When stock, unroot and unmodded, bluetooth playback to my Logitech Mini boombox and Motorola S10-HD headphones was decent. I did notice a few pops and clicks every so often, but nothing like what it is now that I have rooted and flashed the latest ViperXL stable ROM, ElementX 5.2 kernel and the German 3.17 radio. I've seen a few scant reports of this same issue, but I'm guessing not many stream audio via bluetooth, hence why the issue doesn't get as many mentions as it should. I can confirm it is NOT a hardware issue as the streaming of audio via bluetooth was fine on the stock AT&T ROM. Base ViperXL emitted this issue before ever adding the ElementX 5.2 kernel or flashing the radio, so I'm thinkin' the issue may be with ViperXL.
The static/crackling/popping sound is unaffected by volume changes. Turning the volume all the way down allows for only the artifacting to be heard and turning the volume up doesn't increase this sound, but at least puts the music on part with it so that you can at least drown it out with other ambient noise. It's horrible and only stops when you stop playing the audio. It sounds like clipping that occurs when an equalizer is set too high for the DSP or output device. Is there something written in these ROMs to alter the stock levels? I'm not talking the EQ options such as BEATS, Dolby or Sony Xloud 'cause toggling those on or off have absolutely NO effect on this issue.
I did come across a few posts in the ViperXL thread claiming to disable some chinese variant of the Dolby sound enhancer, but that functionality seems to be gone with newer versions of the ROM, such that I am now on. Disabling ALL sound enhancers does not resolve the issue. I know there's others out there havin' this problem. What would it be in third-party, sense-based ROMs that would cause this issue to exacerbate? Please post your experiences and possible resolutions.
Flashed 2.20 RUU and the issue went away. All signs pointing to the ViperXL ROM...
UPDATE: Issue didn't NOT resolve, but lessened under stock ROM. I've isolated the crackling to fluctuations in CPU clock. When locking the speeds to one clock rate, the crackling goes away. As soon as I allow the governor to adjust speeds, the crackling recurs. I'd really like a dev to chime in here and advise how this could be resolved. I'm going to flash back to ViperXL to see if these same variables have any effect.

I installed Tweak 2.0 coming from stock and had serious issues with audio. I re-flashed wiping data and the problems still persisted. I am getting audio skips when listening to music and I also had bad high pitched screeching noises. The audio was just plain "flat".
I flashed back to Eclipse with AOSP apps and the music was back to crystal clear with no skipping at all and the music was back to the "full" sound I was used to. I listen to a lot of Pandora in the car as I travel frequently. I also have the voodoo sound plus app to correct the low audio gain common with Samsung phones.
I get better battery life on Tweak and would like to stay on Tweak but can not live with the audio issues I was having. Does the audio get processed by the ROM or Kernal? I am using stock kernal for both.
I can not figure out what the problem is with Tweak Rom.
You don't have dsp manager ruining as well do you. I had to uninstall it when I can from eclipse to tweaked because audio issues.
Sent from my SCH-I510 using XDA
When I went to Tweak, it was a fresh install. DSP manager is included with Elclipse ROM, not Tweak. It was not even on my phone at the time.
Running Elclipse, I leave DSP manager off (all settings disabled).
Haven't heard of this one before - have you tried just using the same apks as are used in Eclipse? Audio has never been an issue, though I haven't used much beyond the play music and pandora apps myself.
Another thought - have you tried it with and without voodoo sound plus app being installed?
Hey Dwith,
No, I have not tried just the Eclipse Apps, I would not know where to start. In regards to the voodoo sound app, I can not listen to audio with my phone without it. It does not put out the correct audio output or dynamic range. The sound level is just too low without voodoo.
One would probably not notice if they are connecting the phone to a boombox or something small but when you connect it to an aplified home theater system or an aftermarket car audio system the difference between voodoo and non voodoo with the droid charge is like night and day.
I am pretty new to flashing ROM's and such so I am sorry if I can't troubleshoot this more. I was hoping maybe I was not the only one with this problem and others would chime in.
I really like Tweak but I can live with Eclipse too. They are both great ROMS.
Every time I activate any of the features/processors in Noozxoide, I can hear a slight static buzzing noise in the background of any music. When I turn off the features, the buzzing goes away. Is this normal, and if not, how can I stop it? I've tried listening to my music with Poweramp, Neutron, noozy, and jetAudio. My device is a Verizon SGSIII running the latest version of PACMAN ROM. My kernel is the latest release of KT747. I have done some undervolting and overclocking using KTweaker. I also have Ac!d Audio Mod v5 (the Samsung optimized version) installed. I have good headphones (Audio Technica ATH-M50s), so I don't think it's a hardware issue. Any and all help is appreciated.
Problem resolved, this post can be deleted.
May I ask how you resolved the issue? I have the exact same scenario going on with my sgs3 as well - I'm on a different ROM/Kernel, but same base issue. Thanks!
Hey everyone...I'm fairly new to flashing ROMs and Kernels onto my trusty dusty TF101. I've got the EOS4 b93 JB 4.2.1 with Kat Kernel lidpatch 80b. Unfortunately, I'm having an issue where my sound disappears and it won't come back without a reboot...and after that, it is hit and miss how long it'll last.
I've installed KAT Audio v1.24 but I really didn't find it as useful...other than the sound reinitialization button being available. I adjust my volume often and found I was just fighting the app to change my volume. I use my tablet as my alarm clock so toggle the volume modes via Audio Manager Pro...from Regular to Mute. My Mute setting has my alarm volume up so I can obviously hear it when it goes off. Sometimes I listen to things through the speaker, so the volume needs to be at my default setting...sometimes I listen with headphones and I lower it... The Kat Audio app caused all sorts of issues and I just couldn't figure out how to use it when I want to change my volumes. (much respect and appreciation for Tim Duru for taking the time to come up with a very powerful app for the community).
So...sound is important to me and I'd like to be able to control it, use it, etc. Is there a kernel that has better audio chip support that doesn't cut out? I've heard Guevors worked better for people, but am unsure if I can flash it over my current kernel. Any advice in this area would be much appreciated.
So, strange question and I might be asking for the wrong thing.
On OOS with viper (tried all varieties) if I have viper on over BT headphones, and the volume is above 80%, anything remotely bassy clips like hell and I get quieter volume during that point. I never had this problem with any older phone that wasn't OnePlus. If I used a custom os like Lineage on my old OP5, the problem never appeared. I use the aptx hd Bluetooth codec, but turning that off makes no difference. If its the Bluetooth stack, maybe its possible to port the Lineage one to OOS? I'm not sure what exactly it is, but if anyone has an idea, I'm open to it.
I like OOS and would like to stay on it, mainly to maintain my safetynet and stability.
Edit: The effect I had on if either dynamic system, or viper bass, both at minimum settings. Worked in my old phones that were not oneplus
Have you tried the viper in xxnolimits? I had the same issue with other vipers on oos but using this one I have no issues with clipping. I don't really use dynamic system with my headphones because it doesn't really add bass, but just lowers the volume of everything except bass. This was the same on aosp as well, and I did just test with the included no limits viper and got no clipping.

In fact, I did, it was the best copy of viper I had seen. It only seems to be with oneplus phones on OOS. When I use aosp/lineage I don't get the problem. With xxx, the effect was a lot less clippy, but because I sometimes have my music up at 100%, like on my Bluetooth speakers (it's a big one), it's still noticeable. It's like the OOS audio stack, or Bluetooth drivers or something have something to do with it.
The only other thing i could think of would be to modify the audio mixer file to raise the volume, so that the current 100% volume is now around 80%.that might also solve it but I have no idea where to begin
The best thing I've found so far is to lower the output volume on viper to -3db to fix it, it's not perfect though
I'm posting this based on my testing on various sources that the ZF6 sounds with my 3.5mm earphones sound different than my laptop, desktop, and galaxy S7. Desktop, laptop and my S7 sound identical.
Any rock song seem to be overly muffled on the ZF6 on my 3.5mm earphones and I can't seem to fix it. I have tried testing with various settings in AudioWizard and also tried disablling it to no avail.
Not sure if it was like this in Android 9 and also in Android 10.
Anyone else notice this?
I don't have any problem with audio. Have you tried another media player? I use Poweramp.

Tried different media player, youtube, twitch. Everything sounds off on the ZF6 compared to my mentioned examples.
Can you elaborate more about what exactly makes it sound off? Weird frequency response, some kind of sound effect, distortions/cracks? I will try to compare my phone once more.

Sorry, English is not my first language.
As far as as describing the problem, there's no inherent "problem" with the sound per se, but most songs I listen to on a daily basis sounds very different and off in a really bad way. I've disabled AudioWizard, and also tweaked with the equalizer, bass, treble in AudioWizard and nothing.
I've kept my best in keeping everything same for testing. Like, listening to the same song, using the same earphones, and pretty much tried my best in keeping things in stock settings and same across my laptop, desktop, s7 and zf6 as best as I could.
I think there's some funky equalizer setting that is muffling certain "tones" in music and I can't access it or something. I have no idea.
Not rooted/locked bootloader if that makes any difference. No funky app or add-on that could possibly affect this.
Edit: try listening to this: https://m.youtube.com/watch?v=3x8geNo31yg
the first 30 seconds sounds so obviously different to me. If this is not the case for you then something is wrong with my zf6 whether by some setting or defective
I can't hear any significant difference between my Zenfone 6 and a Acer Laptop without EQs. The music is quite old and not a high quality one but other than that everything plays fine.
Hi,
I do not own a Zenfone 6 but did own a Zenfone 5 last year and listened to a lot of music. I was coming from an HTC 10(the brand I went back to).
I did experience issues with the sound quality on the Zenfone 5 both on the external speaker and through headphones. The problem being an eq setting (which I had no power over) that lowers automatically the volume when low frequencies (any kind of percussions or beats) played fom either a music player or streaming app. The result was a "wavy" sound where volume fluctuated in a noticeable way, plunging down when low frequencies kicked in (I guess it's a way to stay under a certain maximum dB level?). The rest of the frequencies sounded muffled and blended together. Basically there wasn't a good sound separation even through the headphone jack.
No setting on AudioWizard could solve the issue and it was widely reported on the ZenTalk forums.
I remember a software update which claimed to solve the problem but simply ended rising the max volume through the jack, mantaining the sound distortion as it was. I found no solution whatsoever and switched brand.
I don't know if this problem changed on the 6 but what you describe sounds to me almost exactly what I experienced on the Zenfone 5.
It sounds like there was an output limiter of some kind which was altering the sound to avoid speaker distortion. I didn't notice this on my Zenfone 6. I've never had an Asus before though.
I had several problems with the audio from the 3.5 jack after updating to andoid 10, especially with the fm radio. I had to downgrade to android 9 to fix it.
