Sound sometimes only comes out of right speaker

However, if I use the sound balance app and move it anywhere (then back to center), the left channel returns.
Basically, it's not an issue with the left speaker or the cabling.
This is what About says for my Dicola CHS7047X:
Manufacturer: rockchip
Model number: PX5
Android version: 8.0.0
Android security patch level: October 5, 2017
Kernel version: 4.4.93+; [email protected] #121; Fri Jan 26 10:41:07 CST 2018
Build number: px5-userdebug 8.0.0 OPG5.170623.007 eng.hct.20180126.113204 test-keys
MCU version: MTCE_CHS_V2.76_1; Dec 20 2017 15:49:46
CPU: 8 core 64-bit CPU Coretex-A53 @ 1.5G
Any ideas?

I sometimes have the same problem. Does anyone have a solution?

OMG.. yes! I thought I was the only one with this issue.
Bugged me for a long while. I do have a workaround which prevents this issues from cropping up (works for me at least).
If your fader is set to dead centre, this issue does not occur.
Since I wanna run only my front speakers, I have disconnected my rear speakers. Try it, lemme know how it goes.
Edit: I am using Daisata, PX5 Android 6.0. Updating to latest MCU didnt help.

Calls muted when car in reverse

Good morning.
I have an SYGAV /Dasaito Android 9 head unit...
Model: PX6 (1024x600)
Build: rk3399-userdebug 9 PQ2A.190305.002 20190611.144108 test-keys
Kernel: 4.4167 #320
Calls and other audio sources are muted when the car is in reverse and the backup camera is activated.
How can I change this default behavior so that at least the calls aren't muted?
Thanks in advance!

Look in your factory settings on the last tab, disable reverse volume and it should work fine.

Erisin PX5,Android 9.0 Bluetooth issues

Hi,
I was wondering if I could get some help with my issue. I bought an Erisin ES8049U head unit that I am trying to connect to my cars after market engine management system via Bluetooth. The head unit discovers the engine management system but it's quite troublesome to connect to it. Sometimes it connects, sometimes it doesnt. The Bluetooth connection to the cars engine management unit works fine from my Samsung mobile, so the problem is in the Erisin head unit.
Also when I finally get it to connect, no data comes through to the engine management system, it's like its not even connected and sometimes it flashes connected/disconnected.
Here are the info on the system:
PX5
Android 9
Build: rk3368-userdebug 9PQ2A. 190305.002 20191113.183229 test-keys
Kernel: 4.4.167
MCU: MTCE_LM_V3.43_1 / DEC 17.2019
CPU: Octa-core Cortex-A53 @ 1.5G
BT chip that has been selected in the system by default is: SD-8350
I've read some of the BT connectivity issues and they mostly have had different BT chips installed, at least originally. Any idea which chip I could test from the list, or is there a MCU that would fix connectivity issues? Or any other things I could do?

OK, I got it to show the data from the engine managament unit when I disabled Wireless and after that it started connecting. But if I restart the car, it doesnt want to connect to the application. With my phone it works flawlessly. I wonder if it's an application error or something to do with the head unit.

A-MEDIA AUTO MTCE_CHS_V3.76_1 Bluetooth Problem

HI all, I have a problem with Bluetooth on the following A-MEDIA AUTO head unit:
Model
PX6(1280x720)
Android version 10
Build number rk3399-userdebug 10 QQ2A.200305.004.A1 eng.hct.20210902163038 test-keys
Kernel version
4.19_111+
#158 Wed Aug 11 15:57:41 CST 2021
MCU version
MTCE_CHS_V3.76_1
May 13 2021 15:42:50
CPU
Dual-core Cortex-A72 @ 1.8G
Quad-core Cortex-A53 @ 1.5G
Memory
3841MB
I know Bluetooth problems appear to be legion on these Chinese head units, but maybe someone can help me sort this out. Now there is no problem pairing any device with a PIN: mobile phones and OBD2 dongles pair up just fine. But I have a lot of Bluetooth devices and applications that communicate directly - no pairing required - such as battery monitors, BMSs, mobile phone repeater units. These devices/applications used to work on my old Android 9 head unit (different chipset entirely), but now on this new Rockchip 3399 Android 10 unit, none of them can communicate at all.
I'm not sure if it's an Android 10 problem, or (more likely I suspect) a broken Bluetooth implementation in the MCU. Another problem is that audio pass-through from the mobile phone doesn't work at all, even though all other phone operations work as they should.
The Bluetooth driver setting in the unit is set to WQ_RF210. I've tried all of the other settings for fun, but of course there was no improvement.
Is anyone able to shed any light on this?

IDOING PX6 Pro zlink freezing problem

Hello, I have an IDOING ROCKCHIP PX6 radio ( https://es.aliexpress.com/item/1005001556699902.html?spm=a2g0o.order_list . order_ list_main.74.21ef194dVBJqix& gatewayAdapt=glo2esp )
I am having problems with the ZLINK version 5.3 app that when I connect to my android phone wirelessly it freezes the image every 50 seconds and then refreshes again. Sometimes it doesn't update right away and I have to go back to the start menu and open the android auto app again.
Complaining to idoing via aliexpress I no longer have support and a solution on their side since I have to send the radio to China and the cost is higher than the radio, could you help me solve my problem
I am afraid of making a bad update and the radio will go black without recovering it
if you can help me

Try using unit without using the known buggy Android auto emulator, alternatively you probably want consider buying an official Android-auto head unit
