When playing audio off the the USB-c output on the nothing phone 2, the phone will output music with static in the background, it will be most noticable at the extremeties 1 audio notch or max volume but can be heard no matter the audio level.

Something is wrong with the signal output. I havent tested it with the apple dongle yet will do soon, but the one all the audiophiles recommend (ones with the CX31993 dac chip like the abigail pro) doesnt play nicely with the nothing phone 2.

The issue is with the phone itself as I have tested it on a oneplus 5t and my desktop which don’t exhibit static when using this dongle. Could this issue be looked into please? it makes wired audio listening very unpleasant with the background static.

Update:

So this issue still persists and using this phone with any dac dongle isnt a very good experience.

There is a partial solution though as mentioned by hamlinstephen, Use a USB C to 3.5mm dongle that does NOT have a built in DAC chip, this will work without introducing the static. They’re a bit rarer to find these days, but I found one on amazon from UGREEN that works just fine for £6.

    I am facing the exact same issue with my Nothing phone (2) . I used 2 earphones , 1. 7HZ Salnotes Zero (USB C version) , 2. KZ ZXT 3.5 mm attached to a USB C DAC ( Abigail) . Both gave crackling sound and the sound quality overall is really really bad . I connected the same earphones to my laptop, and the sound is crystal clear. Also, with nothing phone (2) my Bluetooth headphones are giving a good sound . I can’t seem to find any solution to this issue on online forums .

    Hello,

    I am facing a similar issue with my Nothing phone (2) with OS2.5 .

    I can hear static white noise in the background when using a passive USB-C audio converter with my moondrop aria iems (TRS plug). Also tried with generic iem with TRRS plug and face the same issue.

    Hi there!

    Problem with static still persisting as of 1 Mars 2024.

    Also when connected through USB C to USB C headphones (e.g bowers & Wilkins px7 s2), the volume as compared to Bluetooth is really really low. Bluetooth is really loud at 50% or so while wired is passable/fine at 85-90% but never really gets “loud”. Unsure if it has to do with aptx codecs boosting volume or if the USB C output from the phone 2 is just really weak or if it is some other software related issue. Would appreciate someone looking into it.

    Thanks & have a wonderful day.

    I also have dongle based on cx31993 and while I don’t hear the static on the output I have very loud static hiss on the input, so loud that I barely hear the mic. And the hiss is here no matter if headphones are plugged to DAC or not. I tested the DAC on pc and Samsung phone and there were no problems. Issue seems to be present only on my Nothing Phone 2a. Do you have this issue on your DACs and phones?

      I have the same issue with my usb c to 3.5mm jack dongle with DAC and AMP when connected to Nothing Phone 2a. The audio output is working well but the input mic isn’t working. There’s just static when recording anything.

      The dongle is working fine when connected to other devices

      Same Problem in my Nothing Phone 2A i recently purchased a DAC type c to 3.5 mm jack but the micro Phone is not working. The moment I connect the converter a constant humming crackling or humming noise is picked up by every app that uses microphone. The connector works fine with every other device i tested it with, which is so annoying. Not only does this phone performs less in Antutu Scores from it’s competetor with same chipset but now this problem. May be purchasing this device was one of my worst decision ever.

      In the latest update, the problem was fixed partly. The audio is being recorded but it’s not usable most of the times. Too much disturbance along with the recorded audio.

      Rockett have you disabled dirac in sound options? Makes every USB DAC I’ve connected to the phone sound like absolute crap, including my jcally cx31xxx

          I didn’t hear much difference. The crackling in the voice recording is present with it disabled as well.

          The microphone-recorded voice quality is very bad in Nothing Phone 2, even after several updates. I already tried a Type C to 3.5 converter with DAC, a Type C to 3.5 converter without DAC, and a Type C headphone without DAC so far. The converter and Type C headphones without DAC is slightly better but NOT AT ALL useful. The recorded voice is such that some noise cancellation or something filters part of the voice. All these work well on devices from other manufacturers (old as well as new) without any issues. So, I am very convinced that it has to do with the hardware or the software of the Nothing Phone 2 device itself.

          It tried this yes and I didnt notice a difference on or off, static was still there.

            MrMightyBun Hi mate, I’m facing the same issue. I bought Fiio JD 1 Type C IEM for my CMF PHONE 1. I heard a loud static whenever I activated google assistant or while I receive a notification. I returned it and I’m thinking to buy a Moon drop Chu II Type C IEM. I’m not sure whether the issue would be present again.
