Tmobile S4 CM 12 no call audio - T-Mobile Samsung Galaxy S 4

Hello all. I admit to being a noob in terms of installing custom ROM's but have installed CM 12 to my m919 (Tmobile) S4 which works well - except for no audio during calls...
I have roamed the internet and tried various things like installing Sound About, as well as disabling the 'OK Google' feature, with no success. I have Vonage extensions app on my phone and can make calls fine with that - that is of course, voip, but does establish mic and earpiece work ok.
Is this something to do with the modem? I see mention of installing an updated baseband though I have no idea. I also read somewhere about someone flashing stock lollipop first, then CM 12 to fix it? All a bit bewildering to me at present.
Wondered if anyone had any info. Thanks in advance

[Q] EVO 4G - Bluetooth Killing WiFi!? Anyone else having this issue?

I have one of the 1st White EVO's from Sprint and ever since It's been Rooted and running various ROMs I've had this issue where Every time I get a call and use my BT-Headset, it kills my WiFi connection. If I use my Speaker phone option the WiFi stays on and works just fine. Roms I've tried and this issue persist: AVA-Froyo, Fresh Rom, Freak-E Froyo, and currently running MIUI. All have been the latest versions. I've update my Radios with the current Radio "Combo Zip" and still have this issue. I've tried various headsets from the $9.99 Cheapo's to my $99.99 Plantronics Voyager Pro+ and still have this issue. If there is something I'm missing or anyone else has had this issue with the EVO, please help or point me in the right direction. What's the point of having a phone that's supposed to multi task with Voice and Data if the built-in features are killing each other?
*!Update!*
======
I am now running the latest [EVO NonSense v3.4] ROM and it's all good. I've made several calls and my WiFi and 4G are working as they should. Plus my Bluetooth transmission is a 100 times clearer as well. I'm no expert, but my only conclusion is that it could be the Kernels.
Does anyone know if the [2.6.32.15-gof673ed [email protected] #10] will work with the above mentioned ROMs, particularly the latest MIUI?
Thanks in advance for any help and quick replies.
I posted about this a little while back, have the same problem
On call through my voyager pro wifi is intermittent. I don't think it kills it, only makes it so slow that almost everything times out. Almost randomly it goes in and out. Same with 4g as well
Edit: Not rooted

[Q] Garbled phone quality after flashing

I'm a first-time poster here but I've been using XDA for years to root and flash phones. My first android phone was the EVO 4G and I've had about 5 since then, all of them rooted and flashed multiple times with no issues to date... until now!
My wife has an older T-Mobile Galaxy S2 (T989). She was having problems with the keyboard hanging and text messages lagging so rather then wipe it and restore the stock ROM I figured I might as well update it.
I used the latest release of CWM and rooted the phone with SU.
Then I flashed a new radio ( SGH-T989D_TLMC4_radio ).
Then I flashed Paranoid Android 4.0 beta 6.
Then I flashed mini gapps.
Everything on the phone seemed to be working great but then today at work she tried making phone calls.
The phone is able to dial and make calls and pickup and receive calls but the actual call quality is terrible. The voices are all broken up and have high pitched digital noise mixed in with the voice of the other caller.
Should I experiment with flashing different radios? I did a search and couldn't find much but I wasn't sure how to word the problem so it might be a common issue that I'm not aware of. Thanks!

I think the radio you named above is for the Telus version of the phone (not T Mobile). Here is a link to the radio thread:

No sound when making, or receiving calls, same for those being called...

Hello fellow galaxy users, I have this problem on my T-mobile Samsung galaxy s4 and it is when I make a call, I cant hear anybody on the like or the dial tone or anything, and when the other picks up my call they can't hear anything either. Also if I pick up a call I still cannot hear anything. It is just plain silence. NOW HERE IS THE WEIRD PART! If I turn on wifi calling, I can call and receive calls with out any problems, if I use skype I can hear from the speaker and everything. So my mic is working, my speakers are working, everything seems to be functioning... Till I make a call using data... My guess is its a T-mobile network issue? I called T-mobile and they didn't know what was wrong... I looked around google and many people are having the same problem with no solution... If anyone has any ideas or any solution and would like more info on this problem, please let me know!
Have a nice day !
im having the same exact problem! i have seen some fixes that people have posted with similar issue, leading them to believe its something with their bluetooth/ok google/s voice being involved. ive tried some of the fixes that have been posted, but no luck on fixing the issue on my end. but just like you if i go on wifi and make a call i have no issues what so ever! the sound also works just fine if i connect to a bluetooth device.
Are both of you on the full NH7 firmware?
Mismatched bootloader?
Pp.
fully stock rom, not rooted. OS 4.4.4, yes nh7
i will add that this is my first galaxy, that i haven't rooted or changed the rom on. i have yet to have a reason to root or change the rom on this phone, but if i have to, to get this fixed? i have no problem rooting and changing the rom.
also i have noticed that i drop LTE to 4g when ever i try to make a call. the wife has the same phone and is on tmobile as well but she has not had this issue.
Ok, since you are stone stock this could be a update issue, just out curiosity I would try a factory reset (hard reset ) it may solve the issue . If not I would go with stock rooted like ShinySide's rom not full custom until issue is solved.
Pp.
ive done a hard reset and the problem is still there. i guess ill go the ShinySide's rom way, until i get my s5 or wait for the rumored s6.
This by ShinySide will give you an option to flash a stock firmware if you choose to be stock again. Follow instructions using Odin.

[Q] [Q&A] Sound issues on custom ROMs

So as the title says i've Unlocked, installed CWM and Rooted my 816 which is Dual Sim.
I then installed the unofficial CM12 from Grarak,
while mostly the rom was fine for me, i just couldn't get over how it sounded, especially at max volume.
There was a lot of distortion and extra sounds going on. I tried the Official CM11 , but had the same issue.
I'm wondering if there's any third party app or flashable software to make it sound like it does on stock?
EDIT: I'm also experiencing network issues, such as Network search coming up with an Error and finding 0 networks. It really bothers me since my carrier supports 2 networks, 1 free and the second is charged,
Automatic just seems to switch to the charged one a lot.
Thanks for your answers

Without HTC's audio drivers that are built into sense ROM's the auido will be very sub par.
As far as your network issue's I have no clue.

Thanks for your reply, i was thinking along those lines, but thought maybe there was a workaround this issue. Well it's not that bad as long as i keep the volume a few steps below maximum.
I just hope we get some official support for lollipop, because i freaking love it so far.
You should try flashing audio mods such as xLoud or a mod that has many other audio aspects.

[Q] CM 12.1 Dialer Will Not Hang Up Calls

I installed CM12.1 on my d851 and I cannot disconnect calls. I tap the red button to hang up and the phone app hangs on "hanging up" but does not actually disconnect. Has anyone successfully gotten the CM12.1 dialer to work on the T-Mobile G3?
I have the same issue when I install other custom roms based on CM.
Any help would be appreciated.
Re: dialer will not hang up
Hi,
Did you ever work this out as I'm also having issues with CM
12.1 not hanging up on galaxy s3 Verizon.
Thanks
David
Having the same issue as well 2 i605 on cm 12.1 just switched from rip off VZW to T-Mobile and this bug started. Phones worked fine on Verizon... Can someone please get this fixed?
i don't have a solution for cm12.1 but maybe if i share the (quick) solution that was used in cm11, some smart person here can figure it out--hopefully, once and for all.
in cm11, all you had to do was add a single character to a field in build.prop, which was something like:
ro.telephony.ril.v3=newDriverCall
to get:
ro.telephony.ril.v3=newDriverCallU
in cm12.1, the rom is presumably already shipped with the correct settings:
ro.telephony.ril.config=newDriverCallU,newDialCode
but does not work (for those of us using sph-720, especially). someone who understands android can maybe port the old (and simple) fix to the new one(?)
also, i appreciate the work guys do to get us these builds, but it'd be nice not to reintroduce big issues like these as it basically forces a potential user not use the rom, which then wastes the hard work of porting it to a particular device in the first place. i can live without data since i use wifi heavily, but not being able to receive calls is a no-no.
