USB DAC - Lenovo P2 Guides, News, & Discussion

Is there anyone who have tried fiio dac with your Lenovo P2? I have a fiio k1 dac and it doesnt work with my phone but works well with my old samsung j7(2015).Does changing my stock rom help me with this problem?

For me i have managed to get it to work a few times. Reconnecting multiple times and it would work 1 out of every 15-20 times. Very unreliable and I'm afraid i'm damaging the phone in the process.
I just use allcast to stream music to my laptop which then outputs to the dac as a workaround.

Thanks a lot for your reply.I thought this problem was only with my P2. I have tried as you said.Reconnected multiple times and usb audio player pro plays the music at a very loud volume enough to damage the headphone and then all of a sudden the app crashes.Same case with Neutron music player.Poweramp detects the dac and plays song but no sound is heard.I think any custom rom can help me with this problem

P2A42 (hardware p2c72) here same problem only charging Fiio X3 first generation, used to work on OnePlus one and Moto G third generation

I'm using Lenovo P2 unrooted with Stock.
My Fiio E07K didn't work but I could try some others and the Audioquest Dragonfly as well as the Cyrrus Soundkey work like a charm. The Oppo PM-1 didn't work either.
I'm very happy with my new Soundkey...

I'm also using unrooted Lenovo P2 with Stock (P2a42_S224_170725_ROW) .
I confirm that my Fiio Q1 works like a charm...
i havent faced any problem till now regarding the connection...

Stock ROM, FiiO E18 KUNLUN fully works.

[Q] Bose QC15 noise canceling headphones not working with Moto G

Hi all, I got a Moto G 8gb from Phones4U, and my Bose QC15 noise canceling headphones made a nasty clicking noise every time they were plugged in. The clicking would happen no matter if something was playing or not. Nothing would play out of either channel, and the software would randomly pause whenever they were plugged in, as if they were being unplugged. Various cheap earbuds worked, but not my QC15s. I factory reset it three times, and obviously tried the headphones on about a half dozen devices, including a Galaxy IV, iPhone 5C, Nexus 5, my laptop, my desktop, and an old iPod Classic -- all worked perfectly.
I took it to Phones4U and exchanged it for another model, which had the exact same problem. We tried a 16gb version and it had the exact same problem too. Then we tried it with various other phones and my QC15s worked, so they told me that my headphones must obviously not be compatible with the Moto G line. Then they said I wasn't even eligible for a refund because it was about compatibility, not a defect. I raised hell and finally got them to refund it, but now I don't know what to do. Anybody else have noise canceling headphones, especially the QC15s, that they have successfully or unsuccessfully used?

You were probably a bit hasty returning the phone just for this, but you're right there's something screwy about the Moto G's handling of wired earphones that are more complex than basic stereo. I can't get any 3-button remote headset to work with it properly, for example. No doubt Motorola will deal with this in future updates ... unless they only want us to buy the Sol Republic Jax earphones, which would not be good ...
I'm also surprised you got a refund, as Motorola doesnt claim compatability with your headset. Also surprised that Phones4U now have 16GB in stock

Just for the record I have a 16gb Colors edition from Brazil and I use a Sennheiser bluetooth headphone with my Moto G (PX 210 BT) and it works beautifully!
I can use all its buttons with no problem: play/pause, volume up and down and skip track forward/backward.
One interesting thing I noticed was: the headphone did not perform very well with Google Play Music. Both sound quality (it would constantly click during playback) and the buttons (play/pause button would only work with screen on) were not up to standard.
However when I installed my player of preference, PlayerPro, and messed a little bit in the settings of the app with audio priority and with the keyguard settings both audio quality and buttons were working great!

Yes, bluetooth is another matter of course. But I guess he has a reason to be sore when those wired Bose QC15 headphones cost twice as much as the phone itself
Workaround to make them work
I have the same problem connecting my QC15 with moto G. With some experimenting I somehow made them work and they are perfectly fine now. Follow the below steps to make them work with your phone.
1. Disconnect the headphones to the phone and start music on any player(Google play or your choice) on the phone.
2. Once the song starts playing insert the headphones into the jack. Imp Note: remove the headset part from the wire.you should only insert the wire without having the headset piece.
3. Now the song will continue to play. Now switch on the headphone and insert the wire into the headphone. It should work now.
I know this shouldn't be the actual scenario, but engineers at Motorola have made up some mess which cannot be cleaned up now with respects to hardware. The phone is little wierd on headphones port. Its not working with aux cables in my car too
I have SMS street by 50 cent and every thing works fine. skip/pause and previous track

Same problem
I've experienced the same problem with Bose QC15 and the Moto G. Motorola support were rude and unhelpful, first assuming that the QC15 were bluetooth and telling me flat out that it was not a fault of their hardware. Eventually I got a ticket raised so we'll see what happens. Not holding my breath.
bonthukarthik, your fix works - thank you for sharing - although I must add that this step has to be repeated whenever playback is stopped or paused (including when Spotify plays an advertisement). If I find anything out from Motorola, I will share it here.
I just got some qc15's and they only worked out of the left ear with the moto x. I used the work around above and they now work. weird. play/pause button now works but the volume does not on the inline headphone controls.
What kind of connector this headset/headphone has?
CTIA or OMTP?
I have skullcandy 2xl single button headphones and it doesn't work
when i attach the headphones the music pauses
Confirmed
I can confirm this issue with Moto X and also the workaround. I have contacted Motorola but so far no luck in getting through to someone who can open an issue internally
Skullcandy not working
Have the same problem
I have the skull candy inkd 2
It only works when its 3/4 inside but when I push it all the way in a clicking noise plays
Please find a solution
Hi.
I just got a moto g, I have a bose qc3 and the same problem.
It seemed tome that it seemed to me that it was connection or impedance related... so I tried a few things.
The best way I found to make it work fast is plugging it in using the airplane jack adapter. It works perfectly fine but the remote won't work.
I guessed that it means that it's remote/impedance related.
Like it was said before, unplugging the jack on your headset, playing something on the phone and plugging it it afterwards works too... But I really don't know why !
Any clues, anyone (with advances electronic skills)?
With my former android phones I had troubles using the answer/play remote on some headphones/buds, but never like that. It was allways clear to me that iphone and android headset/buds remotes work in a different way, and sometimes even differently depending on your android model or brand...
My guess is that using a cable without a remote will work... but it's be nicer to have a working remote.

I found something, just a clue, I don't mean it'll work for sure.

Alright here are some more details / partial solutions :
- If you plug your qc using the jack with the remote/mic and the airplane adpter, the sound sill work, but you'll lose the mic and commands. Basically it's the same as if you plugged it in usgin a "regular" jack cable (that bose sells, or used to, btw)
- if you use the "play and then plug jack in headset" workaround, sound will work, the main button too : it'll play/pause, but if you stop and quit tha music app, the problem will come back
- almost the same with a call, if you call your phone and wait for it to ring before pluging the jack into your hedset the sound will work both sound and mic, but the button fonctions are weird : at first it'll aswer the call, but afterwards it'll work as an on/off switch for the mic.
- Best solution I found : when you plug your headset and have the parasite problem, just press the main button on your remote, it'll stop the problem... but the button won't work anymore, either to answer/hangup or play/pause. I use this solution ftm, even if I don't think it's good for the headset to have this clicking parasite, and I'm still waiting on a way to make everything work all the time.
Any ideas ?

Have you tried with a CTIA to OMTP converter .
Hi, thanks.
No, i should, but I thought that all android phones were ctia now... I don't have my moto handless kit with me, but I'll try it with my gf's xperia sp to see if it works with it, since my bose headset works perfectly with the xperia.
Anyone knows if the moto g is ctia ?
Any other ideas ?

All Stereo Head phones normally use a 3 Pin Jack, Cell phones use a 4 pin, I found this out before with some other audio products..
I confirm all the informations about the problem and the workaround concerning a Moto X and the QC15 I just got. I hope a solution will be found. Does anybody tried that amazon product ?

I have a Droid Maxx and the QC15. The android inline remote & mic kit from Amazon have the same problem as the iphone cable that comes with the QC15 headphones. Quite annoying. Also, I can't get the workaround to work. No matter what I do, I only get sound from the left speaker.
I had a similar problem (no audio, weird noise in right ear) with Moto-G and QC15. The workaround that succeeded for me was to change the headphone gain from Hi to Lo. The gain switch is in the plug that connects the wire to the left earcup.
This supports the suggestion that the issue is caused by some impedance measurement routine on the phone.

USB Audio for TF700

Hi,
I've been looking for a solution to use a dedicated USB soundcard with my TF700, because the sound quality from the 3,5mm analog out isn't loud enough, the quality isn't great and I hear lots of intermittent "hiss" noises when I'm watching movies with DTS sound (whatever the video player I use).
The main problem is the loudness, since I'd like to use the tablet to watch videos i.e. in a plane.
I was thinking of an external USB soundcard like the Asus Xonar U1 or U3 to connect to the dock's USB, but I'd like to know if anyone has tried it before.
Preferably, I'd like something with a dedicated headphone amp.
I have a HiFimeDIY Sabre DAC that kind of works when I plug it in the dock, I hear sounds but with lots of popping and cracking.
Using the USB Audio Player I could make the tablet work correctly with the DAC, but that one only works for music, and their custom driver doesn't work with other apps.
Any help?
(sorry if I posted in the wrong section)
An update:
I went to a store and tried a Xonar U3 connected to a TF700+dock. Same thing as with the Sabre DAC I tried earlier.
Whenever I play something, the sound is "recognizable", but it's mostly made of popping and cracking.
It sounds the same as is I was used the Audio Player before applying the proper settings (force 1-bit, 16bit sampling, 4k buffer).
This seems to be a driver issue. I heard Samsung phones/tablets work flawlessly with most external USB DACs, so this is a real shame.
Why don't you get a Fiio amp?

Moto G Earphones Disconnects Continuously After Rooting It

moto G earphones disconnects continuously
Hi.
I have this issue with ear phones. I use Sony MDREX110APLIE Wired Headset. I recently Rooted my device and I guess i dropped the phone once after rooting.
Whenever I try to use my earphones ( For calling/ music/ FM radio) It seems to get disconnected after running for like 2 seconds... I tried to use my earphones on other devices and it works fine... I have also tried using other earphones on my device and it still has the same problem :/
So can anyone tell me if this is a software issue ( Something like a kernel that i have to flash after rooting) or is it just simple hardware audio Jack issue. Is there a way to check if it is a software issue?
Thank you for any comments

Calling with USB C Earphones?

Hi,
So bought these awesome Razer USB C earphones which have a built in mic. They work fine as both earphones and a microphone but for some reason the native phone app will not route the call audio through them!
I have no doubt this is a quick fix for Samsung kernel or otherwise as they remove the USB port from the next generation of phones but I would expect USB C earphones to work. Other phones like Oppus, Huwei, HTC and Pixel don't seem to have issues.
Any ideas here?
I have the OnePlus USB-C Bullet earphone, it works fine both for audio and for a call.
I've been trying my old HTC headphones I got with the U11. Sadly these don't work at all as they are brilliant headphones.
Probably because of the active noise cancelation they need a specific driver.
Okay, will return and try these instead.

The OnePlus USB-C earphones didn't work with my Note 9 either. At least these are cheaper...
I believe some of those headsets use a analog pass trough instead of having their own DAC so they only work with a phone that supports that

Note 9 - USB C Headphone Support

Hi,
Let's start a USB C earphone support thread. So far I've tried the following, without full support:
- Razer Hammerhead, Music Yes, Microphone in Recorder Yes, Calls No
- OnePlus Bullets, Music Yes, Recorder Yes, Calls No
I'm starting to think all USB C headphones are going to be like this on the Note 9... Surprised they haven't updated the source to support these kinds of headphones ahead of the Note 10 and it's lack of 3.5mm port.
Same problem
Same problem here. No solution so far. Going to take these things back.

I'm thinking they don't see a reason to have usb c headphone fully supported on the Note 9 because it actually has a 3.5mm port? We all know Samsung is the last to adopt certain things. It would be nice if they did support it though because the range of possibilities would be more for listening to music. Headphone Jack busted...not a problem, use usb c port etc.
Xiaomi ANC HiRes audio type C earphones, not working at all
I've tried Google's for pixel 3 earphones. Music and control (including mic on recorder) yes, phone calls no. But I must say: the sound through these earphones surpasses anything I've tried on my note 9. Even without phone call function the quality of music coming out of these earphones is worth it!
HTC U-Sonic USB-C earbuds are a no-go all the way around on both the Note 9 & Note FE.
The Developer Options on the Note FE even has an audio source option in the USB Configuration section & still nothing.
IIRC, the HTC USB-C buds were one of the earliest models available & may have been proprietary to HTC phones.
I have got them to work on a few non-HTC phones along the way, but, Samsung isn't one of 'em (OnePlus/BlackShark/RazerPhone come to mind,IIRC).
Sent from my Note Fan Edition using XDA Labs
I wouldn't be surprised if the Note 9, 8 and FE don't support the use of USB Type-C headsets for calling.
I use a Lenovo USB-C hub that I plug my Astro Mixamp into and listen to music.
I can't get phone calls to work tho.
i tried plugging note 10 C headphone to my note 9 so it is just able to hear music but can not answer the call. However, the C headphone did on my S10e.
OnePlus Type-C Bullets work!
Hey everybody! I just came on to search whether or not my type C bullets from my OnePlus 6t would work on the Note 9 I just got. Before plugging them in, I went into developer options and unchecked "Disable USB audio routing". Plugged them in and the sound incredible! The in-line volume, play and pise functions on the Bullets work as well. However, attempted to make a phone call and it just stayed defaulted to the phones earpiece with the Bluetooth or speaker phone option. Anyway, just thought I'd share my experience a few moments ago lol. Yes it would be great if we could get these to work with a simple phone call. Hate to just put these Bullets in a drawer to collect dust until the day they are supported by a phone I own lol.

Yes, they do work for listenning, with volume and pause/resume buttons. They don't work for call though.
Something changed in Android 10? On apk mirror is samsung usbc headset app/driver but its not working :/
Couldn't find developer options
Hi, I tried what you recommended. I couldn't find developer options except under accessibility. It didn't have remove audio routing. I have a note 9

Correct. I also tried on a Corsair G935 and audio works but phone calls do it. Tried it on my Note 10 and if works just fine for calls.
Thinking this might be a hardware and not a software issue.

Okay so i know this thread was started a while back, I just wanna say for any new Googler's that the Note 9 cannot support calls because it has the 3.5mm ear jack which handles all the analogue sounds means phone calls, "Hey Google" and similar cannot be passed through the Type C headsets/headphones. Its hardware so no apps can help with that.
