Is anyone else aware of the TERRIBLE streaming quality via Bluetooth? the mids get crushed and sound terrible when I connect my X to my car. Did some research and found a fix for the GNex here:
http://forum.xda-developers.com/showthread.php?t=2184333
I tried to apply it to the X but it turns out there's no bluetooth-default.so in the system/lib/hw folder ... only a2dp.default.so
I replace just a2dp.default.so with the 'fixed' ones from that thread and then my phone wouldn't hold a connection to the car (Gmusic kept telling me "cannot play requested stream") and when I toggle off/disconnect from bluetooth my phone would reboot.
anyone got ideas for a fix?
there is a directory called bluez-plugin and inside that there's an audio.so and a bluetooth-health.so but I dare not mess with them hehe.
I haven't noticed poor quality streaming at all... I have used it a lot.

The Moto X doesn't use the AOSP bluedroid stack, they stuck with Blue-Z stack so it doesn't have the same problems, and you can't apply the same fix (as you discovered).
My experience has been 100% positive with Bluetooth audio on this device, it sounds just as good as the fixed AOSP bluedroid stack does to my ears on all my BT receivers. I don't know for certain but it's pretty likely that the Blue-Z stack Motorola used is newer than the last one we saw in AOSP (Android 4.1) and there is probably an incompatibilty with your car if it really sounds that bad.
Before you guys jump all over me and call me an idiot ... I happen to be the guy that came up with that particular fix for the AOSP bluedroid stack in the first place :silly: (http://code.google.com/p/android/issues/detail?id=39632#c151) <--- woot! I'm this guy! LOL, whatever, I know. What the fix essentially did was set the bitpool (like a buffer) to the recommended size for high quality audio, but modern Blue-Z implementations didn't suffer from the same problem. It was introduced with AOSP Android 4.2 and persists in AOSP Android 4.3.
Do you have any other A2DP receivers to test against at your disposal? I've used my VZW Moto X against a Rocketfish Receiver (http://www.rocketfishproducts.com/products/home-theater/RF-BTR212.html), an HDMX Jam (http://www.hmdxaudio.com/jam-classic-wireless-bluetooth-speaker.html) and most recently a Bose Soundlink Mini (http://www.bose.com/controller?url=...s/bluetooth_speakers/soundlink_mini/index.jsp) -- playing as I write this post -- it honestly sounds just as good as my fixed Fascinate and my fixed Galaxy Nexus did, perhaps even slightly better!
Moto X A2DP = djp952 certified! :victory:
I have the same issue with poor sound quality when I stream music to my 2013 Subaru Legacy stereo. The problem seems to be that the sound is overly compressed and when a lot is going on it becomes especially noticeable. Part of the issue revolves around devices that don't support the newer APT-X codec, if the device supports that codec the sound is said to be fine however any device that uses straight A2DP will experience this issue.

I have had the same experience as you. I have tried my Moto X with about 10 different bluetooth receivers. I have had nothing but excellent sound quality.

I'm experiencing the same crappy BT audio I was with my galaxy nexus prior to your fix (thanks a lot BTW) on my moto x with the same BT receiver in my car. I've got a couple others I will try and report back later.
Moto x doesn't sound good on any BT device I have but none of them support apt-x which the moto x does? I know the rocketfish you mentioned has apt-x but not sure about the other 2. If they do maybe that's the difference in sound quality?

I'm not sure either It's a good bet the Bose one does since its brand new. Seems like a pretty good theory!
I think I still have a really really old Scosche receiver kicking around somewhere I can try for you guys and compare it with an AOSP bluedroid-based phone.
http://www.csr.com/gogroove-bluesync-portable-bluetooth-speaker
Forgot to test on that which does have apt-x though I don't think it specifies in the manufacture or amazon site but that's the actual apt-x website. Can confirm that it definitely sounds better than my other devices.
Some Test Info if it helps
I have the same audio quality issue with my VZW Moto X, constant crackling noises, but I only experience it with one bluetooth receiver (of the ones I have available to test). Unfortunately, it's the only one I have built into my primary vehicle, so it's extremely frustrating. I don't have any data that indicates what these products support in terms of codecs, but here is some info if it is of any use in diagnosing the problem:
Pioneer DEH-X9500BHS - Works Great for BT-Audio and Pandora Mode
Satechi Soundfly View - Works Great
iSimple Connect ISHD651 installed in a 2008 Honda Accord - Worked Great with my Droid Inc 2, but horrible crackling with my Moto X.

I don't see any indication that states that deck supports apt-x. I read on the android bug report page that one user running 4.4 claims they've finally fixed this issue so I guess we wait for 4.4 now.
The deck does NOT have to support apt-x in order to sound good. The moto x is the best sounding bluetooth device I have ever connected to my deck, and my deck for sure doesn't have apt-x. I am so up tight about sound quality that i've always used a cable to connect my devices. The moto x is the first device I have used where I no longer need the cable and have thrown it in my closet somewhere.

My Bose Infiniti head unit sounds amazing streaming Bluetooth from my wife's iphone4s and a load of rubbish while streaming from my motoX.
I'm very close to just saying screw it, giving in, and buying an iPhone.

I have experienced Bluetooth backward compatibility problems with my note 8 on devices having early bluetooth versions. For instance I have a monster rocking roller speaker that worked flawlessly with the s7 and with my N8 I would have audio distortion and crackling.
With the delivery of Oreo there are a bunch of Bluetooth settings to play with in developer options (attached) and I was wondering if anyone has had success tweaking these settings to solve an issue like I have been having.
I never used any of the settings and no BT issues here (Speakers, car audio, smart watches, wireless headphones/earbuts).
Maybe your speaker has a problem...

Have you tried messing with the sound-alive settings the phone uses? The drivers it uses suck! Ive noticed in some cars it was the issue, ive moved away from samsung drivers all together and use viper for a solution but being unrooted your stuck with using what you got

I didn't but I changed the codec setting from acc to sbc and messed with the sample rates and I now don't have a worthless $200 speaker. This seemed to solve my previous problems.
I've been having a similar issue my stereo in my truck is supposed to launch my Bluetooth music players and allow me to control the music player from the stereo in the truck but it does not now since the update any idea on what settings I should use for what they were before the update?
I use the aptX codec on my Bluetooth headset. What's up??
Hi, I understand the P20 Pro hardware supports aptx and aptx HD butdoes this work out of the box or does a codec need to be installed? I can see it in the Bluetooth section of the developer options but I can't select anything but SBC.
Thanks

Does the option only change when connected to a compatible Bluetooth receiver? I thought my car receiver was compatible but if that's the case then I guess not.
I had the same issue with regards to Bluetooth defaulting to SBC, after some reading I discovered that it was possible to change the Bluetooth mode on my headphones by holding a button combination, it went from prefer connection to prefer sound quality and unlocked aptx and LDAC on my Sony MDR-1000X. So the P20 Pro is definitely capable of it without any additional codecs.
Maybe read the manual for your device and see if it also has something like this.

I have this problem too.
On my OnePlus One i can change the audio codec, it should not depend on the bluetooth headphones connected. My Mpow Wolverine sounds way better with the One Plus One, on the P20 pro it sounds like sh*** ;any suggestion?
I have headphones that are both SBC and AAC compatible.
Paired to my pixel, aac works great.
Paired to p20, it sutters, skips and is stuck on SBC
I noticed when there is an actual icon just after the Bluetooth device name of my headphones that says 'APT-X', in the phones Bluetooth settings.... My previous Huawei P9 didn't have it or support it so did surprise me a little as I didn't look into it when switching.
On the P20 you can change the BT codec (in developper settings) but the settings doesn't stay...

Yes, same to me.
It's a bit frustrating, seems like i have to buy another Bt headphone, also another usb c headphone.. but that is another problem
Same **** here, guys.
PowerBeats 3 are in AAC with Pixel and S9, but in SBC with my P20 Pro. And I also hate that EQ is not avaliable.
I have emailed Huawei, but those dumb idiots are asking for IMEI and system version... They don't realise, that it's a wide problem....

Contentear Huawei Team, I have purchased my P20 Pro during a first sales week at your store in Singapore. In general, I am happy with it, but, I have COMPLETELY confused with your audio experience. PROBLEM: I own two pairs of headphones: Bose QuietComfort 30 and PowerBeats 3. I don't understand why I am not able to tweak EQ over the bluetooth! S7 was able to do it, old Sony Z2 was able to do it too, but 1000$ phone by Huawei with triple camera and AI can't provide damn equalizer! I don't need any processing by Dolby, I just want to add some bass, because I am lisening to EDM, not a classical music, I don't need a analytical audio presentation. Then, codec selection is broken! PowerBeats are not able to get their native AAC, and Bose are working in SBC mode. What a shame! I can't tweak audio, and I have to listen compressed nonsense. I didn't expect that I will have to deal with such problem in the 1000$ phone. Please, release the software update, I would like to have at least eq.

Has anyone got aptx HD working? Is it much better sound quality than ACC?
Thinking of buying some Sony 1000xM2 which are aptx HD compatible but if the sound quality isn't any better, I won't waste my money

My Sony MDR100's use LDAC and sound great. They have a built in EQ profile that kicks in once they are powered on according to reviews. I could of sworn it was using APTX HD at first but I was mistaken.

Ah, I didn't know the P20 Pro supported LDAC.
Just got to wait for my Bose to sell on eBay now
Tried on a few different headphones here. Seems apt-X is working, AAC is not.
110 firmware.
My p20 pro is on order and not arrived yet, but what you should try is:
1. Clear bluetooth connection of remembered device
2. Enable Developer settings, go to settings->about phone->click on 'buid number' a bunch of times (8?? from memory)
3. Go to: Settings->developer settings->the bluetooth sections and select whatever you want to be the normal
4. Re-connect your bluetooth device. If its compatible then it will default to your previous selection.
At least, this is how it works on my S8, Zenphone 3 deluxe and Oneplus 3T, with my Sony WH-1000XM2 and audiotechnica headsetsand WI-1000X.
But they all have custom roms and i have never had a Huawei so im not 100% sure.
In theory the Bose QC 35 ii headphones support both SDC and AAC but I can't select AAC in the developer settings. Are others having the same experience?

Yeah I get the same issue with the bose headphones but ldac works when I connected to a sony speaker
Im in the process of buying some earphones that supportthe newer aptx low latency codec as I will be using them for gaming aswell. We know p20 pro supports aptx and aptx HD but does it support aptX LL

Yeah just received my Anker SoundBuds Curve headphones and it shows aptX next to the connection in the bluetooth settings. I guess AAC isn't supported as it's not listed on Huawei's tech specs page- https://consumer.huawei.com/uk/phones/m/p20-pro/tech-specs/ I also don't see aptX LL on there so I supposed that's also not supported
I've changed nothing. Only installed .128 Firmware with funky Huawei. When I connect my Ultrasone Sirius Bluetooth Headset there is automatically a aptx-Icon near the name. Nothing to change in developer-settings. See my picture on instagram:

I am hoping someone can take on the project to write a mod that allows Pixel 5, Android OS 12, to play audio on two separate Bluetooth devices at the same time like Samsung. I recently bought a Woojer Strap Edge for audio haptic feedback, it connects wired or via Bluetooth. I use Bluetooth headphones and Pixel 5 does not allow audio output to two Bluetooth devices at the same time even though the hardware is capable of it. Is there anyone that has the know how to reverse engineer Samsung's Dual Audio Playback and make a mod to unlock these features on Pixel 5 Android OS 12? Or is there a known fix for this already?
Nothing in developer options allows this to work, I have played with all of those functions already.
I greatly appreciate any help, I know that this is an issue for many people across many devices, a broad fix would be fantastic if possible. I am not a code engineer, so not even sure if this is possible. All info will be helpful. Please let me know if you need any further information from me.
Hey there,
so I've ordered the Sony WH-1000xm4 and Linkbuds S, both with LDAC, but no aptX support.
To not be trapped in bad functioning SBC/AAC I want to activate LDAC to listen to my .flacs and co.
Heard I have to go for customROM to do so, as I do have Android 12, but Xiaomi does not support LDAC.
Also, Dual Sound, which means I can play one song on those two headphones simultaneously from one device
is supported by Samsung software wise, which means a customROM should also be able to do so I guess.
Xiaomi launched something similar a year back, but just for 1-2 flagships and you can connect at the same time,
but not play music at the same time with the headphones. (Both of mine have multipoint btw.)
Do you know of a customROM that matches both wishes?
Thaaanks
+1, after a long research i have no solution ford Dual Sound or dual Audio. Any mods or custom ROM to do that?
