[Q] Poor Audio Quality & LPA - Verizon HTC One (M8)

Edit: A factory reset fixed it. Thanks anyway!
Hey XDA,
When I first got the M8 I was blown away by the sound quality. Much better than the G2. Convinced me to stay with the phone.
Then after root, s-off, other tinkering, the headphone audio quality sounded worse. Way worse. Vocals sounded like they were dampened by a thick blanket. The soundstage narrowed towards the center.
Installing V4A did nada, so I eventually tried setting LPA decode to false in the build prop. Day and night, it was back to the original amazing quality.
So my question: Did I just get a bunk phone? Besides the lowered power drain, are there any advantages to LPA? Does this reasoning even make any sense? :laugh:
Thanks!

Low Power Audio setting in the build prop. Viper 4 Android asks you to disable it after install.

[Q] Is There Any Way to Make Headset Volume Louder?

Hello everyone!
I got the S III a few days ago and so far I'm pleased with it. I rooted it yesterday and got rid of the Verizon crapware and it's even better! I do have one issue though. I often listen to music in my car, and for that I usually use my phone. I'm having an issue with it being to quiet though. All of my other phones and tablets have been loud enough, but the S III is just barely audible when I'm on the highway even on full blast. Is there a configuration file or something I can edit? I'm also wondering if it has something to do with the "Loud music may harm your hearing if you listen to it for a long time" prompt.
Thanks for any help!

That doesn't help me, I don't even have the galaxy 553 or whatever.
You could use Volume+ in the Play Store. Many GNex users used that for their lower than normal speaker.

I just tried it. It did nothing to the volume level. Neither quieter or louder.
I take it there's no way to do it?
Try this. Phenomenal sound. Read the op carefully for all the install instructions. Hope it works for you.

Try playing with it some more. I use the paid version and it works great at increasing the volume.

That prompt appears to be only a benign warning - happens when you have a plug in the headphone jack and then raise the volume beyond a certain point.
This phone's playback volume is good for me using the headphone jack in the car, for what it's worth.

I've been searching to solve this issue as well. Try awesome beats http://forum.xda-developers.com/showthread.php?t=1819353 (note: I just made a nandroid backup and flashed the zip and it works) in the awesomebeats app I set bluetooth tab(assuming bluetooth headset) I set beats boost enable and moderate, enable equalizer: preset: vocal boost, loudness compensation: weak or strong. It seems to make an improvement unless I'm just experiencing a placebo effect.
Just search volume+(volume boost), on play store a simple app to boost volume

Ok, so I really thought this would work, but once it hits a little over half way volume level (or the point where it starts saying loud music may harm your hearing), and I try to turn it up, it doesn't get any louder. Seems like it just increased the gain. Thanks though.
I'll try awesome beats next, I just don't need the bass so loud, I already have a subwoofer in my car. ^^
Volume+ is what you need I use this myself and it definately works, make sure to go into each of the settings speaker, headphone, bluetooth and check off audio modifications and use custom eq settings then slide your eq settings up. play around with the settings to get best balance. Bottom slider is volume boost.
I use my GS3 in my car and I don't have a problem. I run it through a horrible fm transmitter and it is still loud enough. When I plug it in at first it cuts my volume in half due to the headphone safety setting which I can't find to turn off. It was an option on my Droid Razr. I'm running the synergy rom on my phone. You can try messing with the equalizer settings depending on what you play your music through that should help. but it sounds like a problem with your radio or your aux cable you are using. Try it in someone else's car or a different cable.

Amazing. Exactly what I was looking for! THIS IS A GREAT SOLUTION FOR ANYONE LOOKING!
Thank you for sharing, it is indeed an improvement.
I'm just trying to find out whats draining my battery now though. Seems the "Phone" application has began to drain battery life, but it may just be a coincidence.

It's my setup. I'm using computer speakers and an inverter with a subwoofer to listen to music. It's all good now though. I found a great solution.

[Q] 4.4.1 Louder sound?

I just finally did the update to 4.4.1 and is it just me or does the volume for everything seem a bit louder?
Ya I just updated five minutes ago and I noticed the volume being much louder too, especially on the locking and unlocking sounds. That's a good thing though since so many people were complaining about the volume not being loud enough?
Still playing around with 4.4.1 but so far so good

Hi, do you know whether the headphone volume is also louder? Thanks.
And i thought i was the only one going crazy ahah
Yup definitely sounds louder now. Especially on unlocking screen and screen shutting off. Havent received any notifications to know if that is any different.
The audio is just more compressed, I did some tests in a previous post that showed that.
It averages louder, but isn't any more loud than before at max loudness.

Yes, it is louder. And it is not a placebo effect. I have two identical n5s, one on 4.4.1 and the other still on 4.4.
Definitively louder!
Plus an overall speed boost, went from antutu 28-29k to 30k on complete stock.

Aside from the camera and louder audio, i haven't noticed anything different
Camera is much better than before, though it didn't really bother me to begin with, but comparing the previous lagginess of the camera motion with my iPhone 5, it looks as though the 4.4.1 update made the camera motion smoother than on my iPhone 5. Video mode seems a bit equal, although I think the nexus is slightly smoother than the iPhone.
I really can't tell a difference in speaker. I need to test tomorrow in a more audible environment (its late and quiet here) it does seem a little louder, but I'm not sure yet. Some sounds seem louder, while others are just as quiet as before. Still pales in comparison to iPhone 5 speaker.
Haven't ran any benchmarks, but performance does seem slightly better as well. Ran a test lap on real racing 3 where I noticed obvious frame rate issues when I first got my nexus, but now it seems a bit smoother, much less noticeable lag.

Call volume with earbuds has gone from too loud on the lowest setting up to deafening. Not good.
I checked cpu spy, seems like it's boosting to 1.2ghz instead of 1ghz now.. Anyone confirm?

Stronger haptic too.
If I had to assume, I'd agree with you on the haptic feedback being stronger, bloot. But if it actually is stronger, its a very small difference. The motor doesn't feel any different than before, and I doubt a firmware update could make it stronger. But again, it does feel a little stronger.
As for the sound, tested it today and yes there's definite improvement over before. Still barely audible in some cases, but I'm comparing with my old iPhone 5, and honestly, the situations I'm comparing to are better suited for an actual speaker anyway, not some tinny phone speaker. So for most typical case usage, the speaker is pretty good now. Keep in mind the speaker isn't being touted as one of the phones features, much like a phone with stereo speakers, or higher quality ones. So with that in mind, the speaker on the nexus 5 is actually pretty good when you consider the price of the phone.

Also, Koush posted on G+ recently that the code for mirroring to a chromecast was also added to 4.4.1, so maybe we will be able to mirror to our TVs.

confirmed. it boosts there for ~3 seconds. too long, imo.
i don't think anything actually happened to the sound, hardware-wise. it seems like all they did was normalize the UI sounds to a higher level. my custom ringtones/notifications are still as quiet as ever
quite absurd that the notification led for missed calls still doesn't work

[HELP!] Really low audio when recording video (kitkat)

I switched from Sense to AOSP last week and while going back and reviewing my videos since then, I discovered that the audio is at a really low volume (basically inaudible unless you hold the speaker to your ear). This has been consistent across several 4.4 ROMs (CM11 m5, m7 and the most recent paranoid android) . Recording audio only isn't a problem, so I imagine it's not the hardware.
Is there anything else I can do other than switch back to sense? My baby daughter is becoming quite the talker and I hate that I don't have those moments from this week in a usable form.
I noticed that too but I may have been holding my hand over the mic.

Interesting... Would you mind reporting back if you notice it again? I know its not a result of covering the mic on my end. I wonder if there is an app like viper4 android, that boosts input rather than output.

Go into your sound settings and make sure UHQ Upscaler is off. Then go into Viper4Android and make sure its activated for bluetooh (it has its own section). You should be able to play with the sound now. Between Viper, Beats, and Dolby, you should be able to get it sounding right.
One thing I also found is sometimes the mods stop processing the sound, so you just have to toggle the UHQ Upscaler on and off again and you should be good.

Hey man, thanks for the tips. I gave it a try and toggled the UHQ uscaler without success. Its really the native un equalized sound that Im looking for. On tekxodus, the bluetooth audio sound is very hollow and weak. After I switched to a different rom the full sound came back again. oh well, win some, lose some.

Sure thing, man. When I was on that ROM I found that the audio was very bad unless you go into the mods and tweak them. The problem was, I have a Tasker profile that reboots my phone every night while I sleep, and none of the tweaks I applied remained after the reboot, so I had to go back in and redo it every day. It became very time consuming.
There's a thread in the MODs section that tells you how to get Viper working on any ROM and now I've go the best of both worlds. Running Darthstalker, Arters kernel 11 and Viper. It's glorious. Bluetooth and all.

I think it's a conflict of all the sound mods trying to run at once. On the last few pages you'll see a few posts about it and a mod that makes them all run in glorious harmony.

Nobody is actively porting audio mods anymore. Except for DTS I suppose.
For now the goto is to use Ainur Sauron or Narsil and/or any of Viper, JDSP, and DTS.
Obviously when it comes to audio mods, less is more though. Too much signal processing is detrimental to the audio quality and generally makes it sound worse. So I'd suggest only using one of the DSPs with one version of Ainur at most.
But in my experience the 3a(xl) doesn't really need any audiomods. The ****ty earbuds I got with mine along with decent quality audio files is more than enough clarity wise. I also got a new pair of true wireless earbuds (Liberty 2 Pros) and they sound phenomenal.

The Pixel 3a sounds very good. But with viper I can simulate a wider soundstage on my Bluetooth earbuds, and they sound way better than they deserve. I have a pair of soundcore liberty 2 that are bass heavy, even with the Anker app. They give you many presets, but not a custom one, go figure.
About Dolby Atmos, I realize that two apps could over process sound, but on my Galaxy S7, I had a pretty good balance. Plus I like to experiment a bit.
Thanks for the info btw
Not sure if I did something wrong but this obliterated my battery life. I went from 9-10 hrs screen time to 3 1/2.

No battery issues here.
In fact, the only problem I have is that sometimes viper stops working and I have to restart the phone.
I have no mods/modules installed other than viper4a.
