Bluetooth audio quality downgrade after EMUI 5.0 update - Huawei Mediapad M3 Questions & Answers

Last night I updated the tablet to EMUI 5.0 and after that the system did the update to 351. Bluetooth works fine as far connection goes but once you played any media stuff like music or youtube the audio sounds like an fm radio station from the early 90s. The audio has a very flat sound to like it you were streaming at a very low bitrate. Has anyone noticed this too after doing the update or could it just be a bad update. I'm hoping it's just that but wanted to confirm here with anyone running EMUI 5.0 how's their bluetooth audio. I used poweramp for MP3 but even poweramp can't improved the audio quality from bluetooth. The same bluetooth headphones sound way better on other devices it's just the tablet. Enabling SWS doesn't help if anything sounds worse.

no audio over Bluetooth for movies - Plantronic P590

anyone else get this? I'm ok for all other audio on the headset. phone, lastfm, fm tunes, mp3s etc.
I noticed this yesterday playing netflix through the bluetooth stereo in my car. Music audio came through just fine, movie audio played through the onboard speaker.
It is a known issue/problem. Hopefully will be fixed during next update.
That's great. I was speaking of specifically porting to BT headphone from a mp4 file on the device

Stutter when playing music over Bluetooth A2DP since 2.3 update

Hello all,
I've noticed that since the 2.3 update, I get a lot of stutter when playing music over Bluetooth A2DP. This is the same issue that is reported here:
http://code.google.com/p/android/issues/detail?id=15189
Anyone else found the same? Any thoughts?
Not sure if this is related, but I have the Droid 2 with 2.2. Most of my mp3's played great via bluetooth (on the Motorola headset (S9-HD)), however, there was always a few that would stutter consistently. After trying nearly every suggestion out there, I found that when I unchecked the ENHANCED STEREO option under the bluetooth settings, the stuttering stoppped. Unfortunately I did lose some sound quality.
Ive always had this problems with bluetooth A2DP, iphone and DHD, never been able to fix it either.
Playing through my Kenwood BT head unit.

Bluetooth poor sound quality

Hey p8 lite owners,
I have noticed that when playing audio/ music via Bluetooth to external speakers the sound output is extremely distorted & too "bassed". No issues with connection just bad sounding music.
Am rooted on marshmallow, unlocked bootloader. Anybody know how to fix the Bluetooth audio quality? Shame. This phone has a nice set of inbuilt speakers.
TIA
Issue seems to have resolved itself after a while.
What version of firmware are you running?

Bluetooth Music Quality

How the does bluetooth sound for you guys? Mine seems to be worse after the B29 update (not for certain that's when it degraded). I have a decent car stereo setup, but bluetooth distorts and crackles in the mids and highs. It's not unlistenable, but I thought my stereo was on the fritz until I used my 3.5mm input from the headphone jack, which sounds just fine. It can't be that the DAC is that much better, as my other phones sounds fine and this used to.
Do you have any thoughts or experience with something besides a small bluetooth speaker?
And I have tried playing with the Dolby settings. They make no difference with the distortion.
After some perfunctory tests I have noted that Bluetooth audio seems to introduce a significant amount of extra noise at high volumes. Aside from the additional background noise I have not noticed distortions with Bluetooth yet. I have only checked this on B29.

Just something to try...I have a BT device hooked to my AVR, and when I stream through that, if I have the volume on my phone up it sounds horrible. If I stream through it with the volume up just 1 click of the volume button, it sounds good. I increase volume at the AVR instead of the phone.
Through Bluetooth hands free working flawlessly to my.(A2017G version)
I'm having 2 LG 1100/2 Sony SBH 80 and 2 SBH 20.
Haven't try it with external speakers(since I don't own any kind) and on my car I'm using the handsfree and not connected to the car audio system.

I have a A2017G on B05 and a somewhat cheap aukey BT headset: it seems to sound fine for me, no crackling or hissing. Have you tried it on different devices to compare?
A2017U on B29, using Jaybirds Bluebuds X, the sound its great, no distortion or cracking.
I use the Bluetooth on my car stereo too and the sound is excellent. No dolby, but the equalizer works fine.
Did you verify that all your bluetooth devices supports aptx? if not then you will lose sound quality :S
idk, i dont like bluetooth audio streaming... even with aptx. Its not bad but if you want to steam flac music it will still limit the quality. Somehow if i stream the music via bluetooths aptx it sound flat not dynmic and
voluminous.
I haven't tried it with the volume just below full. I'll give it a shot in the morning on my commute.
Other devices (S5 and 6P) sound just fine when paired to my headed unit, so it's likely something with my Axon 7.

Quick test with the volume just under full seemed better. I'll know more after a drive tomorrow. Thanks everyone.

EQ on on your car stereo or phone? I don't know of an EQ on the phone (maybe I've overlooked something).

On the phone. I meant to say that it's not using the HiFi audio, but the Dolby eq it's fine on Bluetooth. Sorry for the confusion.
I think it sounds about 95% better just one click below full volume. I never would have thought that digital Bluetooth volume would have been the problem, having always set it to 100% with every other device. Thankfully, Tasker makes for a quick fix.
Thanks for the tips and feedback, everyone.

Bluetooth on Android O Beta

Hey all,
Ever since opting into the Android O beta, my Nexus 6p has been working fine, except for connected to my car via BT. It connects, but just shows 'Unknown Artist' for any kind of track info, and if I switch playback apps (for instance, from Pocketcasts to Google Play Music), my phone disconnects from the car for a second or two, connects again, and still doesn't work. The car in question is a 2016 Mini Cooper S. Anyone else seeing issues like this? Works fine on 7.1.2.
ive got the same issue vw polo. audio plays via bluetooth but no artist info it just shows im connected to 6P and skip track controls dont work just mute and volume
Yeah, I don't even get audio. Nothing actually plays, car displays "unknown artist".
I have this as well on a 2017 toyota, calls etc work fine, just music dips out

Thanks for the setting tips, I'll try them out tomorrow and report back.
No luck, same issue persists. I even tried usb-c to usb-a, but my Mini doesn't recognize it as an audio device that way Time to get a new head unit possibly.
No luck, still 'unknown artist' and no audio, even though my phone thinks it's connected and playing.

Do you have this issue on 7.1.2 as well? Don't forget Android O is still in "beta" and I wouldn't be surprised if the BT is a little screwy still.

Everything works fine on 7.1.2, I had to decide what was more important: working car audio or a much faster OS experience. Hopefully this is something that's either fixed in the release of O, or something my car manufacturer can patch into their system.
Not sure if this will help but my car seems to have pretty good luck with this technique and BMW/Mini ICE systems are similar. I use the aac codec keeping everything else default. I've had the issue a well where it's playing on my phone but not the car; the info also doesn't show. Restarting the phone right before starting the car or soon after seems to be relatively effective as it would then connect after the restarts and actually play the music correctly and show the info.
Not the best solution but hopefully this ends after the final is released.
Hi! I hope this helps. It seem like changing the setting (unchecking) for AAC audio helps with the issue. This seems to be a new feature in Oreo, so go to Bluetooth settings and in the little gear next to device it will popup with a couple of options, uncheck AAC.
