No sound for my phone even after rolling back to the EUI 5.6 - Coolpad Cool1 Questions & Answers

Long story. Basically I never got the speaker working from Rom to Rom, different patches, and so on. Then I decided to rolling back to stock. Tried both EUI 5.6 and 5.8. Still no speaker sound.
Anyone has experienced the same problem? Really need some inputs.
Many thanks!!

Microphone issue in software

The problem with me d802 is extremely weird. I was using my LG G2 all stock, when suddenly the microphone sensitivity became almost zero. I had to hold the phone extremely close to my mouth while talking for the other person to hear me. And, the mic worked good on loud speaker and with external microphone too. I guessed it was a bad mic. So i got it changed. But it still didn't work. Next thing I did was root it, and flash CM11 Snapshot M12. And to my surprise, the microphone works awesome now. I though some tweaking may have fixed it, so i went back to stock. And the problem came up again. I flashed CloudyG2 and the issue was there too. I flashed CM12.1 nightly and the issue was there too. I flashed CM12 snapshot M1 and finally, the issue was gone again. After spending an entire week in flashing ROMs and changing modems, i have reached this conclusion that the mic works only on KitKat modem, and only with CM11 or CM12 installed. I also tried Omni ROM which is kk based, it gave me the same issue. If any one could guide me a little on this, it would be of great help. Thanks!

Camera autofocus vibrating.

I am trying different ROMs which are based on LOS. I was on AOKP and no using RR ROM. Both roms had issue where the camera begins to vibrate while trying to autofocus. Has anyone else experience this?
Yes! It happens very frequently on LOS and rarely on stock ROM. I believe it's a driver issue since it happened on stock a couple of times.
It's the OIS motor. Not sure how much strain it is durability wise.
I happens around 80% of the time on LOS for me. I have to switch between front and back camera a couple of times to fix it.
I thought I was the only one, it happens to me on stock as well. I shake the phone to try to fix it and usually works.
Any software fixes available??

Audio problems with Nougat

Hi,
I recently updated my phone to Nougat 7.0 and have been having some problems.
1. When I am listening to music using Google Play Music and I lock or unlock my phone, the music sometimes skips for a moment. Not a big deal, but it's an annoyance.
2. This is the bigger problem - my loudspeaker sometimes doesn't work. I first noticed it yesterday because system sounds weren't playing, and also when I tried to play music through the loudspeaker, it was very quiet and tinny and barely audible. It seemed to fix itself once I toggled silent mode a few times. However, this morning, none of my alarms rang, it also didn't make any noise when calls / texts came in. Luckily the vibration managed to wake me up!
I'm pretty sure that it is a software problem as it started happening since upgrading to Nougat, and also I haven't dropped it or had it in water recently. I have not rooted my phone or anything, it is all stock. I've only had this phone for around 6 months. Wish I hadn't updated to Nougat now as Marshmallow was working perfectly! I have since rebooted the phone and it seems to be working fine for now...
Has anyone else had this problem? I have tried searching on xda and on Google and can't find anything. Perhaps I need to send this back for replacement?
First mistake: updated to nougat.
Second mistake: not rooted.
Try to revert back to mm and root to install some audio mods.
My S7 had the same problems with the loudspeaker sometimes it work for some hours without any problems but then the problem comes back. Samsung-Hotline told me the problem is new they didn't hear anything about that!
Factory-Reset
SIM-/SD-Card removed
notthing works for me.
I hope they will start the rollout of 7.1.2 without this problem
Odd. Are you guys on sd variants of the phone? I'm on exynos and had no issues with nougat.
Exynos

Nexus 6 speaker issue POSSIBLE fix

I had retired my Nexus 6 a while ago due to the speaker issue that's been plaguing these devices. I decided not to sell it as it would be an issue for the next user, so I instead kept it in case of an emergency.
Certain issues have lead me to recommission the device, so I decided I'd see what's new. So far it is clear that there was never a fix, and some people swear that pressing on the speakers fixes the problem (whether temporarily or permanently). I never believed this as the only thing that seemed to fix it (temporarily) when touching the speakers is tapping on the speakers, but that seems to be related to the device rotating (which has also been known to let the volume go back up) and something within the gyroscope (something that some have brought up as well). My Nexus 6 unlike many others has the bigger problem where the volume will go down regardless of battery percentage, and it was terrible as there was never an instance in which I could truly use the speakers.
Reading around I have seen other "solutions" emerge, but never anything concrete. On a YouTube video's comment sections I saw one person mention that Franco.Kernel fixes this, for me this did nothing. On another forum I read a guy who said his issue stopped using Lean Kernel, and that it may have something to do with mp_decision. Unfortunately for me, I like to stick to the latest version that was officially released (in this case 7.1.1) and Lean Kernel doesn't seem to have made it that far. I gave up on experimenting for the sake of the speakers at this point and settled on my favorite rom which is Dirty Unicorns, using the final 7.1.1 build (somebody was nice enough to provide links as I could not find it anywhere and their official page only has their Oreo based builds). Obviously the speaker issue persisted here. At this point I wanted to see if there was a Kernel with good features and battery life and came across a thread that mentioned BL4CKB1RD Kernel. I flashed that and was a happy camper as my phone runs cooler (no difference has been made to my 4 hour average screen on time) and ultimately lag free. Reading the maker of the kernel's current set up using the kernel, I decided to copy it a bit by limiting my maximum CPU frequency to 2.5GHz and using said governor profile. I came across the mp_decision setting and turned it on just out of curiosity (I have no clue what it does). Later on, I went to watch a YouTube video and before I could connect my headphones, the video was playing...with perfect sound. I thought I was going crazy, so I let it play for a bit longer. No volume drop. I picked up the phone, moved it around, rotated it, blasted the volume to the max and still not a single drop. For literally an hour I watched videos and absolutely no volume issues. I decided to undo all kernel changes and reboot to see what would happen. Still no volume changes. I also decided to lock the CPU and GPU maximum frequency to produce more heat, still nothing. I played Subway Surfers which was a guaranteed instant volume drop, nothing. Rebooted several times more, let the battery die, speakers are still perfect. Could this kernel have fixed my issue? Maybe. It is also worth noting that before flashing the kernel, I ran a command via terminal emulator (requires root) that I read about BEFORE flashing the custom kernel, and I never rebooted my Nexus 6. The command can be found here (there was another thread that also included it but also linked to this thread):
https://forum.xda-developers.com/nexus-6/devs-only/speaker-amplifiers-nxp-tfa9890-research-t3236518
Anyone with the speaker issue should perhaps start by this command, reboot and see what happens. If not, try using BL4CKB1RD kernel and see what happens? If still nothing, try toggling mp_decision on and then test.

I just ordered a nexus 6, is this issue common? Does it affect stock rom or custom roms? I have a Moto X Pure at the moment, Nexus 6's brother, it has a similar issue where the sound cuts out when the phone is switched from portrait to landscape and vice versa but only affects custom roms. Its doesnt lower the volume though

For most the issue occurs at low battery, and the drop isn't major. I've seen some videos of people with this specific problem and I laugh because they don't know have it as bad as us with the major drops regardless of battery life. So pretty much the low battery volume issue is more common than the worse one, and you could say it is a common issue.
We had a white one that had absolutely no issues except a faster battery drain (perhaps because the speakers worked?!).

My Nexus 6 arrives tomorrow and I'll be flashing it right away. If I have a volume issue I'll definitely keep your kernel in mind. Thank you

Dumb question does your kernel already have these included?

Yes.
For what it is worth, mp-decision is Qualcomm's own hotplug: it turns the processor cores on and off depending on need. I guess it may use other tricks as well, to optimize power / performance.
No obvious reason that it should affect the speakers, but you never know.
Does this thread address the issue with SEVERAL 8.1 ROMs I've used, in which the speaker phone does not function during calls... and during calls alone. I can play media just fine... IMMEDIATELY after the speaker not working on the calls. I CAN however plug a headset in and communicate normally . Just desperately seeking an answer or I guess I'll go back to 7.1.2
So now nexus 6 is running pie roms nearly perfect . Unfortunately this sound problem persists… it is truely fristrating
So is there any kernel that can fix it in pie roms? Thanks
I have been using my nexus 6 for a couple of years now and had the speaker issue about a year ago and went into recovery and wiped cashe and the. Did a factory reset. Did an OTA update and everything was fixed.
Last weekend I finally flashed TWRP and then rooted with Magisk. Went to install myself5's Bata version of Carbon room running pie... Not sure what happened but had error code 7 and bricked the phone. Had to wipe it out and went though Google to get an old OTA and reflashed and thankfully got my phone back. Tried the process 3 other times and got the same result. Each time no speaker issue.
The last time I tried it I left it alone and didn't even put TWRP on it but now the speaker problem comes and goes.
5 min agot I was playing YouTube music with no issues, made a phone call, then back to YouTube and now the bottom speaker quit and the top speaker is very quiet.
Any ideas on what could have cause my issues and can someone direct me to where Ii can find more information or what I'm doing wrong on on flashing new roms?
Currently running Android 7.1.1 build NGI77B

I've honestly encountered this problem a couple times but rebooting/flashing fixed the problems. Worst case scenario go back latest Google ROM with WUG's software, then you can install TWRP, then a custom ROM like Nitrogen ROM.
Sent from my shamu using XDA Labs
I know nothing about what anyone is saying, but I would like to add that using Viper4Android, and using "eXtra loud" at "Moderate" with the max gain at 4x and the max output at 0db completely gets rid of the low volume problem. Viper works system wide so it fixes it for Netflix, etc
Hope this helps guys

Sorry for the late reply, I had to put the Nexus 6 on hold due to another issue with it. I tried your kernel with the latest official version of Dirty Unicorns, but unfortunately it does not boot. It will boot fine without flashing the kernel.

Having this same issue using the NitrogenOS Pie rom. Updated from 7.1.1 (didn't have this issue with 7.1.1).
Is it better with the Oreo 8.1?

No . I can confirm that all oreo roms got the same bug .
For me am using android x unofficial pie rom with popcorn kernel. This combination seems to fix this bug !
Try them or even try the kernel with nitrogen os rom .It may work..

Unfortunately no. Mine WAS working perfectly. The charge port broke after about two weeks after I made this thread (my luck), and after having it repaired, the problem seems to have gotten worse. For one, it no longer works in the configuration I mentioned in this thread (mind you, I did not reset it or anything). It also now varies from rom to rom, with the bigger issue now being that the top speaker ceases to function on certain roms, including the way I had it. Now, it drops volume for everything, and most of the time the top speaker will be weaker for the slight moments both decide to work.
New problem
Hi Crossvxm. I have had a Nexus 6 for two years. When I wiped it to sell it, the audio problem started. I had PureNexus.
I did what you suggested. I turned on mpdecision with BlackBird kernel and kernel auditor. I installed su terminal, to execute these commands with root access:
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0034/force_calib
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0035/force_calib
And the full volume audio came back! Videos, youtube, all working again! But, the audio in calls worked no more. So, after that, I wiped all, installed PureNexus 7.1, Nitrogen 8.1, stock 7.1... I tried everything, but the audio in calls never returned. When I reinstalled all these roms, the low volume problem appeared again, but the audio in calls never came back. Even WhatsApp calls have no audio. The microphone still works, because the other person indeed can hear you.
Do you have an idea about how can I solve it? At least to leave it usable as phone. Thank you very much for sharing your knowledge and time.

This sounds like what happened to me recently. The configuration I mentioned in the very first post worked perfectly. After taking it to have the charge port fixed, the top speaker stopped working, and you could not hear the top speaker at all during calls. I thought the store broke it, but after giving up using it for some time, I realized that it would randomly try to output sound from the top speaker. After starting all over (flashing back to stock and flashing my same configuration again), the problem changed to where the top speaker was very low in sound when both speakers felt like working. I flashed the latest Dirty Unicorns based on 8.1 along with Popcorn Kernel by athulele but unfortunately it did not boot (as mentioned in his thread, the kernel is Lineage based).
I gave up on the Nexus for a few more days. When I decided to give it another go, I flashed the latest LineageOS (along with root for it via their own separate flashable zip), flashed Popcorn Kernel, installed Kernel Adiutor from Google Play (yes, it's spelled that way), installed the Terminal Emulator for Android and ran the command as well as checking the kernel settings to ensure MP Decision was on, capping the max frequency to 2.4Ghz (feels much less hot) and making sure everything was set to "set on boot". Unfortunately it did not work. The only way I got it to work again was to give up again, flash back to stock and flash Lineage and Popcorn Kernel exactly as I explained in this second paragraph.
So why did it work this time around? Everything was done the same, what could possibly make it work? I have a theory. When it was taken to the shop for repair, the battery died since it was already at 20%. As you can see I mentioned a few times "I gave up" on it, meaning I stopped bothering to fix it, and eventually it would run out of battery mainly from wifi and notifications. Every time it was dead, it was usually dead for at least 24 hours. Each time around, the issue would change. I don't know what it has to do with anything, but I do believe it plays a key role. Try letting your battery die, charge it back up to 100% and then try the process from either paragraph two or from my original post. After it began working again, I abused the heck out of the speakers, rebooted the phone, tried calls, etc. all without letting the battery die and it has not stopped working. I recently sold it as is and was contacted by the person who purchased it who was confused as he did not experience any sound drops either. He was originally buying it to replace the screen on his but decided to stick with mine since it was working perfectly so far.

External Speaker useless after 8.1 OTA update (impossibly quiet)

Not, rooted, located in US.
Before I did the OTA update to 8.1 last night, my external speaker worked fine, both for speakerphone calls, and media playback.
During my first use of 8.1 today, the external speaker is now so quiet (on full volume) that it's useless in all but the quietest rooms.
Calls on speakerphone are barely louder than if I just shut the speaker off. Watching Youtube on full blast is barely discernible in an average noise environment, and forget listening to music outside or in the car.
Anyone else experiencing this?
Same problem here
It's a official software bug. Most of the people who updated Oreo got this issue. If you want to use your phone use any other custom ROM available here. Otherwise need to downgrade to Nougat. If you can wait for another update from Moto to rectify this bug means bare with this volume issue untill Moto releases new update to fix this.

Thanks for the feedback. Unfortunately I doubt Moto will ever release a fix for this.
I never bothered rooting this phone, I guess I am going to find out if its even possible, now that it has Oreo on it.

Rooting stock Oreo is even easier compared to Nougat, because you don't need a custom kernel anymore. Still I would advise to use the new Loony Kernel or ElementalX for being able to use different RGB values if your device has screen retention problems.
Other observations from this OS "upgrade:"
My phone now struggles to stream Youtube to Chromecast... video/sound sometimes is choppy... previously no issues at all.
Sometimes the phone randomly decides Wifi wont work. Can flip the switch to the on position, but it still says "Wifi is off." Only recourse is to restart the phone.
Overall very disappointed. Can't wait until I get a chance to root and ditch this OTA update.
