Low quality sound and minimum volume is too loud on headphones about lineageos-releases HOT 7 CLOSED

Yeah I just looked up the EvoX's xml file and that part is same. My stupid guesses:

• IDK how xml works but maybe this settings in xml file was overridden by another value.
• Until now that line couldn't even read by old android versions and with Android 12/11 someone fixed some code and now it is actually read.

There is a chance this issue isn't generic because I have I(AU) model not F(EU) and highly possible other guy in the thread has the same model

check latest build

from lineageos-releases.

UPDATE: I found a fix until fixed in the main build, thanks to those reference posts: this post by west0ne, this post by qasdfdsaq and this issue by Fabrice Bellet

1. find the gain-media-headset on /system/vendor/etc/mixer_paths_0.xml

2. change the content

• old content:

  <path name="gain-media-headset">
      <ctl name="Noise Gate Switch" value="0" />
      <ctl name="HPOUT1L Impedance Volume" value="113" />
      <ctl name="HPOUT1R Impedance Volume" value="113" />
      <ctl name="HPOUT1L Input 1 Volume" value="32" />
      <ctl name="HPOUT1R Input 1 Volume" value="32" />
  </path>

• new content:

  <path name="gain-media-headset">
      <ctl name="Noise Gate Switch" value="0" />
      <ctl name="HPOUT1L Impedance Volume" value="70" />
      <ctl name="HPOUT1R Impedance Volume" value="70" />
      <ctl name="HPOUT1L Input 1 Volume" value="26" />
      <ctl name="HPOUT1R Input 1 Volume" value="26" />
  </path>

  I changed the Impedance value from 113 to 70 distortion, loudness and white noise totally gone 😌
  and tweaked Input 1 Volume to my liking while checking the minimum and maximum headphone volume.

3. after the saving content, kill the audioserver:

adb shell
su
pkill audioserver

edit: typo on the xml path

Thanks for the report.

I will look into it. AFAIK this is the same mixer_paths that is used in EvoX, so not sure why theres an issue suddenly. But if this fixes it, I will probably just use this as the solution as long as everything goes well in my testing.

Actually I also faced same issue with F model, I read your issue earlier but I faced the issue now, so I'll wait for the new build or I'll try the manual fix. Thanks..

70 is too low on all kinds of headsets, kindly increase to atleast 90 or 95 minimum... I always change it aftrr updating.

For anyone who feels it is still high can keep volume at 90 percent..

Thank you.
