Hello all.
I'm having problems with Bluetooth on my One. The device that I'm trying to use with it is called a Siemens MiniTek. (It's actually a hearing-aid accessory. You clip to the front of your shirt - it looks a bit like an MP3 player - and it plus my hearing aids together then function like a Bluetooth headset. So, when making a call, the sound is sent wirelessly to the hearing aids, and the device itself has a microphone on it.)
Making a call with it works okay; but if I try to use it to get audio out of my One in other conditions (playing a game, say, or watching downloaded video) then the video and audio are always badly out of synch - the sound lags at least one second behind the picture.
I'm using the stock HTC ROM, the latest one available in the UK (2.24.401.8).
Anyone have any thoughts as to why this might be happening and what I can do about it?
Mby there is too much data to deliver via bluetooth (high quality audi/video sound) and the hearing aid device is not meant to recive such a load.
When calling to some1, the sound quality is only like 24kbps or something.
Just a thought

That might result in there either being no sound at all or in the sound quality being very poor, but I don't see that it would result in reasonable-quality sound running 1 second behind the picture...?
The device itself is designed to handle fairly high quality sound: as well as receiving Bluetooth signals it can take analogue audio input via a 2.5mm stereo jack socket, and it also has a separate "base station" transmitter which you can plug into (say) the headphone socket of your TV: the transmitter then sends a signal wirelessly to the MiniTek (using a proprietary version of Bluetooth) and the MiniTek relays it to the hearing aids. Using either the direct-line input or the wireless transmitter works quite nicely, and there's no perceptible lag problem there.
I should have said, I've been onto Siemens tech support about it, and they're adamant that it shouldn't be doing this, and they don't know why it is. So I'm looking for a problem at the phone end.

i've experienced the same issues on various BT-Receivers and Smartphones. Seems to be a general issue. So far, this 1 second lag was present on all combinations of:
Phones: Samsung Galaxy S2 / iPhone 4 / HTC One
Receivers: Creative D100 / Creative D200 / Belkin BT Adapter
As i found out so far, this problem occours when the receiver can't handle the apt-x codec and audio has to be resampled to the older SBC codec. Found one thread kinda dealing with this topic, but haven't tried it out for myself at the moment. I'll do some testing later when i'm at home.

Hello everyone!
So last weekend I finally received this: LINK (EBAY)
I am totally new at Android Auto, though I have had several Andrioid Phones, as well as an Android tablet. Now I have an iPhone SE - so yes, I turned to the dark side. Not important here and now.
My question is - When I had both phone and tablet with android, I remember the many many possibilities I had with rooting etc. What do I have with my Radio? Can I root it? Can it be even better?
The only negative thing I have to say, is that the sound quality via bluetooth is quite poor - especially in the higher notes. The bass however, is still awesome on bluetooth. The sound quality is only bad on bluetooth - which tells me there is something wrong with the bluetooth hardware og the bluetooth software. Very sad to find out - I listen to bluetooth music 90% of the time. That issue let me to thinking: Is there a way to fix it? Maybe a root or something?
Also - are there some must-have-apps I should know about?
Looking forward to hear from you.
Thanks.
I have noticed the same, however it is not related to Bluetooth, the BT quality is fine, the sound quality problem begins when Android Auto is activated. Try using Spotify with the standard BT connectivity. Then test the same song with the USB cable connected and using AA. The sound quality is fully degraded when using AA compared to the BT quality. I Use Viper4Android and the drop in quality is even bigger since Viper4Android doesn't catch the sound stream.
Any idea out there?
By the way, I'd rename the subject of this thread since the sound quality problem is not related to Bluetooth but with Android Auto.
Same, don't think there's a way around it.

Second comment on that article, has to do with digital vs analog and our built in equalizer. You'd think digital would sound better

BT is also a digital stream and sound is excellent, even more when paired with Viper4Android. Nonetheless V4A doesn't seem to catch the digital output stream used by AA.
Maybe it's just usb? My thumb drive doesn't sound as good as my Bluetooth with the same song either.
Yea, audio is transmitted via USB, so in theory the quality should be even better since it is transmitted without the SBC compression like with BT (unless you have aptx). If your in-car has a built in equalizer i would advice to use that one

The theory is not working in this case, most probably because we don't know the root cause of this weird and annoying issue.
Car equalizer is not working when there are missing frequencies. BT works perfectly, but when playing the same song, with the same device and app (Spotify, music player, TuneIn) the quality is severely degraded when using AA. No deep bass and no treble. Total loss of both ends of the audible spectrum while BT quality is superb (compared to the crappy AA quality)
I have tested this issue with a Chevy Malibu 2017, Chevy Impala 2017, Ford Fusion 2018, Buick regal 2017 and Hyundai Sonata 2018. Same degradation when using AA with different head units, different apps, Axon 7. I hardly believe it is a device issue, I believe it is a problem with the protocol. Are you experiencing this issue? I am using RR ROM.
Just purchased a new Honor 9 Lite having come from a P10 Lite.
The 9 is a lovely phone in regards to its screen and shape but both phones have dreadful audio quality over bluetooth.
I cannot listen to music as anything with any volume (especially guitar based rock/metal) sounds like a 64kbps MP3 from 2000 napster .
I only a have modest quality Bluetooth headset (low end Phillips) but the quality is dreadful, equally my car stereo really exposes how compressed the audio sounds. A cheap Amazon fire tablet sounds superb in comparison as have my previous phones.
Is this just the way audio is with Huawei / Honor offerings? Seems such a stupid problem but its ruining my enjoyment of the phone.
Any ideas would be great before I get shut of what otherwise is a excellent phone.
I am also facing similar issue of poor audio quality over Bluetooth. Is there any fix?
I bought my H9L direct from their website when they had the offer with the free Honor bluetooth headphones.
The sound through them is horrible and tinny. There is a built in EQ mode called Histen, but it only works with wired headphones.
I think that if they had a promotion for own brand headphones, then they should at least make the experience worth while.
I'm very close to ditching the bluetooth & going back to a wired headset instead. Bluetooth in car car is also very low volume so I have to have the radio up really loud.
At the very least, they need to activate the Histen over bluetooth, aparently 3rd party EQ don't work
Use poweramp and see the magic (use pro version)
Hi there,
I replaced my HTC 10 with the P20 Pro and since then i have really poor audio quality when using my hands-free phone system over bluetooth in my car (Mercedes). The quality was good with the HTC and turned bad with the Huawei. I looked up the settings in the developer menu and saw that the BT coded that is used is SBC. When i turn off Bluetooth on the mobile, i am able to select a different codec but as soon as i turn on BT again, SBC is selected automatically again in the menu. Is there anything i can do to permanently select another codec such as aac or aptx? On my HTC, the option for following the "standard setting" is preselected.
facing the same issue with my Ford Focus. Sound is cracking, and the only way to fix it (temporarly) is to reset the connection and made new one. but only works for a few days, then it returns....
Also waiting for a fix, and even in the latest firmware version Cl20C432131 .
Nissan Note 2012
Same problem in my Nissan. I don't know what codec my old galaxy s7 used but the drop in quality when switching to P20 pro was huge. I also cannot permanently change the codec settings. This is a deal breaker.
You should remember that there is 2 ways bluetooth working with sending audio - in handset way (low quality but allows microphone input) and in headphone way (normal quality but no mic input).
Exactly the same issue as me in my Audi. I don't know if I'm glad other people have this issue but at least i know it isn't just me or a fault with my car haha!
People the other end seem to hear me fine. Its not practical to keep connecting and disconnecting each time i want to make a call in the car.

Interesting, I'm using android auto and I believe it switches between these modes automatically. With my old Galaxy S7 I could hear a real downgrade in audio quality when the phone was responding to my voice prompts. On the P20 Pro, the voice prompt responses seem much higher quality than the previous phone but the music is much lower quality - as if it is only using a single mode.
I'm not sure about 'no mic input' though, both phones could can hear voice prompts over the music (as long as I shout!)
Nevertheless I will test with google music only and disable android auto and will report back.
(for me the music quality is always poor even after reconnecting - it does not sound like it is coming over the voice channel, it is more subtle a difference than that)

Try connection with car audio in your phone with active option "media audio"
Thanks

Thanks, I tried this and it had no effect on sound quality, but......
I need to confess a stupid oversight. It turns out that my Google Music settings specified 'Normal' quality over mobile network. I set this to 'Always High' and restored the original quality of music that I was used to.
So it seems that:-
My car has always used SBC at 44.1 KHz 16bit
Even with this low fidelity Bluetooth connection, it is still possible to distinguish Normal and High quality modes of Google Music.
Hi folks. Just moved to a different carrier, we were previous Google Pixel owners, but our new carrier doesn't support them so we had to move to S10s.
The big complaint here is the horrible sound quality coming from the phones to all of our Bluetooth devices. Cars, speakers, living room sound bar. Static-y noises and what sounds like just a far lower quality across all devices than what comes from our Pixels which we still have. Our kids Iphones have no issues playing clean and clear either.
Really frustrating issue, we both use our music service daily and this is darn near a deal breaker.
Any ideas or solutions out there? I've searched high and low to no avail. Thanks in advance!
Anyone? No one else has this issue?
is your phone rooted? Is this a snapdragon or exynos version? If its exynos version, rooted, installed aptx bluetooth codec and viper4android for better audio
Exynos, fully stock here.
No problem with bluetooth audio.
US Snapdragon phone. Completely box stock. Bluetooth even connects at an audibly lower volume. It sounds almost like it's connecting through one of those old FM Bluetooth transmitters. It's terrible. I've fiddled with every solution I can find online for others suffering the same issue, nothing works.
Actually, I didn't want to root my S10. However, the sound quality via bluetooth is so bad that you cant avoid Viper4Andriod.
That was also the case with the S8. At the point Samsung has huge deficits.
Without root / V4A you just have lousy sound quality.
I'd really love to find a workaround that doesn't involve rooting, but if that's all there is.....
I had the same problem with snapdragon unlocked variant. The factory audio quality over Bluetooth was terribly bad. It was tinny.
Interestingly when i used "seperate app sound" feature it has improved. But not as good as exynos variant when i compared.
Steps to follow.
Advanced Audio setting -> seperate app sound -> Turn ON ( select the app and bluetooth device )
Let me know if it works.
Never did find an answer to this question. Found that when it's plugged into a 3.5mm port it's even more noticeable. It's got to be a software issue. The static starts as soon as any music begins, and ends on any song switch or pause. You can actually hear the static 'kick in' right before the sounds start to play. It's horrible. Doesn't do it on my backup phone, or either of my kids' iPhones. Just these two S10s.
Hey man, did you ever find a fix? all of a sudden I started having this issue. If I turn "Call audio" OFF it is fixed and the quality is great again, but with Call Audio on, its crappy, on my car, or headset, same behaviour.
The phone seem to be using the Call Audio profile despite no active call.
Did some more testing, if I hit on "Disconnect" on my car system, I get the "call disconnect" sound and after that the audio is great. The issue seem to be the phone thinking its on a phone call and using call audio profile to stream the audio.
