Mixer Paths Edits

Any ideas where the bluetooth edits are for limiting max headphone volume?

Will the A2 support (or drive) Audio Technica ATH-M30X headphones?

From their website under the specification section the impedance of these headphones is 47 ohm. In general what level of impedance A2 can drive comfortably?

Well.. I had a bad experience with the sound for this phone.. with the dongle or via Bluetooth.. I have M50x and Mpow headphones (decent for the price).
M50x with Havoc 2.5 above 90% volume starts introducing noise..
Mpow still not tested in 2.5 but in 2.4 the connection was weak and there was a lot lack of sound richness.
Edit: Just installed ViPR4Android FX from Magisk and after tweaking a little bit you can get a decent audio quality from the Mi A2 with mid/hi end headphones..

bluetooth max volume

volume on my bluetooth headsets is limited although I enabled "Disable absolute volume" - any suggestions.
They used to work at much higher volumes
TIA

Try RE equaliser from the playstore.
It allows you to increase the gain and is a ten band equaliser.
Just remember to turn off any other equalisers that you use.
Go into the settings and you have an option to make it work for Bluetooth and wired headsets.

Quad DAC tweak finally achieved.

Just need to plug in a DUNU 3.5mm to 3.5mm impedance adapter (75ohm) into a 3.5mm AUX extension adapter, then plug it into your headphone jack.
Then remove the DUNU impedance adapter and plug in headphones. You can change the headphones but leave the extension adapter and it'll stay in high impedance mode.
This worked with the V60 as well before I had to return it due to it being defective. I'll buy another eventually.

That only gets it into aux mode so it's louder but the sound quality is not improved, I'm getting high impedance with my method.

I don't currently use any headphones that need the boost, but I'll definitely keep this in mind. Thanks!

If your headphones have removable cables, you can, with both unplugged, plug the audio cable into the phone. Then go ahead and plug the other end back into your headphones, and this will trick your phone into giving you the full power DAC. This works. It's hilarious but it works.

in v30 i used just those lines
<!-- ESS DAC START -->
<path name="headphones-hifi-dac">
<ctl name="Es9018 AVC Volume" value="0" />
<ctl name="Es9018 Master Volume" value="0" />
<ctl name="Es9018 HEADSET TYPE" value="2" />
</path>

and that bring me HIGH GAIN mode and not Aux, that is worser.
Here in G8/v50 there is same file in vendor/etc ...called as mixer_path_blablabla
Found same lines about Dac and this doesnt helped at all. Need to find out, coz dont wanna use this tricks with wires, prefer to use phone at the maximum, i paid for this.

okay i found out. There is in Product/OP/Audio/mixer_paths_tavil ... need to find lines for ESS DAC START
<!-- ESS DAC START -->
<path name="headphones-hifi-dac">
<ctl name="Es9018 AVC Volume" value="0" />
<ctl name="Es9018 Master Volume" value="0" />
<ctl name="Es9018 HEADSET TYPE" value="2" />
</path>

maybe in vendor/etc need to find same file and make same changes, not sure, did it in both
It was better than AUX mod, that can be done with wires.

That's a cool little trick! Thank you.

I have a problem, I own Lenovo HE05 and that stupid blutooth headphone has that output channel is SBC only and I'm unable to do anything about it
it's stereo output is reversed, the L is R and the R is the L so please help me.
P.S: and also I have no idea where's the damn mixer path and I'm unable to Root the thing.
