Has anyone figured out if you can use the phone as an "external DAC", use the ESS DAC but in a "line-out" mode for connection to a stereo via analog cable to their stereo line inputs? I tried using it normally, and the DAC showed as enabled, but the quality was not as impressive as I had hoped (in comparison to my Marantz UD5007 when playing a standard red book CD via it's analog output to the same input on my stereo).
thanks!

What kind of cable did you plug in? LG set it up to limit the DAC based on the cable plugged in, I'm assuming they did this as most users probably use earbuds and the DAC at full power would probably damage most earbuds. And I've found in my car, plugging the aux cable in when its not plugged into anything enables the DAC at full power. I didn't discover this, some on headfi did.
I'm using a 3.5mm to stereo RCA cable into the line inputs on my stereo. The phone shows the HiFi DAC as being enabled but it is not in Hi Gain mode, and I get the HiFi volume adjustment levels when I change the volume. So basically the same as when I use it with my IER's, but not Hi Gain mode like when I plug in my Sennheiser HD580's. Which is fine, but I'm wondering if I can bypass the amp while still using the better DAC.
thanks!

I have an iBolt car dock, which has a dock connector on it that then splits out to a 3.5mm audio out and a car charger connector. These work, but I found the output level was quite low when feeding the aux input on my car, even with all settings on the phone turned up (master and media volumes). While searching online, I found an impedance matching device that is designed to match the output impedance of a phone's headphone out to the aux in on the car. It works quite well, but I found it ONLY works with the headphone output jack of the phone, NOT the output jack accessed through the docking port. When using the dock audio output, the audio through the transformer is very thin an tinny, making me believe the output impedance of the dock audio out is different from the headset audio out on this phone.
I know it's an odd question, but any thoughts/experience with such things out here? Without this transformer involved, the quality and volume of the audio on both of these outputs seems identical. Only when using the impedance matcher is there a drastic difference.
Thanks,
Chris
If you are rooted and running a kernel that supports it, you could try a sound app like voodoo or boeffla to raise the gain and see if it raises the output via the usb port.
PBJ kernel supports boeffla
Saber supports Voodoo
If it's loud enough but thin sounding you could try bass boost in voodoo.

Is it possible to get the Hi-Fi DAC working with a Bluetooth headset?
I think this would do the trick for you http://forum.xda-developers.com/lg-v10/themes-apps/dac-fix-hi-fi-dac-everywhere-t3274457
But really ??? on Bluetooth??? I think you would just be using up more batter for no better sound due to what Bluetooth does.
It's impossible to have the DAC affect bluetooth sound. The data is sent to the bluetooth device.... You would need to plug in a aux cable and plug it in to a bluetooth adapter and well just don't do because you'll need to carry a powersource for that and the adapter and just no lol. DAC - digital to analog converter, so yeah it's still digital when sent through the phones bluetooth.
For the best bluetooth audio get devices that support aptx and if you can find devices that are either bluetooth 4.1 or 4.0.

Even if you plug an Bluetooth adapter in the aux output you will not use the v10 dac for your headphones. It would be: phone DAC - Bluetooth ADC - Headphone DAC.
So probably it sound worse after the extra converting and it defenetly different as if you plug it directly in the phone (dac color the sound)

Ya, your definitely right. Converting to digital and analog back and forth 3 times is like taking a photo and putting it on a copy machine and then making a copy of the copy and another copy of the copy. It's not going to look good at all.
Yes the sound would get worse. I wasn't thinking when I posted this I am a audio engineer so I know a little something about audio lol! Having a long week and I wasn't thinking when I posted this just moved into a new house. I'm used to using viper4android on my Nexus 6 so when I couldn't do that on this phone I got frustrated. But anyhow I'll have to wait for root thanks anyways members of xda! Appreciate the responses!
Hey guys,
I would like to know, how I get rid of the "normal audio device" mode. I had connect Teufel Massive reloaded and the included headphones but it shows in the HIFI settings only "normal...".
Best,
Kalle
I believe those headphones have a removable cable, correct? If so, try unplugging the cable from the headphones, plugging just the cable into the phone, and only then plugging the cable into the headphones. This should trick the phone into "Aux" mode, which functions in the same way as high impedance mode.
For low impedance headphones without removable cable (or if the above doesn't work with your cable), buying a headphone jack extender like this works:
http://smile.amazon.com/gp/product/B00ZK43S4Q?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Same procedure, plug in the jack extender without your headphones connected, then attach your headphones. Should display aux mode indication in the settings
Normally the amp only kicks on for full power with headphones that have an impedance of 50+ ohms, but the above trick should work. I've also read about another workaround involving making a phone call (like to your voicemail) then plugging in your headphones, but I could never get it to work, so the above method seems more reliable
unbeliveable - this works. Danks!
It's easy to force high impedance mode.
I've got a set of headphones with a detachable 1/8" jack at both ends, but you can use a splitter and an extra 1/8" double male plug cable as well.
I use the 1/8" cable and connect my v20 to another cell phone or tablet headphone jack. It immediately goes into high impedance. I unplug only the end going into the other phone and plug that end into my headphones. As long as the cable stays plugged into the v20 it stays in high impedance mode
If your headphones don't have a detachable cable, it'll still work with a splitter and a cable that has male 1/8" plugs at both ends.
Using the splitter, plug your splitter into the v20. Use the double 1/8" jack cable to connect the splitter to a phone or tablet. Once it's in high impedance mode, unplug the cable from both ends and connect your headphones to the splitter. Don't remove the splitter plug from the v20. As long as the splitter stays plugged, you'll be in high impedance mode and get more power into your headphones
Ok...what is the use of high impedance?

its just wasted a time, and change nothing on everything you hear. look, high impedance automatically triggered only if you put headphone with 50 ohm above. you know why? because regular phone or music player only could deliver impedance with range 15-30ohm. while lg v20 like any other DAP with external amplifier could support from 50-600 ohm. even with 250 ohm headphone if you put on regular phone it would only run on 30 ohm max. and same goes to your phone, even with your v20 or any DAP player which support 50ohm impedance above, if you connect to low impedance headphone it would only run on your max headphone impendance. its not something you could force to work.

Bro I agree with you. I have used 60ohms headphones and 45ohms headphones with my Lg V20. With 50hms and above, we can see "high impedance headphones connected" in settings.but nothing improved in sound quality. So doing force high impedance is unnecessary.

check your audio files first, make sure you have lossless audio like flac or dsd. for flac i recomended using song with 24bit/96khz. if you playing with stock lg music player you'll see there is "hifi" icon on the selected song. join audiophile comunity for more reference. and for headphones , well.. there are many type, some headphone have flat bass, more vocal, etc. choose one which suits you and the music you played. from what i got while browsing on auido/video community, there are 3 main requirements for best audio experience:
1. good drivers aka player like DAP/AMP or our beloved LGv20 which support impedance above 50 ohm
2. lossless audio files like flac, dsd/dsf which support hifi system
3. good headphone with high impedance that has many feature depends on your need. some people love high bass, while other prefer clear vocals, etc
lg v20 is a good drivers, its not the best but its good if you dont wanna spend another 150-250$ on music player with dedicated amplifiers.
High Impedance Workaround
I was thinking the same thing on an easy workaround, so I bought a $3 splitter, plugged in my AKG headphones which pulls up high impedance, then plugged the B&O earbuds. (that came with my V20)Then unplugged the AKG's and it remained in high impedance mode. Doing that, if you turn the volume up higher than 75%, you'll probably pop an ear drum. It gets waaay loud and clean!

Why not just use my mod and forget about extra cables?
NVM.. Just read no root. Sorry folks.

I never said it improved quality. I understand how DACs and amps work.
The reason for high impedance mode.... If you have headphones with less than the 50ohm threshold, high impedance mode increases power output from the amp. The result.... On low impedance headphones you get more power which means higher volume output.
I have a set of V-moda Crossfade LP cans that are less than 50ohm. On the regular power level, max volume of 75 still lacks a couple decibels for my preference. When I trip high impedance mode I am able to reach a higher volume level and I usually don't need to go higher than 60.

Exactly... Higher volume output. I didn't say it improved quality, as others are arguing.

Look at my last post.....
Triggering high impedance mode and then connecting low impedance headphones will give you more amp power which equals higher volumes. Does nothing about increasing quality just higher volume threshold. But only if you trigger high impedance and THEN connect LOW impedance headphones
This mod worked with a splitter in my v20. Thanks @Sid 6.7. wow listening to low impedance headphones at high power is a fun. Great workaround.
Hi
I recently acquired some old but great quality USB desktop speakers. So no aux cable, just a standard USB connection for the audio.
I had an OTG cable lying around and surprisingly they work when plugged into my phone. However the speakers themselves do not have any volume controls and so max volume on my phone is fairly quiet on the speakers.
I've been doing some research and I think I have some hope in editing the mixer_paths.xml file in the system files. People use it to increase the internal speaker and headphone jack volume. However I'm unsure what to edit or if it's even possible to increase USB audio output volume.
Any help or other ideas would be massively appreciated!

It speakers have their own DAC (which I suppose they have, as audio over USB is mostly digital), you might have luck with this method - https://forum.xda-developers.com/mi-a3/how-to/guide-apple-usb-c-to-3-5mm-dac-dongle-t4069437
I'm presuming the speakers are not externally powered and get there power also from the USB connection?
If so then there is probably nothing you can do as the phone cannot supply that much power to output louder music without the speakers being plugged to an external ac source
