Hello everyone!
I suppose that doesn't work Apt-X codec when I heared music thru Bluetooth Samsung HS3000 (apt-X codec supported) and Motorola Razr I which support apt-x too. I rely on my ears and data from Catlog app (no data about aptx codec at all) now. I know that two divices (Razr I and HS3000) support apt-x and I suppose that apt-x is bloked on a software level in the phone.
Could you pls anyone share your experience on this direction? And if it is possible pls share your log file from Catlog app (like this) if you happen to find in it the "aptx"...
Also could you please share your /etc/bluetooth/audio.conf

Hi Alexae!
I have just tried Sennheiser PX 210 BT, with which I have the option to try with wire as well. So I did listening to some flac and mp3 music on my laptop and on my Razr I. My laptop is a Fujitsu A530 not known to support aptx and there was an easily hearable difference between the wired and A2DP listening. With my Razr I I could not distinguish between wired or wireless. Although running the Catlog app I could not find any entry about aptx (as there is on the page you have linked). Only the A2DP protocol enabling is mentioned. I prefer not to share my log file for privacy reasons as I not aware of the information it can contain.
Hope it helps. I think we are lucky with this phone.
[UPDATE] Looking into Aptx further it seem it only comes with the Bluetooth 4.0 and the Razr I only supports 2.1. So from that the answer is there is NO Aptx support in the phone.

Hi ladies & gentlemen, especially technical gurus,
Does anyone know how to add aptX for our SGT? I list some ideas, including "ridiculous" ideas, at least give you guys a good laugh.
What is aptX?

Proof of aptX is better than SBC on electro-acoustic measurement in full digital domain --> http://www.prismsound.com/test_measure/webinars.php?wid=19
Download the 140MB video webinar. Really good. Thanks to Simon WOOLLARD of Prism Sound. Great organization, Great webinar Simon !!! KUDOS !!!
a xda member managed to find the log cat of aptX running in android phone
http://forum.xda-developers.com/showthread.php?t=1917962
So, choice of convenience / solution or by ranking of convenience: -
flash aptX codec into existing BT chip within Android phone. Requires purely software only. Does anyone have these software pacakges, tool, aptx codec? Mind me, aptX is a licence and needs to be paid, but surely CSR will not be collecting individually. Who am I to them
flash aptX codec directly into BT chip on phone PCBA. Requires software as above and needs to open up phone and hardwire direct to BT linkage. Can anyone do this?
Buy a 3.5mm stereo jack to BT aptX transmitter, choice of: -
http://www.jaybirdstore.com/s.nl/it.A/id.236/.f?sc=2&category=101 clearly shows aptX on the casing.
http://www.cndgroup.com.hk/e/product/product_detail.asp?sku=2127
but the chinese site doesn't says aptX at all http://www.woowi.com/product/201208/16.html#
Finally, unsolder out the Jaybird aptX chip and resolder into SGT and remove the old chip. Must be same PIN-OUT, manufacturer, type, etc. Kernel, OS, driver must support & match. Else doesn't work.
SGT individual PARTS breakdown, diagram,

BT chip is U202 1205-004045 - IC-BLUETOOTH
How about aptX LOSSLESS ?? http://www.csr.com/products/technology/aptX ??? pls click the lossless link. Does it mean currently on the market all are normal aptX and not LOSSLESS type?? the expensive type??
Just in case someone is interested, here's a forum chat with someone from aptX
http://www.hydrogenaudio.org/forums/index.php?showtopic=78217
So, let the ridiculous CHAT beginssssssssssssssssssssssssss.
Well, incase you like such stories, aptX was bought by CSR 2010 Q3, http://www.google.com.hk/search?hl=...252.1707.0j10j2.12.0...0.0...1c.1.rfb882TLcA4
then 2012 Q3 Samsung bought the bluetooth division of CSR, of just the aptX division of CSR, well "mobile business" they call it, not the entire CSR anyway. http://www.google.com.hk/search?q=c...sugexp=chrome,mod=13&sourceid=chrome&ie=UTF-8
I tested one of the aptX combinations,
phone is S3 HK, rom is still original 4.1 I think, virgin, no root.
headphone is Denon AH-W200.
music player is default from S3. EQ setting is flat, nothing else engaged.
Other settings unknown, it's not my phone, not intruding to borrowers privacy, didn't manage to check other software settings.
Wired sound is termed as "MIDDLE, or normal". We are not reviewing AH-W200, we are just comparing between aptX vs. wired, vs. normal BT.
listening test (subjective), wired versus BT (assuming aptX is default engaged, as says by CSR)
During BT (assuming aptX is engaged), the bass is overloaded, not yet full distortion, not even slight distortion, just a good 10dB more than wired.
mids and highs are nearly as good as wired. Some moments can hear high frequency loosing out, but most of the time, ??? 80% or 90% is nearly as good as wired, if I did a blind test, probably I would know, but some moments it's just obvious lost of highs like old BT in SBC mode.
Should have borrowed the AW-H100 as well which is all same supposingly, except without aptX.
Anyway,
BT SBC vs. BT aptX
Obvious difference, BT SBC lost of bass even to wired, lost of highs is significant. Midrange clarity suffer some, but unknown if not perform a immediate swap A B test.
BT SBC was from P1000, rom alroger's 4.1.2, xing player apk, DSP manager all flat, WM8994 in all default settings, direct DAC, Hi-Fi playback.
Headphone is AW-H200
Verdict = aptX has significant improvement over SBC, I'm a believer now, but am not satisfied with the +10dB bass boost. Was it Denon's engineer liked bass so much added a EQ setting when aptX engaged?
Who know????
I'm trying to figure out if any of my bluetooth devices support atpx for a higher quality sound. Is it possible in Android to see what codec is being used when streaming music/audio over bluetooth?
logcat, look for apt-x when connecting to apt-X enabled device

Post edited for quick answer.
I've confirmed that the Xiaomi Mi Mix supports both APTX and APTX HD. I'm running the 8.2.5.0 MAHMIDL global ROM without modification.
TL;DR
Equipment and software used:
Audio Technica ATH-DSR9BT Bluetooth headphones.
Xiaomi Mi Mix 256/6
Onkyo HF music player with pro unlock.
Laptop with Wireshark
Protocol:
Tap phone to headphones for NFC facilitated Bluetooth pairing with ATH-DSR9BT.
Verified pair by playing a FLAC file on phone and listened to playback on headphones.
Stopped music and turned off headphones.
From settings, developer options were activated by tapping the MIUI version (ROM build) several times.
Activated Bluetooth HCI Snoop log through:
Settings/Additional Settings/Developer Options/Bluetooth HCI Snoop Log (on)
Immediately turned the headphones back on, and played the same FLAC music file in Onkyo HF Player and listened to playback for about 8-10 seconds.
The ATH-DSR9BT headphones themselves feature status lights that indicate which CODEC is being used for playback. Indicator light 3 flashed purple every few seconds, which indicates that APTX HD is being used.
For absolute certainty, the HCI Snoop log from the phone was copied to a laptop and opened in WireShark for analysis. The Xiaomi Mi Mix and the ATH-DSR9BT negotiated a vendor CODEC (0x0024) where Qualcomm was the vendor. More specifically, the CODEC was verifiably set after it was exchanged in discovery as SEID audio sink 7. The CODEC was verifiably set via the set command recorded in the Snoop Log.
APTX was also offered, but wasn't selected as it is inferior to APTX HD.
In any case, that puts this question to bed. I suspect that this isn't an advertised feature because it may not have been officially implemented and could have been made available after release and after marketing material and specifications were already released.
Thanks, and get yourself some good headphones and enjoy Bluetooth audio on your Xiaomi Mix in high fidelity.
i quote a review detailled :
There’s also no aptX support here for high quality Bluetooth audio either, so Bluetooth headphone or car stereo users may want to look elsewhere for a higher quality wireless audio experience.

I'm not referring to out-of-the-box capability. I'm asking if there are ROMS that enable it because the hardware is already there.
Car audio comes across great on mine, wouldn't probably notice it if it had aptX ...

Hello fellas,
I am creating this new thread as I have searched for relevant topic in this Red Magic 3 Forum and found none.
So let's discuss the issue that I had and I am certain most of you guys red magic 3 owner or Android owners face too.
I have purchased a bluetooth earpiece called pamu slide T6 from indiegogo (this is the URL https://www.indiegogo.com/projects/pamu-slide-born-for-music-never-fall-out#/) and this earpice supports aptX codec which is the latest codec from Bluetooth that can provide a latency as low as 30ms compare to SBC/AAC that about 300ms.
The reason I purchased red magic 3 is solely for gaming purpose, mainly PUBG Mobile and I purchased this bluetooth earpiece just want to try and pair it while playing but when tested, the results are very worst, delay audio, out of sync with the action, jump, crawl, shoot, steps everything in the game audio was delayed so much almost 1 second.
On red magic 3 bluetooth device, I click on its settings and there shown that it is using HD Audio:AAC (meaning it is streaming using AAC codec) which explains the delay because AAC codec streams around 300ms latency (I got this info from soundguys)
Next, I go to developer settings and tried to change the AAC codec to aptX but it just wont stick to aptX after I select it and click Back from developer settings, I go in the settings and it is still showing AAC codec as the codec, not aptX. Tried to restart the phone and re-pair the bluetooth earpiece but still, it sticks to AAC.
So I came to a mind whether my earpiece fool me and I pair the earpiece with my samsung galaxy S7 edge and my s7 edge is using aptX codec so which means my earpiece does support aptX codec and tried PUBG Mobile which I am shocked that it is still delay just the same as using red magic 3, i mean how can it be although my s7 edge has used aptX codec ??
I read a lot on google and most articles said that the problem is not with the bluetooth earpiece but it is the Android issue that does not support real time sync audio with bluetooth earpiece because how the Android OS process their system files etc.
But I just want to make sure that my phone red magic 3 does support aptX codec and I just cant change it to aptX, why ?
Additional findings: While the iphone (IOS) pair with apple airpods, the codec they use is AAC but the results are spectacular, no audio delay in gaming PUBG Mobile, everything is perfect, the steps, shoot, jump, etc are just like using a cable earphone. I am amazed at how IOS developers can do such thing that makes AAC codec stream so perfectly in sync between iphone and their own airpods. I test this using iphone 8+ with apple airpods gen 1
So in the end, the root cause why Bluetooth audio cant work with Android phone is because of the Android itself.

Incoherent, contradicting itself, juvenile... This is how this post sounds to me.
Hey, buddy, how about hundred of thousands of people who never experienced your problems with your crappy Indiegogo earbuds?

I solve the problem with magisk aptx. Its because aptx nubia not paying Qualcomm? I don't know what. But i have kz aptX and i solve the problem. Btw my bludio don't have aptX or aac codex still works fine in pubg. It's Bluetooth 5.0
Just got the reply from redmagic support and they told me that the phone does not support aptx codec. Lol I am very shocked tho after all it has bluetooth 5 but still no aptx codec.
Well, question answered and mystery solved. Admin can close this thread as no more discussion is needed. Thank you.
my bluetooth earphone is aptx supported and i connected my earphone and trying to activeaptx audio but SBC is default when i selected HWA it is not workig .and stereo audio left channel and right channel is not working it is steel mono audio .
I have a WH-CH700N Aptx-HD BT set from Sony. Worx fine out of the box (can see in the Sony Headphone app)
No need to install / configure in the OS
WH-CH700N supports SBC, AAC, aptX, aptX HD
Perhaps you need to install the app from the manufacturer. It is recommended for the sony
which BT headset do you have?
Meizu ep51 but sterio sarround not working
Meizu ep51 but sterio sarround not working
Hi, looks like it supports AptX but not Aptx-HD:
https://bluetoothcheck.com/a/meizu-ep52/meizu-ep51
If stereo is not working, then something else might be wrong.
Does a wired version work normally?
