Today i received my new HTC Touch 3G rom: 1.40.405.3(21259) (10/24/08)
The playback volume is very low. Compared to the Viva model of a friend it's about 50% low.
It looks there is no way to boost volume level using software.
What do you think of volume level of yours Touch 3G?
Are you talking about speaker volume or headset volume?
I almost never use speaker to play music but it seems loud enough and with a headset the volume goes pretty hard(above what is safe for your ears) so are you sure you've got the volume set on maximum?
There is a thread
there is a trhead about boosting music and works for me there are 2 types of boosting the light and max .cabs here is the link

I'm running the latest cm10 nightly with the stock kernel and the volume of YouTube videos is extremely low, this also happened with the previous nightly from about a week ago that I was running. Even with headphones in I can barely hear the audio, yet the volume of everything else is fine.
Has anyone else been experiencing this?
I flashed Cookies and Cream v1.3.1 and the volume is audible (but pretty low) but with headphones or an external speaker plugged in I can't hear anything.....
is it just YouTube in general? or all audio.
i'm on CM10 monthly-2, and some YouTube videos have low audio in general, with or without headphones.
but then my music and videos i manually put on it have fine audio.

When playing sounds or music at very low volume there is an interference noise that can be heard if you put the ear next to the speaker. I've tested it with the game Mystery Room. It's very annoying when you are on a quiet environment.

Another thread in xda: Static / buzzing from speakers at low volumes
siraltus said:
It's because the Nexus 7 uses a crappy digital volume control that simply reduces the volume of the digital waveform before it hits the DAC, instead of having a real analog volume control -an op-amp that adjusts the volume of the signal before it hits the headphone/speaker amplifier.
What you're hearing is quantization noise as at the lowest volume the audio uses only 2-4 bits of dynamic range instead of the full 16 (or 24, dunno what DAC is in this thing). It's the same as the bit-crushing effect you hear in some dubstep and other electronic music that degrades the audio into a robotic crunchy mess, only here it's not on purpose, it's just cheap design.
There is nothing you can do about it.

Great job mod!

Thanks for consolidating everything and giving people an easier way to learn about this issue.
The best way I believe to produce the static.
Play YouTube Video > Adjust volume to mute > Listen to top speaker (portrait mode) > Then gradually increase it from mute and up
I was at a BestBuy and I was still able to hear it, the Aug/Model I bought and the floor model they had, both have the static.
First I need to add that I find the so much advertised two DACs of the Axon very highly exaggerated in terms of power. They are just too weak, even compared to my previous Note 3, both on headphones and speakers.
Second, they seem to not be able to be effectively used on almost any app since 98% of apps do not utilise them by default and one cannot change it.
If you tweak Dolby Atmos a bit you can get it to amplify the general audio output, both on speakers and headphones, and this is why I use it predominantly. I am on the B09 update on A2017G and it is still very buggy. No matter what setting I choose, i.e. Music, Voice, Game, Custom, when I leave the Dolby Atmos screen it drops sound for a second and always resets to Movie, no matter what. Also the sound regularly interrupts, especially when unlocking screen or doing things in the background, or just on its own.
What annoys me most however from when I bought the phone is that at very low or low volume (only on speakers), when there is speach or the music starts, there is some kind of hissing, ss/sh-ing sound corresponding to the words said or the tiny beats of the music played. It's like a background noise added on purpose simultaneously with special, mostly high frequencies, i.e. words, tiny/starting percussions or similar, no matter the Dolby Atmos setting. This noise stays apparently at all times, it just is not heard when more, mostly low and middle frequencies get in. This "noise" is not available when no Dolby Atmos is used, however the volume then drops by a few levels down. Good or bad, Atmos also adds some spatial effect to the sound, which is why I like it for...
Does anyone of you, an A2017G or A2017U user, observe similar behaviour on your device? Is Dolby Atmos working better for you, i.e. unconditionally steady settings, no low volume added speakers noise, no sound interruptions?
I also noticed browsers do not get use of the DACs/Dolby Atmos, i.e. YouTube, online videos, many video players. My favourite before Aimp was unable to do so also so I had to transfer to Jet Audio and PlayerPro, both of which can work with the Dolby.
Why did ZTE add (two) DACs when they couldn't be used by 95% of the apps and games by default and even manually, also there seems to be no gain in output at all? Was this the case with the Lenovo Phab2 Pro's Dolby Atmos? For the "regulated hiss" (not present on headphones at all) I cannot currently watch any movies on the phone with Dolby Atmos enabled, unless at very high speakers volume. It hisses so badly every time a word is pronounced or some subtle 'invisible' sound plays. The same is with playing music...
I dont use Dolby when I listen to music - it makes everything so much worse and much quieter. Listening to flacs on stock music player with Super HiFi on. No hisses on low or high sound levels. Silence is silent. as for speakers - no hiss also.
ZTE did not add 2 DACs for music, 1 is for music other one is for audio recording which is records at 128kbps. and quality.. I dunno it's quite clear, I had recorded a room full of people, with two girls singing and some people chatting in backgroud and I can hear everything. but sound itself if on the lower end, girls vocals are lower than they are, everything seems shifted to lower sound spectrum.
Tooks some time and checked spectrum of that sound file 50-2000Hz. everything over 2kHz is just a noise.
and a little edit: it records nothing less than 50Hz - total silence there.
The stock player is OK but it's lacking on features, also not sure if it can play video.
I have noticed the low volume speakers "noise" with Dolby on when watching movies using almost any player - VLC, BS, MX and more. If I go above 30-40% volume it seems to disappear, but more like you don't hear it and it stays. I say "noise" but it is like a hissing/ss-ing sound added to sole frequences only, i.e. speech only or single instruments. When more frequencies get in, you don't hear it. Weird these don't exist at all with the Snapdragon amplifier, i.e. when Dolby is off.
https://community.zteusa.com/thread/12853, here is a similar thread in the ZTE USA community. I believe it has something to do with the Axon's own amp or its software and happens at low volume only. There was a thread in Reddit exactly about what I am reporting but I can't find it now.
If you go to your phone's Music\Settings\Dolby Atmos app, then move all sliders up you will notice that it significantly increases the overall volume when Dolby is on. So it's not low, if you change it, it boosts up the volume by at least 30%. On another note, the Axon's mic recording quality is quite poor/muffled, even compared to the old Note 3, hopefully they will improve it at least a bit by some future update.
I bought the A7 exclusively for its audio capabilities so am disappointed that I have to report insufficiencies in this exact area.
Does your Dolby Atmos set itself to Movie only if you exit the Music app? Are there any drops in sound when it's on and you do something in the background?
There are two DACs. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". So AK4961 works in standard mode and AK4490EN in Super mode. ADC is only in AK4961.
You can consider rooting your device and install ViperFX or the whole A.R.I.S.E. sound system. That will solve all the problems with sound output. However the sound recording filtering is surprising, leaving only the vocal spectrum is not normal. There should be a setting somewhere.
I have the Chinese A2017 model running Oreo & have just noticed this hissing sound which can be heard at lower volumes when I keep speakers close to my ear. I don't hear any hissing sound using headphones. I wonder if it's always been there or it's a hardware/software issue. I'm probably gonna hard reset the phone to see if it goes away. Anyone could fix it?
Hi, I was using CRDroid (android 8.0 version) for some months before I switched to stock marshmallow rom recently.
The following issue is present In BOTH THE ROMS.
The volume levels of the speaker are very weird,
While browsing instgram some videos have excessively low volume while others have decent while some have good audible sound
Before u say that it's the users audio quality let me tell you that I compared the same videos on my cousins iPhone 6s (which has a mono speaker) and audio levels on all the videos were quite audible.
Even my YouTube and Spotify plays at very low volumes.
I used to think my speaker was damaged but then how can I explain the high volume instgram videos???
Mx player allows me to playback videos at high volumes with the help of its sw decoder but what about the rest of the places? :/
Can anyone shed some light on this???
