Could anyone with the phone double-check their bluetooth codec options?
Being Android 8.1.0, it should have LDAC ... and that is extremely important to me. But it's missing from my phone. I have tried installing JamesDSP through Magisk, and it works, however I do not see how to enable its LDAC so its running everything through SBC or whatever that low-quality sounding codec is called.
Thanks.
Brian
I also wondered if such audio drivers like LDAC enabling is similar to having 4K 265H codec built in to the chipset & not a question of software updates can enable.....

Hi everyone,
Android O brings bluetooth audio codec option that includes AptX. Does 625 actually support AptX? Is there a way to verify this? I have an AptX ready headset, it isn't fancy by any means, but I intend to make use of the feature. It's probably gimmicky but let's give it a shot.

This is screenshot of connected devices in action.
@sanctitude:
Which app does the notification about runnig "BT aptx codec" on your screen shot come from? How can i show that on my device?
You can find it on developer option, scroll down to bluetooth section where you can select your codec
Thanks, santitude!
I know about the "developer option" for the general setting of apt-x for BT but this is not the same thing as your screen shot.
Your screen-shot above is apparently a notification about the "running" codec, being actually used at the moment of playing music through BT.
On my device on LOS 15.1 i do not see a notification as on your screen shot, but this is exactly what i'm looking for.
I'm on stock Oreo, the notification just showed up during playback using aptX headset, it's probably OS related or behaviour. Anyone using LOS, please clarify
Hello,
So based on my request for help in the following thread, I was initially trying to setup ultimate audio experience with ARISE (not only V4A) to run on stock 8.1 (Mar 18 updates). However after numerous tricks and ways to make it work , i reliazed its not possible for now. I also came to know that V4A and Atmos dont live together well and Atmos overrides the sound processing by V4A, which has to be manually reactivated time and again.
https://forum.xda-developers.com/pixel-xl/how-to/guide-ultimate-audio-battery-guide-t3727124
I reverted to Android 8..0.0 (Oct 17) and then following the guide in this thread
https://forum.xda-developers.com/pixel-xl/how-to/guide-how-to-install-arise-sound-8-0-t3692415
I was able to install V4A , Dolby Surround to work together (Arkamys , A3MD crash repeatedly and ICESound breaks the sound at all from speaker or headsets, didnt find a solution for it so far).
One of reasons for me to try Google Pixel with 8.+.+ was to try the new (supposedly) hi resolution bluetooth codecs namely AptxHD and LDAC (a Sony version of Hi-res audio protocol).
Being an amateur audiophile, I bought Sony Wh1000MX2 which supports both LDAC and AptXHD.
A finding which I made was when I paired the XL with Sony Headphones using LDAC, the audio quality was good, however I wanted to make it better by activating V4A and Dolby Surround audio mods. After fiddiling for a couple of hours, I realize V4A and Dolby does not work or recognized the sound output when the headphones were connected using LDAC. It was seen as the V4A driver status showed "Abnormal" and no "Processing" was done. However with the same setup as soon as I changed my bluetooth audio connection to use AptxHD , the V4A and Dolby started working and sound was equally superb with the added value of tuning it more to my taste using the audio mod.
I am not sure why the audio mods are not bluetooth connection protocol agnostic, or why not working with LDAC.
Shared it for information, maybe the gurus would be able to reproduce the setup and post a working solution.
Thanks.
Hi, same problem here. I have a pair of Sony MDR 1000x Bluetooth cans with ldac support. Flashed my Xiaomi Redmi Note 4x to LOS unofficial Oreo to get the ldac codec going (it works indeed), but v4a does not work with this codec. If I choose the SBC codec, it apears to at least realize that it can do something (although changeing effects dosent work). With ldac enabled v4a driver status says abnormal and obviously nothing works. All in all I guess that we cant do anything other than wait, so that some devs will adopt to the new features of Android Oreo.
Hope for the best
PS: sorry for possible spelling mistakes
edit: if someone needs logs, im happy to provide them.

Not the type to necro old threads, but I believe I've found the solution to your problem. I had this problem myself on my V30 and realized what was making Viper effects not processing. LDAC by default starts off with an audio sample quality of 96 kHz and 32 audio bits per sample. If you can change these settings in developer options, lower the sample rate(sample quality) to 44.1 kHz - the rate used for 90% of all music & audio and the bits per sample to 24. Viper audio effects should work now with LDAC. You will have to do this every time you turn on/pair your headphones to your phone.
Ypu can use James DSP for ldac codec with any sample rate and bits per sample. James DSP has a magisk module and can be installed from magisk.
To preface, on OxygenOS 5.0.x/Android 8.0 we were provided with additional bluetooth codecs and additional setup for bluetooth codec manipulation in Setup>Advanced and Setup>Dev Options. In OxygenOS 5.1.x/Android 8.1, the Setup>Advanced options were removed. I'm currently on 5.1.4 on my OP5.
That out of the way, I'm trying to validate if anyone else is experiencing an issue that I'm having. I have a set of Bose QC35 bluetooth headphones that support the AAC bluetooth codec, support of which was added to the OP5 with Oreo. In OxygenOS 5.0.x, I had no problems with it. In OxygenOS 5.1.x, it will only connect with AAC when first paired. If I turn off the headphones and turn them back on, when it reconnects, it defaults to SBC and will not switch back to AAC unless I unpair and repair the headphones.
Does anyone else have Bose QC35 headphones that can confirm this behavior? Or perhaps another set of headphones that support AAC? I've tested with a pair of headphones that support aptX and it keeps the codec, so it appears to be either an issue with AAC on OxygenOS 5.1.x, my headphones, my phone, or Android 8.1 in general. Any validation would be helpful. Thank you

in the open betas the advanced bluetooth options are still there under developer options
can't help you with any of the other queries as I use apt-x HD
I'm pretty sure nvidia took the codecs out of their releases. I have a pair of nuraphones which supports apt-x and HD. I have a note 4 and aicp and everything works perfectly, the shield..AAC or SBC codec.
This is a magisk module from a Huawei to add the support

I tried installing another zip and I got slow motion video and audio stuttering. Anyone else have any insight on this?

No, since otherwise, your headphones wouldn't work. You can't use AptX HD on a headphone that only supports AAC or SBC. If your headphones support both AptX and AAC, the system will let you change that. The same goes for the rest of the settings. Every BT headphone supports the SBC standard, headphones that are Apple branded (AirPods, Beats) and others use AAC and higher priced BT headphones with Qualcomm chips support AptX (HD) and AAC. Higher end Sony headphones use LDAC. All of these support the lowest quality standard SBC. There's absolutely no need to any of these, since it would just break things.
