In fact, the headset speaker doesn't sound a lot by default. If you put your ear close enough you will hear that now it produces sound, but it is around 5% loud compared to the bottom speaker.

You can install the app Viper4Android that DorianX offers along with the stereo speakers mod (install it via TWRP) and then activated it via Magisk. After rebooting the phone, you can go to Viper4Android,->Phone Speaker->Master Power (ON) + Master Gate (Limiter) increase the Output Gain.

It worked for me but, still I am not impressed with the loudness of the Phone Speaker, obviously it is not meant to be used as a normal speaker for media consumption, but still provides enough sound to fill in the front side of the screen which sounds directly to the viewer, compared to the single (before the mod) bottom speaker. (please somebody to correct me If my procedure is wrong or not the ideal one).

Hope the above are helpful enough ;)

One question for Dorian:

Every time I start the Viper app, it asks for the V4A driver installation. I installs it properly, asks for reboot but every time after the reboot it asks again for the driver. What am I doing wrong?

Thank you :)

Really weird thing happened to me. Have been using the mod for a couple of weeks, then it like 'disappeared'. Reinstalling, using both Magisk and TWRP, reverting to stock, full wiping, changing kernels, ROMs, nothing helped. Do you guys have any ideas?

Anyone have issues with the audio while recording video in Snapchat and Instagram? After flashing revert and replacing stock xml file I'm still not able to record video in these apps but camera app is fine. It is like a loud crack at the start of the video and then silence.

What is the difference between the Viper4 MOD (that you modified to support stereo) and regular replacing of mixer file?

If I have Viper4 already installed. Should I only replace the xml file and then import your Viper4 profiles?

Some times doesn't work on some apps, a workaround is using Viper4android disabling then enabling again.

strange enough, it worked for me with magisk.

But .zip old version won't work, only the one for oreo.

Some music app won't work with ''stereo speaker''

Youtube is working. So try it. Note that the sound is very low, it's not what you can expect from a ''stereo speaker''.

In fact, its NOT even real stereo, it's mono or mixed stereo, and both speaker play the same thing.

[OnePlus 5 Themes, Apps, and Mods] dlads:
I'm going to take a risk, my earpiece is very low, I think broken, I've never installed this mod, but I'm going to now, I'm hoping the higher volume allows the speaker to potentially shake whatever is on it off.

I've tried raising the mixer path audio, , bluetac on the grill, toothbrush, compressed air.

Still hear people just very low. Pretty sure it's hardware and needs RMA, let's see what happens with this mod. Fingers crossed.

[OnePlus 5 Themes, Apps, and Mods] RogerF81:
Did it work, or is your earpiece broken?
[OnePlus 5 Themes, Apps, and Mods] dlads:
Nah it is broken pal, apparently it's quite common, editing mixer_paths_tasha.xml didn't change anything either.

I've took the phone apart, very easy to be honest.

Cleaned the earpiece and contacts but it's the same.

Have ordered another from eBay, decent supplier, should be here in a few days, I'll fit it and let you know..

Fingers crossed, if not I'll grab a tamper sticker from eBay and RMA it.

Got an upgrade soon too, just wanted to keep it a while longer.
[OnePlus 5 Themes, Apps, and Mods] RogerF81:
Sorry to hear that :/ so to RMA it is a good desicion I would say. And thanks, I'm quite curious about what will happen then!

What did you get as upgrade?
[OnePlus 5 Themes, Apps, and Mods] dlads:
Nah I've ordered the part, I don't want to send it off and get some half arsed refurb as my phone, the battery I've tested very well and it's a day one phone so would prefer to keep it.

If it fails after the earpiece replacement I'll RMA it. But I'm guessing it'll be fine.
[OnePlus 5 Themes, Apps, and Mods] RogerF81:
Ok I see. Do you use stock rom or anything else btw?
[OnePlus 5 Themes, Apps, and Mods] dlads:
I always use a custom rom, currently running No Limits which is superb.

I changed over the earpiece, bought this one from

eBay https://www.ebay.co.uk/itm/For-OneP...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

This particular piece although it says A5000 - Oneplus 5 it was about 2mm smaller than the original earpiece in place.

I cranked the metal contacts and managed to get audio from it, but the audio was on par with the previous earpiece so i'm now thinking it's either something which was left within the root of one of the files for the phone like mixer paths or another piece of hardware.

I'll reflash xXx 9.5 and clear out the phone and see how it goes, not happy at the moment.
[OnePlus 5 Themes, Apps, and Mods] RogerF81:
I see, I thought you would use an AOSP Rom ;)

Oh ****, yeah, hopefully this is only a software and no further hardware issue.
[OnePlus 5 Themes, Apps, and Mods] dlads:
Aye fingers crossed, but it's anyones guess at this point, i'm sceptical about it being software.
[OnePlus 5 Themes, Apps, and Mods] RogerF81:
Yeah seems to be something hardware related, but hopefully not.
[OnePlus 5 Themes, Apps, and Mods] dlads:
yep the same thing again :(

Need to at least try to boost the volume, any idea what to edit to just make the earpiece louder?

I've read it's mixer_paths_tasha.xml and edit a line within there called dx7 i think.

Can anyone clarify?

Cheers.

You won't get to know if it's working fine or not until you play something on your phone. For example, it works while streaming videos on the YouTube app. Try that after flashing the zip in TWRP. If you listen carefully, you'll see that the audio output is also coming from the earpiece headset in addition to the bottom firing speakers and that's when you'll know that the mod has worked. :)
