Christine_ASUSHi @Christine_ASUSThank you for your asking. Does the situation remain the same in different cable earphones?
If you prefer Android 9 audio performance with your earphones, you may follow the steps below as 10 to 9 downgrade steps.
1. Download "Version MaxProM1_downgrade_to_9" and then put the image file into the root directory of the MicroSD card.

3. Long press with "Power" key and "Volume Down" key together and stop after feel the vibration to enter Recovery Mode
4. Use "Volume Down/Up" key and press "Power" key to choose "Apply update from external storage"
5. Select the downgrade file
6. When the updating process is done, Choose "Wipe data/factory reset" and tap"Yes" to perform the master clear.

akshay.ruparelIf you only have sound issue, you can check “ADB commands” solutions on YouTube.https://zentalk.asus.com/en/discussion/comment/144566#Comment_144566
Thanks for replying.
Apart from audio, I really do like the other features that android 10 brings (v438) .
So currently in a dilemma on downgrading.
I love the audio performance of android 9(via Aux) .
Can you please confirm if the wired audio output will be improving in the next beta/stable update?

The system maintenance of this device is probably finished. A device normally is taken care of for 18 months, and MPM1 had been maintained for 32 months since 2018.
