Scratch sound on speaker with low volume - Asus ZenFone 3 Zoom Questions & Answers

I didn't noticed this before, so I'm not sure if its due to the Nougat update or its just the "normal" way the speakers work.
I was watching youtube and the phone sounds ok when the volume is set above 40%, after that its to loud to notice the "scratch" sound I hear when the volume is really low (on speaker, not headphones).
Has anyone noticed that? I don't think is a big deal since it's rather unnoticeable in normal conditions but I wonder if it's just my phone or what.

Lower quality speaker. It is a budget phone after all.
You can download a sound equalizer and play with the frequencies a little to see if you can tone the frequencies down a little that are causing the distortion.

Yeah, I find it hard to believe its a budget phone, for me it's an expensive phone :angel:
I should point out that the only way to notice the scratch sound is by lowering the volume and placing the speaker close to the hear (I know, not healthy right?)

Volume Seems Week

I find that the overall volume on the Treo Pro is not strong. When listening through a speaker or even sometimes through headphones.
Now I realize the quality of the recording is a part of it, but frankly for many recordings i can listen with the earbuds on and cranked to the loudest and its still not that loud.
Anyone know of any tweaks to increase the volume out put? I really would love the built in speaker to be louder.

i dont know any tweaks, but i had the same issue, i even called tech support to get a diff phone swapped out, the tech told me to take the plastic piece off because it covers the speaker hole on the screen.....lol....i know how stupid! other then that i dont know anything to make it sound louder besides the keys on the sides to turn the volume up and down. I did notice that the speaker phone gets louder if u have the phone on a table or something. if this info didnt help then sorry for my worthless post...lol
Did you try removing anything covering the speaker? Yes not a fun idea, but if you did, did it seem at all noticable.
Frankly, even with the head phones its not very loud.
Funny bit of information -- if you want more juice out of your headphones, turn the phone off of silent mode, unplug the headphones and wait for sound to come out of the speakers, and than plug the headphone back in... youve now doubled your hearing loss.
Thanks for the tip. Can you restate the steps. Its not clear (and I could not reproduce it.) Maybe it would be more clear if you describe the original state of the phone. Example: Headphones plugged in and mute switched so speaker is muted.
Thanks
Okay here goes, My phone is usually on Vibrate.
Plug headphones in.
Start music.
Move slider to speaker.
Unplug headphones until you hear sound coming out of the speaker.
Plug headphones in.
I noticed this when listening to music on my headphones and i'd get a call, the volume would crank...
Give it a shot, it works for me!
I could have a bunk phone, but if it means anything I'm from Toronto, and i'm using a Bell Treo Pro.

[Update] Earpiece and voicecall quality

How do you find the Earpiece sound quality and voicecall performance compared to previous owned phones?
I think too many people where unhappy with the device because of the phone performance in general. I can't understand how such basic features where not treated as top priority specs.
It's " Who cares " typo sorry, not possible to edit the poll.
Thanks
EDIT: FLashed Radio 2.06 and voicecall quality is better but STILL CRACKLES
i find the sound quality is weird with this phone i.e.
rear speaker = loud but tinny, and seems that anymore than 70% volume and the software overpowers the actual speaker and causes distortion
headphones = ok sound quality very vocal friendly, quite nice for ambient vocal tracks, soft and fluff sound, i used shure se310 headphones so some of the best around
call earphone = very bad, even with the volume very low it still distorts when people talk, im not sure why this is and i thought it was a damaged speaker but its as if the sound is to harsh with the high feq.... so only call or accept calls from people with deep voices lol
It isn't necessarily the ear piece that's the problem, it's the VOLUME being pumped through it. The volume on my HD2 is ridiculously loud so I'm not surprised that my speaker is popping and distorting!
i went with the "it could be better" option
i always find myself switching to the speaker, then going back (repaeat cycle over and over with each call just trying to find an easy way to make out what people are saying.
a couple of mods would ultimately fix it, but im happy that the speaker is loud. Which kinda means its got the Umpgh
i use the headphines for music, i switched into an inear buds. it really makes a difference

Yes but it's TOO LOUD. I wouldn't mind if it went loud but I also want it to go quiet too, it's way too loud at the lowest volume setting. I can't use the speakerphone at all, it is destroying itself with distortion. I actually can't use the earpiece close to my ear either, due to criminally high volume. I use the earphone as a speakerphone - I kid you not. I don't know if it's just certain batches but my HD2 would be suitable for almost-deaf people.
Actually the keypad tones also are WAY TOO LOUD! I was in a meeting and it was like everyone was trying to find out where the was sound coming from... I had to turn it off.. a shame..
Not to forget also the pain the earpiece causes during phone calls. This thing is really sharp !!!
In terms of HTC phones, I've had the Kaiser and Raphael before the HD2, and I must say that the call quality on the HD2 is the best of the three! This wold be both through the speaker on the back (speaker phone) and through the earpiece.
I agree that the initial volume was way too loud, however there is a tweak somewhere on the board where you edit a registry entry for initial call volume, and that helped tremendously. So I'm actually quite pleased.
People who made the HD2 @ HTC Tech.. were a little bit deaf I think..
Bad speaker quality because of distortion and popping

Yea I think so, I am gonna try the registry tweak; hopefully it's gonna work.
voicecall is pretty bad because of the random noise similar to radio static. This nosie is particularly noticed when no one is speaking.

Same here ... someone spoke with HTC about this issue !?!?!?
I am not really bothered by the noise but by the poping and cracking sound the earpiece makes.
The registry tweak did not work for me as I expected
I will have to wait for a hotfix if any... I hope HTC will consider this issue...

have had the phone for only about a week but no issues with random noise. I do find that the loudspeaker distorts @ max volume, but just one notch below that and it's ok.
think the Touch HD has better earpiece / loudspeaker, but the HD2 can output higher volume on loudspeaker compared to the HD, so that's a plus.
maybe it's an issue with your phone operator?
For people who experience the background noise - Have you tried (if possible) both GSM and UMTS/HSPA (3G)?...

Yaah unfortunately that did not help
What tweaks worked for you guys to eliminate the distortion? when I lower the volume I keep hearing like a popping sound and cracks even with the headset.
Any idea? thanks.

I doubt that this is an operator related problem since my previous phone worked OK with this sim card.

Currently I'm only using GSM network but I will try making phone calls using UMTS. Don't think that will solve this problem though.
About tweaks I haven't tried any because all tweaks I saw were related to the distortion due to extremely high volume (which is not my case).

Same here, I need to remove the cracking noise, more like filtering the call quality, it's not a hardware fault im sure.

Earpiece volume

I just got it and noticed the earpiece volume is still low even with the volume turned all the way up.
Is there a setting I missed or maybe a registry fix?
Any help would be appreciated
HTC HD2
OS 5.2
MANILLA 2.5.2
ROM 2.13
RADIO 2.10
Don't mean to offend you. I had the same issue but was more of a user issue. I kept increasing the volume not paying attention that I was adjusting the ring volume and not the system volume.
if that doesnt work you may need to return it. My friends HD2 had low speaker volume and low earpiece volume. As much as we tried, we couldn't get it to go.
N1M1TZ - No offense taken, I only adjusted the volume during a call and at max it is still quiet.
I checked the settings/sounds, no adjustment for the earpiece just the ringer and the system sounds.
marduk79 - after doing a little digging I have found that this is a common problem with this particular batch of phones.
The first batch came out and the volume was set way to high that it was actually blowing out the earpiece.
I think I may have found a solution, if it works I will post it.
Thanks for the assist.
So what is the solution... My first one had sweet loud ear piece volume. But alas, the speaker blew. My replacement is alright, but I want it to be a tad bit higher... Lots of years of loud punk rock have made me slightly def I think...
Anyone know if there is a cab or registry tweak or something that will make the volume louder in the ear piece speaker?

How low? Like so low you couldn't hear it, or just low enough to be annoying? Basically my first HD2 was nice and loud. The new one is about 3 bars lower sounding turned all the way up... Which annoys me because I know the other one was louder and it's hard to hear people if I'm in an environment with a lot of background noise.
I feel like if I tried to take it in to get a replacement they would think I was nuts.
headphone and phone speaker too low
I too beleive the headphone volume is way too low, when listening to music or taking a call on the headphones it is barely loud enough too hear if there is any background noise such as traffic or conversations going on nearby. I have the volume about 75% when listening to talk radio stations, on my headset, no background noise present and it is at normal listening level. So if there is background noise, I need 100% for it to be loud enough to hear clearly. The phone speaker is not much better, when listening to calls on speakerphone the percentages are about the same for equvilent listening circumstances. I have tried "AudioPara3 TMO" and notice little or no difference in sound. Does anyone know of anything that will increase the maximum volume level for both speakerphone and headphones?
I'd like to know if there is any registry hack to increase the line out volume as well. My line out volume is very low, I have to put it to about 50 percent to match what would be the 20-30 percent level of my old HTC Touch (Touch 1 to HD2 - quite an upgrade, eh?? )

Did they lower the headphone volume on latest update?

I feel my headphones sound significantly lower on latest January update.
Did anyone else notice this? Did they do it to deal with the "hissing" issue some people had?

I'm on the latest build. The hissing is for me gone (or so quiet I don't here it anymore. At about volume 1 or 2 you maybe be able to here some. But like I said, to quiet to notice and only when you play something without sound ) I think it got quiter, but still damn loud on max. I love it.

Of course it's not "damn loud" anymore, it's significantly lower and not enough loud.
Does anyone know a way to being back the old audio output on headphones?

Maybe the build in equalizer could help you? You can easily access it through google play music settings..
Maybe its your phone? Or your headphones? When I'm on max I can literally use my headphones as speakers...
There is a new headphones audio menu with Oreo.
Configuration > Sound > headphones and audio effects.
There are some headphone presets, some are louder than others.

Maybe that to. Personally I didn't notice a big difference change those settings. It could also be your music player. SoundCloud for example can't be equalized through normal ways.
Hissing is still there, maybe a tiny bit lower. Max volume is still "damn loud", my max comfortable listening level (without ear bleeding) is not more than 50%. I often listen at volume 1 or 2 (out of 30).
Both earphone volume and loud speaker volume have been reduced for me.

Well, personally, I think that the speaker sucks, quiet or loud. I never use it. I really bought the phone for its "rare" headphone jack, which since the latest update is wonderful. Maybe headphone hisses a little bit, maybe they cancelled the Oreo update ( I believe) and maybe the speaker are horrible. But it's the best you can get with almost fully stock Android and a headphone jack.
Yes I wrote to much
Yes, I noticed this too...
I noticed this too as the volume that I used to play music at (about 60%) with my headphones was MUCH to soft after the update! Something definitely lowered the volume, though it SEEMS that it is more on headphones than the speaker. I have to go to max when on headphones to listen to music now. I say 'seems' because I don't use the speaker for much more than phone calls, and while it is quieter, it is not so quiet you cannot hear the conversation. It would be nice if there was a way to get the volume back, but I'm not going to hold my breath.

Xiaomi Mi In-Ear Headphones Pro HD that I got a deal on when I bought the A1. They are ok... not great, but ok for what I paid for them.
I've tried multiple headphones since the update, and the volume issue is true across the board with anything plugged into the headphone jack. I have NOT tried bluetooth headphones as I don't keep bluetooth enabled.
My wife's red A1, which is still on Nougat, is much louder than my A1 on Oreo, update 1. (still haven't gotten the latest one)
--KB
maybe they lowered to power of the DAC because everyone was moaning about a tiny hissing noise, the only way to stop it is to buy more powerful headphone or lower the DAC, now its quieter we cant have it both ways guys

I honestly can't imagine listening to any of my IEMs at max volume. I can't get comfortably over 50% while commuting (bus, train etc). In quiet environment my volume's somewhere between ~3% and 16%. I would accept further lowering of overall volume to remove the hissing noise in a blink of an eye (and hopefully I'll be able to do that with custom kernel)

I've never noticed the hissing noise people talk about so much, but then, my ears are old so it may be that. Before the Oreo update, a tick over half was plenty loud. After, I had to raise it, a lot. Some songs require max, while most are ok at around 85-90%. So yeah, there was a huge reduction in sound volume on my phone with the update. At least, I THINK it was the update. I installed a Sony app to record sound. I've only owned one Sony phone, an Experia 3Z. The sound on that phone was horrible. Even at max volume, you could not hear it ring if it was in your pocket, and music was always not loud enough on headphones. I may uninstall that app and see if the volume level returns just to be sure it wasn't the app and not the update, but doubt the app would affect the whole system.
I feel that too that they reduced the volume for the audio out put via 3.5 mm jack.
I got update today, and can't really tell if there is any difference in volume. I still use no more than 30-40% of volume (my head would explode with MAX), and there is still some hissing.
This applies to Oreo patch 1. Patch 2 arrived today but I have not installed it yet.:
I am not sure what I did (or what I did that made the difference) but I deleted the Sony app, then went into the settings on my music app and did some tweaking on the modes there, and the volume is now louder than it was. I can set the volume to about 55-60% now and it is loud enough. A few songs in my library still need higher settings, but I am assuming that is because they are pretty old, converted to .mp3 files from CD's (remember those?) way back in the late 1990s/early 2000s.
Bottom line: I am not sure that the update really hurt sound volume. It could have been a combo of app differences with the update. Still no hissing that I can hear.
Regards,
--KB
EDIT: I just did the new Oreo update (89MB) and the sound was different again. I went into my music app and changed the EQ to Flat and the sound was much better. I did not hear any hissing, even with classical music, but again, old ears may be the issue there.

Both speakers playing?

So my phone took a tumble very soon after I got it and I've noticed that when playing audio, I get sound coming from the earpiece as well as the main speaker. At low volumes it's basically a distorted rumble, but somewhat clearer when the volume is higher.
Also during phonecalls the earpiece is noticeably distorted unless the volume is set to 1.
At one point when adjusting the volume via the slider, I was blasted with a bass frequency, forcing me to restart to make it stop. Not sure if this was the cause or effect.
Is media playback meant to utilise both speakers?
Any tips on troubleshooting this issue? I get the feeling the hardware may have taken a beating but hoping there's a fix that doesn't involve me sending my phone away.
Tia.
Yes, both speakers are used, but these have different frequency range as far as I remember.
