[Q] Wifi Calling - Incoming Audio Very Quiet - Samsung Epic 4G Touch

I've tried both GrooveIP and Talkatone, and both apps result in very quiet incoming audio. I have no complaints from the person on the other end hearing me, but I can barely hear them. Going into the settings of each program and boosting the speaker gain helps a little, but hinders audio quality. Even using the gain boost in each program has little effect on the earpiece volume (using the earpiece on the phone).
Is there another setting in either app or on the phone itself I might be missing? I am on an Epic 4G Touch running PhantomPhreak's CM10 ROM.

I found a solution. It seems odd, but I'm not complaining. It works. Using Talkatone, I went into the call settings and changed the "audio playback stream" from voice call to music. I noticed by changing this, it also deselected the hardware echo cancellation. It's odd changing this setting makes callers go from nearly inaudible because the sound is so quiet to being nearly like a normal non-wifi call. If I had to guess, the Epic 4g touch has no hardware echo cancellation or it isn't compatible with Talkatone if it does. In any case, I'm happy I can use wifi calling and finally hear the other person.

[Q] Earpiece buzzing at louder volumes

Has anyone else experienced a problem where the earpiece buzzes when the volume reached a high enough level? For me it happens during the loud part of a word when someone is talking (typically the beginning to the middle of the word), and on the highest two in-call volume settings. I can crank it down two notches and the issue disappears, but it just seems unlikely to me that the highest two settings would be unusable.
I got the same issue too, but only with certain callers though. The worst is when I call *611 to Verizon customer service and listen through the automated rep/music. It would create a buzz or static/distortion sound in the earpiece. Kinda annoying, but luckily I use the bluetooth headset 99% of the time. I just tested the earpiece today on a normal call and can confirm to you that I got similar problem, but again on certain callers only.
Can anybody else confirm this?

Groove IP Users (VOIP over Google Voice)

What setting have you found that work well for you? Callers are reporting horrible echos, and I can't seem to work them out.
Also, does't really work at all over 4G, I can hear them fine, but my voice cuts in and out. Tested it while getting 20/16 with 30ms pings.
I am using it with the GSM GN on T-Mo and have had no complaints on 3G/H+/WiFi.
I have Echo Cancellation enabled + Post Processing and Auto detect for the Echo Tail
Speaker Volume at +1
Mic Gain at -2(default)
Yeah, I'm having the same problems. I've tried GrooveIP on my GN using my home wi-fi and Talkatone (iOS5 app that does the same thing) on my iPad 2 and Talkatone is much clearer without tweaking any of the settings.

Click to expand...
Click to collapse
I had to boost the mic gain so the caller could hear me at all, now they can sorta hear me...but their voice echos like nuts (on their end)

[Q] Issues with Volume gain being too loud

Edit: Well nevermind I seem to have fixed it. I thought it was the gain, but as it turns out I had the Noise Filtering option checked. The audio quality in calls is clear as mud now.

Calls fading in and ou when using speakerphone

Hi, there.
I've using my S9 for a couple of weeks now and I noticed a very annoying problem.
If I'm on a call (phone call, video call, regardless the app), using the speakerphone completely ruins it. On a video call it's easier to feel the problem: you can still see me talking, but you can't hear anything. The voice keeps fading out and back in and out again, like the volume was lowered and put back to normal. It's basically impossible to understand anything. Quality of the image is fine, it's smooth, not pixelated, but the voice is just terrible.
If I use the earpiece or wired phones (have not tried with BT yet) this problem doesn't happen.
I have the feeling that this has to do with the noise cancelling trying to filter out the noise.
When calling my wife (Xiaomi Mi A1), it also happens from her side to the point where we can't do video calls anymore. If I call my sister (iPhone 7), the audio is just fine for the same app and on a video call.
I have the feeling that this is a known issue, but I couldn't find a post about it.

Echo on messaging voice calls (whatsapp, kakaotalk)

Hey, did a search but didn't see anything. I have a G7 running ULM20e (sprint cross flashed).
When I'm on a call using Whatsapp or Kakaotalk, the other party can hear their own voice (echo). I never hear any; it's perfect for me. When I switch to speakerphone and keep the volume low, then they DON'T get the echo. With earphones plugged in (iphone style earbuds), they still hear the echo.
Does this sound like a software issue?
I installed a mic app to record voice/sound and when I speak into it, it's fine. No echo, so the mics are operating properly.
Weird, and the gf is getting annoying.. sigh
Posting my fix for future reference. After some research and lots of software testing (tried 3 differen roms, Oreo and Pie), I believed it to be a "hardware" issue. On youtube, I saw a video that described a fix and I basically did that: https://www.youtube.com/watch?v=FkcxzmCPFWw
I took soft foam and covered the areas around the bottom microphone with it. Both underneath the plastic shield (boombox speaker) and above (just under the back panel). It has reduced the echo to 10-15% of the amount before, but not completely eliminated. I think I can live with that for now.
