Works great on my H818P. Thanks so much for the detailed guide!

Correct Mixer Path Values for 818P?

Edit 1 - Cleaned up my post and added some values. Also, can someone test these values? All you have to do is change the RX1 and RX2 values under them to 0 and check if you can let any sound come out of it based on the description. I don't have the necessary hardware to do these.

2484 <path name="headphones-advanced"> - Bluetooth headphones
2492 <path name="headphones-aux"> - When device is connected as an auxiliary device via a 3.5mm audio cable.
2500<path name="voice-headphones-advanced"> - Bluetooth headphones in call volume.

Hey everyone. So I've been dabbling with this mod for the past few weeks and to be honest, I didn't notice any difference in the sound volume. To be fair, my hearing is not what I would consider stellar so instead of guessing if it was working or not (I felt like it wasn't), I decided to do a little test.

Instead of increasing the volume, I decided to try and mute it. I changed the values described in the opening post to 0 and it had no effect. So I went about looking through numerous threads, changing values to 0 until a value actually muted it. I've gone through several values to identify which ones control which volumes. In my mixer_paths.xml, I found these lines:

1549 <path name="headphones"> -[U] Headphones/Headset[/U]
1575 <path name="voice-handset"> - [U]In call volume for phone's earpiece[/U]
1601 <path name="voice-headphones"> - [U]In call volume through headphones/headset[/U]

and changed the RX1 and RX2 values under them to 0. Voila, all sounds going to the respective descriptions were gone. So i decided to now increase the values.

I initially tried to increase it to 109 (about 30%). I couln't go past about 60% on my phone's volume without feeling like I'd be deaf. I then tried 101 (about 20%).

It's still a little too strong but I'm going to experiment with it a little more to find a value that suits me and my poor hearing.

So my question is is this. Is it different for other variants?

The idea of modifying said value came from here.

Thanks for sharing. I too found no difference in the changes that worked on my G2, nor what's posted here. I'll try this and see when I get some time because this phone's loud enough for me except on headphones.

No worries. Let me know how it goes. By the way, which variant are you using?

 

[jesssiii]

G4

 

[Usraek]

This guide I posted is for the G4 after testing *many* lines (each requiring a reboot).

I would have thought that all the variants would be pretty much the same?


Man the sound of the G4 is just horrific. No matter what I do it sounds gross, and I'm highly debating carrying along my old S3 as an MP3 player. It's just really disappointing plugging my headphones in every time...

I initially thought so too. But when I wasn't noticing any improvements, I just went and thought to myself that I'll go ahead and 0 out values until I confirm which one mutes it (Also rebooting each time). I found the values I mentioned above to mute it, increased it and voila, louder sound. Can you try it out by muting on your end as well? I guess each variant has its own value that needs to be edited. I'm using the 818p by the way.

I agree. Loudness is the only thing we can change so I went with that. Or maybe we're just used to Boeffla Sound?

 

[oreo27]

Edited my post. Can someone check out these changes to confirm if it's working?

2484 <path name="headphones-advanced"> - Bluetooth headphones
2492 <path name="headphones-aux"> - When device is connected as an auxiliary device via a 3.5mm audio cable.
2500<path name="voice-headphones-advanced"> - Bluetooth headphones in call volume.

I've confirmed these ones myself:

1549 <path name="headphones"> -[U] Headphones/Headset[/U]
1575 <path name="voice-handset"> - [U]In call volume for phone's earpiece[/U]
1601 <path name="voice-headphones"> - [U]In call volume through headphones/headset[/U]

As per the opening post, change the RX1 and RX2 values.

You have the dual sim model, right? It seems to have some strange little differences, but the guy right above your post said it worked on his lol.

I checked my values and they do mute when I put them to 0, so I'm not sure.

I would check your other ones but I don't have any bluetooth audio devices.

Cheers

Yes, I do have the 818P. Well, it could be a similar placebo effect that I too was experiencing prior to trying to look for the correct values. I suppose that confirms it. Either different models or different software versions are affecting this file. I'm on v10F.

Neither do I. I suppose when someone comes around the thread with a Bluetooth device, they could try it out for us. :highfive:

 

[slonn]

When I wrote that it works on my h818p that was only for loudness. I haven't tested it for bluetooth and such af I was only interested in increasing the sound level. Never use bluetooth so no bother there

 

[slonn]

Noticed that the mod has stopped working. I haven't made any other modifications, only thing i can think of is that FX explorer had been updated. Could that affect the mod?

I'm sorry, I'm not too certain. I just had to do the mod again myself due to receiving my device back from warranty work (again) and it all is functioning okay.

Tried on my H818N..... works like charm... thx a ton.......:good:

No worries. Glad to hear it's not just me. Which parameter did you change?

The one mentioned in the OP.... set it to 92........

Changed all the RX1 / RX2 from 88/84/81 (defaults) to 92. Seems to be working fine.
