Hi all! I have been reading alot of post about Streak's low quality sound output, and I'am experiencing it too, when I plug in my head phones there is no hissing sound, but when I click play or receive a call hissing sound starts and does not end till audio output end.
There is alot of post from people that have the same issue, I will Quote them below. I'm posting this because everyone that has posted this issue has been "overrun" with other people posts that they do not have that background noise.
I just want to expand on this problem, could it be Android version, or perhaps different hardware? Any suggestion is welcome.

Hi,
Personally I find that whatever I use as earphones, I have a hard time accepting the noise level on the streak. When playing music at a medium volume, the noise is really very very present.
I suppose there is no work around is there? Doesn't this bother you for serious listening?

The sound quality is absolutely abhorrent in comparison to the Galaxy SII or any other smartphone I've ever used, including the HD2, Vibrant, several Nokia devices, etc.
There is a constant and definitely audible signal noise in the Streak that really bugged me. As a recording engineer, I can definitely hear the difference between the audio systems on the two devices. When the playback system kicks in, you can literally hear the hiss in the background. When the playback stops, the hiss vanishes. Upon further investigation, it seems that this is a known issue that found its way into several reviews. If I hadn't heard it for myself, I'd have not believed how terrible it actually sounded, and frankly, it's SO bad that I find it inexcusable on such a high-end device.
I sold my iPod and bought a larger MicroSD to use my phone as my main portable media device, and the Streak really let me down.

If it's boosted, wouldn't that cause more noise since noise will also be boosted?
I'm having the same problem. Hissing noise in the background. I also got mine couple days ago. I bought it when it was $200 unlocked from dell.
I'm on stock 347. I should have tested the earphone when I had 351.
It makes the hissing noise in music, internet radio, wherever sound is being played. It has a constant level of hiss noise even if I raise the music volume or reduce it to minimum.

I believe it's the hardware. Doesn't matter what OS level you're running (I've experienced it on 2.1, 2.2, 2.3)
I've actually found it to be more tolerable on the Dell oem headphones when compared to my nice headphones (etymotic research er6i)

I hope its OS because some don't have this issue, maybe MIUI 2.3.2 Rom wont have this problem (when they fix the problem with headphones not being recognized).
And yes, on Dell oem headphones it is less noticable but compared to 50-100$ better headphones, Dell's are low quality, although they are one of the best in box headphones that comes with device.
I have some basic knowledge in Java and C. Could anyone point in the right direction so I can try to edit/tweak some setting of audio output. Any info would be appreciated.
It's also noticible on the S7 and venue. At least on the S7 you can only really notice it in a room that's completely silent, but at least for that i'm talking about the external speakers.
All I can say is that it's pretty much not noticible for me as long as it's not silence/very low volume music. At least for me it's very easy to drown out the hiss by raising the volume as it does not/minimally scales with the volume.
Keep in mind that the speakers/headset jack simply do not recieve power when not in use, the hiss on them could be part of the inherent design of it. It might be noise after the DAC as it doesnt scale anywhere near 1:1 with the audio. But I'm just blindly guessing

Did they came up with any fix for S7 and Venue?
In DSC rom update there is a line that says:
I'm using MIUI so can someone confirm if this changes anything?

The V has pretty much no perceptable hiss, and I believe the V and S5 share the same audio drivers (dont quote me on this), it might merely be a hardware issue on the S5.
I cant really say much about the S7's headset out, as it's rather unwieldly to use that way.
Also I'm very sure that it ISNT dependant on volume, like previously mentioned unless your current headset is loud to begin with, just turn up the volume and it drowns out nicely.
But yes it will be noticable on the quiet parts of music or during track changes.
tl;dr: turn up volume, V's got a cleaner output
Equipment tested on:
S5: CM7.2
S7: SD7-r9 (514-xx)
V: SD4-250 (408)
headset: iphone in ear headphones
I think its just the poor SNR ratio of the streak, its only -79db or something, its very poor.

Makes me sad
Hey Guys.
I'm creating this thread since I did not find any other old thread about this issue.
When a song or any audio output is done through the Redmi Note 3's Speaker or when it is connected to a Amplifier like a car stereo then there's an Awkward ssssss or Hissing sound.
I've used Two Different models of the Redmi Note 3 thanks to Amazon and both of them have this.
It has a very very low possibility of hardware error.
When a song is played at 1/7 of the total volume, put your ear near the device speaker and listen carefully. You might notice a weird hissing sound. It goes away when there is deep and strong bass but is there lots of times.
Using an amplifier it is most noticeable at lower volumes.
I hope you people understand.
Respond ASAP!

I too faced that situation... But in my case..
The 3.5 mm jack is broken..
I mean.. There's no problem with the phone.. But in sound system I use...
Have you checked this problem with other speakers ...??

Hey,
I actually have noticed this when I played music in my Car and also from the phone's Speaker itself!
Both when the volume is Very Low....
I know it's not a problem with my piece because I've checked with many RN3 Users and same issue is being detected there too.
My RN3 is new and in superb Condition and so are the other Appliances like the Car Stereo I used.
Even then this Hiss sound is there.
I wonder of its a problem with the Chipset altogether since there isn't a sound/music chip in it...
I hope it's a software issue and gets resolved fast...
When recording sound from the speaker output yes the sound is levied towards the high end, this is probably what causes the hissing sound in your amplifier since it can't properly amplify that freq or something along those lines, I'm not too sure since I'm no sound engineer but that's just my 50 cent.
Edit
Dumb me, your amplifier is probably a 3.5mm headphone Jack right? If so then there shouldn't be this issue and my above statement wouldn't apply ;-;
I noticed this when using Viper Audio. There was a small but noticeable hissing in the left earphone. It went away when I turned off playback gain control.
Maybe check if any equalisers or headphone effects are on and turn them off?

I had checked everything possible. I even did now.
No part of the settings, equalizer, audio effects could fix it....
And where's the option you're talking about for playback gain control? I'm still unrooted with a locked bootloader on MIUI V7.2.3.0LHOMIDA
The sound is there in both speakers in my case. I'm not using anything other than the stock music application and some great songs on an amplifier I.e. Cars stereo
Anybody has got the solution? I am also facing same issue ??

If your Stereo supports USB and Aux in, you can also go for the adapter since it only needs those two.

I had a similar problem. Whenever I connected my headphones to my Redmi Note 3, there would be a weird hissing noise at low volumes especially. At higher volumes, it would reduce. I found a fix to this on Reddit, but you need to be rooted.
https://m.reddit.com/r/Xiaomi/comme..._3_pro/?utm_source=mweb_redirect&compact=true
Looks like a legacy. We are well into 2017 and the issue still exists. I bought my RN3 a couple of weeks ago and noticed the hissing on the third day of use. I just have been ignoring it. After all, it's a Chinese phone. I bought it and I have to live with it.
Good afternoon! The solution for problems with Redmi Note 3 and AUX is the following (solves the problem of correct detection and noise during playback): it is necessary to solder or otherwise connect resistors with a rating of 10 ohms between the common "0" wire and the left and right channel wires (I did 17 Ohm , did 10 ohms - both options work).
After you make this cable, the sequence of actions is as follows: the cable is first inserted into the smartphone, wait for the icon to appear with the headphones, and then insert into the AUX-input of the radio or audio system.
Ok I searched for Solution on google, it seems no body else is facing this issue. So here is my problem I migrated on to v30 from v20 and I noticed that whenever i play a song with quad dac on there is a very audible static noise in the background, like if the mic on or a better example would it feels like the song is being played on a radio.. where along with song there is a hint of crackle and white noise. My V20 never had this problem.
Is anyone else facing the issue, BTW I am on Philippine oreo KDZ, and will LG cover the warranty or should i wait and flash Indian Oreo to claim warranty??
did you try different audio sources, headphones, also try some speakers

Look: you ever used the "high performance" mode of the WCD9xxx in-built DAC of any previous Android phone ?
This raises up the output but also comes with the cost of higher "white noise" / static, etc. - this in turn is able to drive headphones with a high impedance Ω
The same applies to the dedicated "quad dac" - it has high output by default and thus is to be experienced best with "high quality" (well, most high quality headphones have higher impedance than the very cheap headphones).
There's a noticable difference for me when switching between e.g. the EP630, Xiaomi Pistons and the provided B & O Headphones that came along with the V30.
So there is NO issue and there is not really a solution but to use it in the way that it was meant to be used

If a DAC has distortion and audible static interference then its not doing its job. In simple layman terms, Switching on DAC should improve sound stage and frequency response and it is noticeable on any even basic headphones. Like I mentioned in my post I have Lg V20 too, and the DAC on that phone doesn't have any of the issue which i mentioned about my V30, to which you say is not an issue. Also Headphone (Mi Piston) is not an issue.. coz the same headphones works perfectly on V20..

well, it could be due to how the driver & kernel is compiled (so it would be an out-of-the-box issue) - I've experienced this kind of increase in static noise on the Z5 once going from fstack-protector-regular to fstack-protector-strong (more functions protected or "tainted" in that case)
https://outflux.net/blog/archives/2014/01/27/fstack-protector-strong/
https://lwn.net/Articles/584225/
https://en.wikipedia.org/wiki/Buffer_overflow_protection
Since the stock kernel is built that way by default the audio output quality could be somewhat worse compared to V20 (if there the kernel was compiled with fstack-protector-regular).
I can clearly hear how there's some distortion and audible static noise when the screen is off, quad dac enabled and changing volume (up or down) - the amp first is gone, the output is much more silent and there sound is less clear - more static can be heard
I've attributed this to the quality of the audio tracks I'm listening to - since with fully digitally created tracks this didn't seem to occur that much.
Also there's one particular issue I had forgotten:
Once connecting the Xiaomi Hybrid Pro and having Quad DAC disabled (so the stock WCD94xx used) either on left or right channel (every several seconds) there is solely (no other output) very loud static noise while playing music [similar to the static on old-ass TVs where only static is being shown and similar sound played],
when enabling quad dac/ES9028PRO it's gone. No matter what audio track is being played this was happening - I wasn't sure whether this was a software or hardware issue and since this was only happening with one particular type of headphones/IEMs I keep the phone so far.
Since you mention that the static noise appears along music output I doubt it's a similar issue you're observing.

Yes I did.. And by v20 i mean i tried all Flac, same mp3 on both the devices, wired speakers, headphones, so it doesnt seem the problem is with any of the external devices, , tried different music player, same problem it has to be issue with V30's dac or the headphone jack its just when i start playing a song with Hifi option on, the static and light crackles starts and when the song finishes playing or I pause the song the noise stops after like 15 seconds or if i turn off the dac the noise stops immediately. But toggling hifi option on and off without any music playing the issue doesnt exist, its just when a song starts and DAC kicks the issue appears, so i doubt its even headphone jack

I wish i could have tested on indian nougat when i had it, to see if it is oreo related issue, now i have to wait for Indian Oreo to see if that rom has the solution. I think Ill probably send it to LG to fix it while its under warranty
Stock Nougat, just going to start the bootloader unlock process, but sonically it's been flawless, orgasmic actually, with Sennheiser 6xx's, Etymotic HF2's and ER4's as well as BT to a UE Boom. Only the occasional crackle because my HF2's cabling is getting old, so sadly I'd think you have a bad unit.
Even I am experiencing the exact same , I'm on Indian Oreo kdz. When I turn on high impedance mode with sennhieser hd 598 and then connect it to my ath e 40 , I get a continuous hiss throughout the song.. sometimes it's irritating really.. I want to ask if someone who has rooted and using whiskyomega mod having same issues ?
By the way I don't get it on hd 598 , it probably dampens it..

The HD598 is 50 ohms (more resistance) while the E40 is merely 12 ohms, with a dynamic driver, I am guessing fairly sensitive. I wouldn't use HIM with earphones like that in the first place. That said, V30 is known for having a very low noise floor, so I wouldn't expect hiss, even with HIM and sensitive earphones.
Which music player do you use and what is your music source? Unfortunately V30 will upsample 44.1Khz sources (i.e. all CDs and most streaming sources) to 48KHz before sending it to the DAC. This should not be audible in most cases, but a few people are able to hear it when using very sensitive IEMs (typically balanced armature drivers). It is described in the opening post of the thread linked below:
https://www.head-fi.org/threads/music-apps-tips-and-tricks-for-the-lg-v30.868978/
The way around it is to use a music player that bypasses the standard Android audio path, such as UAPP or Neutron, both of which use their own audio driver that sends music directly to the ESS DAC.
Another possible explanation is if some EQ or other processing in your music player is messing with the data before it reaches the DAC. If you try playing with UAPP using Bit-perfect mode, that's a great way to determine if it is a hardware problem (which is possible) or something in the digital audio path.

This sounds similar to what I experienced with my V30S using Beyerdynamic iDX200 headphones with the extension cable design*.
At first I thought I had received a defective V30S. Then I found the problem was limited to those particular headphones with their included extension cable. With the extension cable removed, and with any other headphones, the V30S audio quality problem disappeared. And the iDX200 sound fine on my other phone, as long as the extension cable connection is clean (it is prone to signal degradation by contamination).
My guess is that the V30 system that measures load impedance on the 3.5mm jack has some kind of anomaly related to imdedance/VSWR imposed by the connection of the iDX200 extension cable, even if that connection is clean.
Try different headphones.
(* The iDX200 cable is too short by itself, it has to be used with a short extension, either the included one or another.)

Go to hifi settings in balance section, reduce the volume from left and right to as low as possible, I've kept it zero and just raise the volume to your liking..
In my case the hiss has reduced drastically to the point I can ignore it ! Hope this works for you!

Great! I'm glad you like it.
And interesting that it solved the noise problem too. That most likely means it was the artifacts caused by upsampling 44.1KHz to 48KHz (performed by Android's standard audio path) that you were able to hear.
UAPP is my favorite too, both for its features, its ability to play redbook (44.1KHz/16bit) without upsampling, and for its user interface. Neutron can do that too, but I could never understand its user interface.
In UAPP, under HiRes Driver flags, make sure to select the MQA flag if you play MQA files or streams. This will ensure that the ESS Sabre DAC is fully utilitized for MQA playback.
Correction- high impedance mode when switched on, even this app makes the noise , I had tried without the high impedance mode..?
but still ,otherwise quality seems better than the stock ! ?

Something is wrong, that just doesn't make sense. If anything, there should be less noise (if the theory of HIM activating more DAC units is true). And in any case is the V30 known for having very little noise, in any of its modes.
How do you trigger HIM? If you plug your headphones/earphones in directly (no adapters of extension cables) is volume loud enough?
If you play music through an impedance adapter, then I suggest you don't. Unplug the adapter once you've achieved HIM, then plug your headphones/earphones into the extension cable (or TRS adapter).
And if you don't need HIM to drive your headphones/earphones loud enough, I suggest you don't need it for maximum sound quality. The V30 was designed to adapt its output mode to the connected headphones/earphones. While it fails to do that correctly with planar magnetic ones, it does it correctly on most others.
Still, unless you are playing through an impedance adapter (which will change the frequency response of your headphones/earphones) or through a poor quality extension cable or TRS adapter, I cannot see a good reason why HIM should have more noise.
Ath e40- when i connect without adapter, loud enough, okayish sound.. Just like any other device..
There was this one time the high impedance mode got activated by mistake, mustve been a glitch! but my god the sound !! - more punch, more soundstage , even minute details audible , more dynamic!! way more louder! Then i searched around and found a way to trigger it everytime by using ath cable extention and sennhieser hd 598 , then unplug senn without unplugging the cable And then connecting e40.
This time i could hear the hiss.. Whenever i plug the earphones only, theres no hiss, and quality is okay.. even though the hifi option is on. i guess it just uses the snapdragon dac or whatever.
to summarize-
if i connect the cable first and then e 40 - sound is louder and okay.
only e 40- sound is okay.
senn and then e40 (to enter high impedance mode,probably uses the quad dac for real this time)- sound is amazing!!!! but with hiss...
I've only used the stock music player uptil now.
now i use uapp- it still gives me the hiss when high impedance is on. otherwise the sound is a bit better than stock music player.
Hey, I'm not sure if anyone else is having this issue but when the dac isn't on, it's static during the music and when I'm in a call, there is static in calls on the left side. Does any one have a fix for this? I've had these headphones in my V20 and this is my first day with my V30+

Hi,
haha - and here I am and thought this phone was having hardware issues or something (does it ?) - perhaps it's just the headphones and they have an inherent flaw ?.
At least I'm getting the same weird behavior that at some points it plays fine but at others there's LOTs of (electric sounding) static on the left side.
It's actually never fully continuous for longer periods - it's more of a stuttery (multi-second) behavior for several seconds that this noise appears.
Also at first it was only via quad dac enabled - on AOSP Pie (internal LineageOS 16.0 build) it's existing no matter whether I play via Android Audio or Hi-Res Audio (USB Audio Player Pro).
And this exists on very low volume levels - there seems to be a connection that when the volume levels are raised (above 25/30% or so - I'm usually listening rather low but with this phone and hi-res - why not go higher ?)
it's way more salient and there also may be distortion involved:
An especially remarkable track in this regard is Thomas Bergersen's [from Two Steps From Hell] "Lost in Las Vegas" (around 08:30 or so towards the end, 10:14 long) towards the end - a rather electric part of the track and
when you raise the volume the output becomes rather distorted which might be connected to that "issue" and the left channel is also hissing/giving off static way more.
Perhaps audiophile folks and audio hardware experts have a better idea what this is hinting at ?
So:
not sure if it's an issue itself with the Xiaomi Hybrid Pro HD that they can't take that extra AMP (they are supposed to be low impedance and thus not require high output)
but somehow this behavior only occurs on the LG V30 - so perhaps there some kind of hardware issue ?
It seemed to have gotten better however from my impression with all those updates to the subsystems in the kernel - so it's perhaps just bad hardware design and the headphones are rather sensible
with their balanced armatures ?
Anyone else with balanced armature (BA) headphones observing a similar effect ?
I haven't had any trouble with my (dynamic driver) headphones. I wonder, have you messed around with forcing high impedance mode?

You mean high impedance adapters and such ?
Nope, only directly connecting the headphones.
And whereas before it only happened with the quad dac activated (which might provide more juice),
it now also seems to appear with the internal DAC used only (toggled via USB Audio Player Pro).
There might be a difference on how the internal and quad DAC interact or are active on recent Pie AOSP ROMs however ...
It still doesn't explain that weird behavior from the headphones themselves
Thx
I have tried it stock with no mods and it has static. Slide down the drop down and turn on the Dac and it goes away but only for music and system sounds. With calls it definitely makes noise all the time. I tried with a AOSP rom and it makes noise system wide because of the Dac. I did try my Phillips headphones and those work fine without the Dac on but I think it's a specific issue with these ear buds because I also have a 2nd pair and they also make the same noise.

yeah, the Xiaomi Hybrid Pro HD are the only headphones so far that show this kind of "behavior" with the LG V30,
not sure what is up with that.

very well could be, I wonder though where the reason for that might lie and if a fix of some sorts is possible - quite like those headphones and would like to use them on the go

Trying to figure that out myself. I love these headphones now I have to find replacements
