone only really reading responses to their own posts you may find it more satisfying to contact Fairphone via their support page or by email to support@fairphone.com

Fairphone already accepted this bug and confirmed to work on it, no need to bother support with this

I can confirm, the issue only appears when using aptX; if you go to developer settings and switch to something else (in my case LDAC), the audio is back.
If someone from Fairphone is looking at this thread: It would be nice if, in addition to fixing whatever issues there are with aptX, the phone could default to using the highest-quality codec available for a given headset as well. I raised this issue with support about a year ago and was told there is not enough interest to consider a fix, but since Bluetooth audio is getting some attention now anyway, maybe the codec prioritization could be tweaked as well. I shouldn’t have to manually switch to LDAC from developer settings every time I connect my headphones to get the best-quality audio available.

Looking forward to them fixing HD Bluetooth!

Android 11 with Bowers & Wilkins Px8 - AptX worked fine
Adroind 12 with Bowers & Wilkins Px8 - nothing works at all. Phone shoes that the aptX Codec is active and the sound is running but now played on the headphone.
How long does it need for a fix? I am not the smartest fp user, so downgrading to Android 11 might kill my data xD
Any experiences?
PS: A2DP disabling doesnt change stuff and also disabling aptX in developsettings didn’t fix the problem.
PPS: Yes aptX was not shown on the technical details … I went to a shop and tried a headphones, they worked, I bought them … coming up with “havent you read the technica lsheet on your phone blah” is definitely the wrong way to approach people in this thread.

It may not be the most useful/helpful etc. but the ordinary users that respond spend a lot of time answering issue that people could have found themselves had they put some more effort into it.
So it’s definitely not the wrong way to approach people when it seems they could have done more research on this forum before asking for help.
It’s a bit blunt, no doubt, but gladly somehow you got to the
As I’m not certain you’ve tried in the correct place or if anyone else gets lost, I believe the simplest/main workaround isn’t using the developer options, but to turn off HD aptx within Connected Devices (Bluetoothl settings - click on the cog next to the connected device to get to Device Details as seen here:

I am also having issues with my bluetooth from my fairphone to my earphones after the recent update. It manages to connect the devices but then when I try to play music I just hear clicky noises in the earphones. The phone was able to connect to a different wireless speaker, and the earphones are working fine connecting to my laptop, so I am not sure what exactly has gone wrong; it seems the phone has taken specific issue with the earphones! The earphones are goji GTCIBTB18. I have tried the “forget device” option for the earphones, in the bluetooth settings, and then the restart in Safe Mode (to disable 3rd party apps) but it is still doing the clicky noise. Any suggestions? Thanks!

Assuming you updated to Android 12 I moved your post here, please read above
If you use high quality ear buds and pay attention to good sound, it IS important, as it makes a real difference.

It’s the simplest, but for those who are audiophiles and really concerned about the best quality, there is also the option to have that. 
It’s almost a necessity to be honest, because the LDAC bitrate is about double that of aptX HD, but for whatever reason FP always defaults to aptX when HD-audio is enabled, so if you want the best you have to regularly tweak the settings anyway.
The FP4 supports AptX HD. This new issue is unique to the latest software update.

I ended up installing Bluetooth Codec Changer which makes this a little bit easier. It also has an auto switch feature, but sadly that’s only part of the premium version ($3 one-time, so could be worse I suppose).
