My LG G7 ThinQ distorts with Quad DAC on at high volume... Without a DAC sound is clearer and louder, and it doesn't distort... Headphone jack makes noises when rotating it, plus while removing headphones from the jack a loud hiss happens... Is my DAC dying or is it a headphone jack issue? Please help...

if I had to guess I'd go with possible faulty headphone jack or your headphones, have you tried other sets of headphones and had the same issue? only thing I can recommend is check different headphones if it persists factory reset if it persists again take it to where you got it from and see what they can do about it.

The cause may be my resoldered headphones, but yeah, I tried other headphones and they also distort... Sound is a lot worse with DAC on... With normal mode sound is completely normal, which is why I suspect the DAC is dying... I just hope I can fix it for low price as paying $100 for something like that would be stupid... That is the only reason I bought this phone and now it distorts... Qualcomm DAC is not bad, but I prefer ESS DAC...

Got my g3 today and I loved it to I connected a headset....
When I connect headsett it's goes beep beep once and with my bose headset it makes interference sounds.
Anybody else have this issue?
I think i get it with earphones in the box at certain volume

I have the same issue. With my custom headphones I hear a lot of hum noice during music play but with other headphones it's ok so I think that problem is with impedance. 25 ohms for custom (1964Qi) and 15 ohms Sony MH1C. If anyone can test it or has idea how to solve it?

Today I tested 2 LG g3 and 1 LG G2. All off the phones do have this issue we have. But only with my bose. Testet nye pair of headphones and same problem so our phone is OK and I am buying a new headset possibly wireless
C'mon I don't think that problem is in my 500$ headphones. It looks like some incompatibility but needs to be investigated somehow. Some portable headamp or DAC can help as I need good headphones

The problem is in the LG phones not just ours but all LG phones. Maybe it is software related?
It's possibly hardware related and just poor isolation of the circuits used for audio on the phone. I hear the two beeps on earphones and headphones but little/no static.

It's cheaper. PC motherboards are only _just_ starting to get isolated audio as a standard feature and think how long they've been around. To isolate components from other parts you need more room as well, something phones don't have.
Try pulling it in and out a few times and then wrot wipe the connector. I've read some making this work. Seems to be an oil or something in there.
Update. This did the trick for me!
Hello,
Today I got new headphones but the sound quality is poor. I think it may be due to headphones having microphone - thus 4-pole connector. I know there are more types of these connectors, and I don't really need a microphone so I was wondering if something like this would help.

It is hard to tell... Maybe a little buzz, but I would say it's more like there is little-to-no mid range. The sound is just "boxy". It is perfectly clear on my old headphones which don't have a microphone.
Suggest me a good in-ear earphones under $100 with high impedance. I want to get rid of this horrible hissing noise.
This has nothing to do with impedance. I have in-ear headphones with 16 Ohm impedance (JBL T110) and there's noise as well. But I have on-ear headphones (Connect IT CI-235) and there's no noise at all. The issue is how much voltage can the headphones take. So I would recommend you to get some on-ear ones and if they're above 20 dollars they should do the job.

Someone said, we need to buy earphones with impedance of 32 Ohm or more. So when you buy better check impedance, it should be more than 32 Ohms.

Actually I do have 16ohm impedance earphone. Sony EX-15AP. Hissing is very much audible.
It's really weird, I have never heard this hissing.
I even just tried a pair of free ones I was given free on a sightseeing bus, quality is rubbish but still no hissing, I get a crackle if I twist the jack but that's it.
Problem is combination of low impedance and high sensitivity - which is pretty much case for majority of IEMs. Bigger headphones are often less sensitive so they do not tend to have the hissing issue. For 100usd, I would suggest buying any headphones you like + iEMatch impedance adapter (https://ifi-audio.com/portfolio-view/accessory-iematch/) - particularly if you need mic/buttons.
Edit: per iEmatch manual, mic/buttons on headphones will be disconnected by this adapter, so better verify with Ifi company before purchase.
Budget version would be ChiFi headphones (KZ, Senfer, ..) + cheap impedance adapter, but beware that this combination doesn't allow usage of cable with mic/buttons. I am quite happy with the budget solution..

Unfortunately I hear absolutely no difference in the hissing or overal volume of headphones. I'd say it's only a placebo "fix".. On the other hand, decreasing the headphones gain via custom kernel masks the hissing quite effectively - hissing is still the same, but as you have to turn up the volume, Signal To Noise ratio increases as well and you can't hear the noise over music. Quiet songs/passages are still bad though.

I got interested on this. I looked for some cheap ones but there is something i dont get, there are 30, 70 or 150 ohms so i wonder which one i have to pick. And some of those even say that they dont work on mobile phones so... I get even more confused.

I guess it only changes the gain or amplifiction. But my piston 3 almost gets no hiss with that fix. Super noisy without.

70 ohm should be fine, it will remove pretty much all the hissing and keeps overal volume high enough. Or there is an even cheaper and more versatile alternative - cable with analogue volume control (https://www.ebay.com/itm/131489435905). By turning the volume down, you effectively increase the impedance and hissing disappears. And you can fine tune it to each headphone. Though still no mic/button control.. I have similar one with button and mic on the cable and it makes wonders, but I purchased it years ago and can't find it anymore. Try to look for one in your favorite shops, you might have more luck.

No idea what it does, on my phone nothing audible. From the description it should do what custom kernel with sound control does - only mask hissing.
Just get a pair of Apple EarPods. They have an impedance of around 40-45 ohms and work great.
I have been trying a lot of custom ROMs recently on my Z2 Plus and I noticed the audio quality from the 3.5mm headphone jack is not particularly good on any of them. When listening to a piece of music or a podcast with quiet sections, a crackling noise is audible that makes it hard to hear any detail in the audio. The problem is most notable at low volume levels of just a few notches. I tried disabling any audio enhancements like the 'AudioFX' app that comes with Lineage-based ROMs, but this did not make much difference.
I listened to the same MP3 files on my ZTE Axon 7 and the audio is crystal-clear with no crackling present in the slightest. I'm using a pair of Audio Technica ATH-M50 monitor headphones.
I know the ZTE Axon 7 has a Hi-Fi audio DAC which might explain why it sounds so much clearer, but I didn't expect the difference to be this much... Is the bad audio quality just a limitation of the ZUK Z2's hardware, or is it something that the custom ROMs are not implementing correctly?
Which ROMs have the clearest audio quality from the headphone jack?

Thanks, I actually tried both of these tips before making this thread but I wasn't overwhelmed by the difference in audio quality... When playing music I still hear the crackling/static kind of noise during the quiet parts. I think it's probably a limitation of the hardware more than anything else.
Do you guys think using a 3.5mm to Type-C adapter with a built-in DAC would solve this problem? Then I could play music through the Type-C port instead of using the headphone jack.

You can always use a external dac via usb c port. Someone from zukfans.eu said it is working. But external dacs are expensive. Type c to 3.5mm jack adapters wont do anything if it does not have any dac inbuilt

Okay, thanks. The reason I mentioned the Type-C adapters is because I thought some of them were marketed as having an inbuilt DAC. But that could be wrong and the ZUK might not have compatibly to use it anyway.
Yeah, I don't like the thought of buying an external DAC since I don't intend on keeping this phone much longer anyway. I'm just having trouble choosing my next handset since the smartphone market is so stagnant at the moment. LG V30 would be good for audio quality but it uses PWM which hurts my eyes too much.
try paranoid rom nougat version, it was the only rom in which I felt the audio quality was better. ZUK 2 clearly have poor hardware, my old moto g3 sounds much better.
I wanted to start a thread discussing the performance of the headphone jack. I'm a bit disappointed considering Sony's audiophile history with their walkmans and LDAC codec.
Yes, I'm nit picking about a $13XX dollar phone but for this price, I was expecting a bit more that just average performance.
For comparison I do have a LG V40 with it's quad dac and it powers my audio technicas perfectly fine with High-Impedance mode.
On the MK ii, I don't get the full sound with out an external dac coming into play.
I'd like to ask other MK ii owners if having just a headphone jack is enough to power your earbuds/iems/headphones.
Going to do a bit more in detail research within a couple of days but I think Sony just wanted to slap a headphone jack just to say it has one.
Ps- I'm no audiophile but having a full sound for the headphones I have is a must.
Thank you! This thread is very interesting.
I have reduced hearing and I badly need a smartphone with high-output. My LG V30 with it's QUAD-DAC has no problem giving me enough volume even on my favourite pair Hifiman HE-4xx.
I was hoping that Sony 1 mk2 was an alternative, but maybe not................ ?

You may want to make the distinction between headphone jacks that can and cannot drive high impedance headphones as a headphone jack that can't can still be good as in clear, little to no distortion with good response and sound reproduction.
In this case its more like LG's has gone out of their way to include a dac that can power high impedance headphones (which is rare in the first place, in addition to the jack being rare) so if high impedance headphones usage is a top priority, then sticking to LG would be recommended.
I have a Meizu Pro usb dac which has a good reputation. The volume of the Meizu is a bit higher, but the audio quality of the Sony is equal. You just have to increase the volume 2 or 3 notches. The Sony uses the Qualcom dac and excellent Cirrus amplifier chips. I use my Beoplay H6 over the ear headphones for listening. The volume being a bit lower is no problem for me, I still can get serious hearing damage if I want to.
The audio is detailed, excellent channel separation, noise is undetectable.

Yeah LG has done the headphone jack justice, but I was expecting a bit more out of the mark 2 for it's price point.
Like hi-res audio. I get it's mainly a photography oriented product. I mean I guess I got used to only using half of the volume steps provided by the LG phones.
I just had high expectations out of Sony in the audio department. Great camera. As for the dac mentioned above, i have a couple so I'm not too worried about getting any more of them. I have a couple of headphone I can try out besides my audio technicas.
The audio capability of the phone is lacking
Bluetooth volume is pretty poor even though it's decent quality
The 3.5mm Jack absolutely doesn't have that much power to drive much more than basic iem 8 to 16 ohm level. Can't push my 150ohm cans at all
Definitely louder than the previous phones. I'm just happy that the jack is back. I did notice a difference with bluetooth vs wired on WH1000XM4. Volume was definitely louder on bluetooth, but can really notice the difference in quality despite LDAC. But that's just me.

But it does have Hi-Res audio. Volume is a bit lower, but is also the curve of the volume control. With the LG the volume control is linear, with the Sony starts to increase real slow, until over half of the volume.

Yeah volume has to be over half way to start making decent sound. Regular buds are fine though. I have some kz iems and it's fine with those. Just higher impedance isn't for this phone.
My Beoplay H6 headphones have an impedance of 30 Ohms. They work great with the Sony. I can't compare, these are the only wired headphones I have.

Try to dm peter. I didn't have a chance to save this.
Sony Xperia 1 II most probably uses a Qualcomm audio codec. Can be their flagship Aqstic WCD9341, a dedicated audio chip. Only a proper tear-down will reveal the details. As I found out this audio chip contains a very good DAC section and can produce nearly 1 Vrms at headphone out when implemented in high performance mode.
