Dual Speaker Mod (G935T)

[qwewqa]

Features:

• Activates the front facing (handset) speaker during media playback, enhancing audio quality.

Installation:

1. Have your phone on and plugged in to your computer. (It should be running G935TUVU4APIA, I haven't tested in other versions. Root needed.)
2. Download and extract the attached zip (Do this on a computer)
3. Run install.bat (Windows)

Restoring Previous Mixer Paths:

1. Same as above but run restore.bat instead of install.bat (The install script creates a backup)

More Information:

To Adjust Handset Volume:

Find the below lines:

    <path name="spk-mono">
        <ctl name="PRI_MI2S SampleRate" value="KHZ_48" />
        <ctl name="SLIM_0_RX SampleRate" value="KHZ_48" />
        <ctl name="One Stop Mode" value="Mono Left" />
        <ctl name="SLIM_0_RX Channels" value="One" />
        <ctl name="SLIM RX0 MUX" value="AIF3_PB" />
        <ctl name="RX INT0_1 MIX1 INP0" value="RX0" />
        <ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX0" />

        <ctl name="RX0 Digital Volume" value="[B]93[/B]" />
    </path>

    <path name="spk-mono-44.1">
        <ctl name="PRI_MI2S SampleRate" value="KHZ_44P1" />
        <ctl name="SLIM_0_RX SampleRate" value="KHZ_44P1" />
        <ctl name="One Stop Mode" value="Mono Left" />
        <ctl name="SLIM_0_RX Channels" value="One" />
        <ctl name="SLIM RX0 MUX" value="AIF3_PB" />
        <ctl name="RX INT0_1 MIX1 INP0" value="RX0" />
        <ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX0" />

        <ctl name="EAR PA Gain" value="POS_6_DB" />
        <ctl name="RX0 Mix Digital Volume" value="[B]93[/B]" />
    </path>

And change the bold numbers. (I would recommend values between 90 and 95)

Yes, you need root.

Does it have a static issue?

No, it does not have static.

Worth a try.

Just installed onto the latest Echoe ROM 1.5 with mixed results. It plays out of both speakers when playing the boot animation sound, and then system sounds (lock screen, notifications, ringtone, etc) play through both, but nothing else seems to work.

Hmm. I'm using Echoe 1.4.1 and videos work but not from Youtube or music apps. But it does work... somewhat.

It works for all audio for me. I'm running stock, but I don't think using a custom rom would be the problem. Could you try rebooting and not using the phone for five minutes first, that has been a problem occasional for me. I'm somewhat busy during the week, so I'll try to fix some things over the weekend.
(ps: VLC may work for music.)

Hello friend, install it and does not work, I set permissions are not equal to other files, you have to change the permissions? Thanks & best regards!

Do only some sounds work, or do none of the sounds come out of the handset speaker?

 

[rubendario067]

Just of make an installation clean of the rom, by the time when it turn on if sounds the speaker front, but YouTube does not.

Well then, I guess I'll be testing with the Echoe rom this weekend.

This ECHOE ?

[twe90kid]

Seems to work for dual speaker. Anyway we can make it much louder?

 

[cjlopez213]

This is awesome! Running this with PD8 on a standard S7 with the ECHOE rom.

*Also it even works with YouTube! Thank you!

Is there a possibility this could work on the AT&T variant?

Would this technically work on the flat S7?

You could try it, it should work, but I can't test

Unfortunately, it didn't work. I'm running the Echoe ROM and the sound is only playing through the bottom speaker. I was really hoping it would work since there is hardly any development on the AT&T side....
