[Q] Distorted sound at less than full volume

I've had my DHD since they came out last November and I've had no real issues with it in all that time. However, I've now got a hugely annoying issue with sound where all sound, ringtones, music etc, comes through distorted at max volume where before it was clear. The obvious suggestion is to turn the volume down but even two steps down from max. volume it still happens depending on the sound coming from the speaker. I don't know how else to describe it except perhaps tearing and that doesn't sound very accurate to what is happening.
I don't remember when this first started happening but I'm pretty sure it was a few months ago and I was using a Sense based ROM at the time. The issue got so bad that instead of playing distorted sound in Sense it would just cut out and all sound would stop for what seemed like two or three minutes. Switching to CM7 has prevented it cutting out but the distortion is still there so I don't think it's related to a specific ROM unless it's a volume boost that was done over all ROM builds. As anyone who owns a DHD will know the audio has always been a little on the quiet sound but the level I have the volume at now is below what I'm comfortable with.
Can anyone offer a suggestion on how to fix this audio issue? It's almost to the point now where I'm thinking of going back to stock and sending it in for repairs. Don't make me do that.. you know it's not a fun process.

I'm only replying to this in case anyone has similar issues so they can see my resolution. Unfortunately it's gotten worse, to the point that I lost all sound on all ROMs bar a few squeaks from the speaker. The in-call speaker worked fine and I could make calls with no issue but no notifications, alerts, alarms etc would sound on the external speaker.
I flashed back to stock Gingerbread and I've sent my phone off to HTC, via T-Mobile UK, to be repaired. I'm also hoping they fix the misaligned camera issue too. I'm a little worried because despite trying I could not get S-ON back before I took it in but it's using stock bootloader and an HTC RUU ROM. Anyway, I'm basically saying that it's a bad sign and will have to go in for repairs. Hopefully this will save anyone from wondering in the future if they get the same sort of issue.

I'm having the same problem.. I think.. if you are talking about the speaker that you make the phonecalls with.. not the "external" speaker.. that works fine..
it has a crackling sound with mine.

Sounds like the external speaker is busted. You already send it to repair, probably that's the only solutions.

Microfone issue

Hello,
have a problem with my HTC 10 when I make standard call there is no any problems, but when I switch call to loudspeaker people tell that they can't hear me, phone usually lie on the desk during this calls.
Is this hardware issue, or software? I use Viper ROM. This phone have two microphones right, which one is used with loud speaker call?

Hello, the same speaker like without Loudspeakermode. Try another ROM at first Stockrom, shouldn't help this i recommend to contact your seller.

speaker no matter if phone is at the ear or call is in "speaker" mode works without any problem,
my problem is with microphone but only on "speaker" mode because then other side can't hear me.

to resolve it, I've bored out the microphone hole on the bottom of the case enough to make sure the mic is fully exposed and that appears to have done the trick.

Noise cancellation not working properly

Hi friends,
Can you guys confirm that noise cancellation is inactive in OOS 3.2.7 stock, unrooted, locked or do I have an isolated issue?
Tinkering around on my phone OP3 in the engineering mode, I did an "echo test". When "Primary mic" is selected, the speaker echoes the taps or my light blows into the respective mic but no such thing happens when I try that with the secondary mic.
Is this a bug in engineering mode for the oneplus 3?
if yes, how can I test for noise cancellation else where?
if no, can I ask for replacement?
Thanks

I dont think its a hardware issue, most probably the mic is just fine. That is the reason why phones usually have dual, sometimes more, microphones to help with noise detection and cancellation, but Op3 still has problem with this mic recordings and noise cancellation. I think this is either due to coding and programming issue with audio threshold of recording or dismissing noise, or due to the fact that microphones do not coordinate together properly which may be due to poor placement of the mic on the back of the phone that can get blocked often. Im interested to see if someone solved this problem, since i have quite a lot of trouble with it, when i use speakerphone in whatsapp call many times i talk but the phone doesnt register it, or it registers it really really low volume. Im not having the same issue when i talk on the normal audio call mode.

Yes, people are saying that noise cancellation might not be working properly.
If that's the case, I'll just want to make sure my hardware is not at fault here since I can't hear anything from the secondary mic.
Can you please try the above in your phone's engineering mode to see if it works for you or not.
Thank you.

Nexus 5X Microphone

So here is the problem. I have tried talking to Google Support and also LG Support. Not under warranty anymore. I have heard several different people mention problems with their mics in calls, be it incoming or outgoing. I have done several things to try to fix this problem; flashing stock firmware and upgrading thru OTA's, clearing cache, rebooting every day, flashing custom roms, modifying the build.prop, opening the device and checking for physical damage. To my knowledge this phone has 3 microphones that are used for actual speaking and background noise reduction. When I opened the device everything looked ok on what I assumed were the mics (the tiny square bits soldered to the logic board at the top and the bottom). I assume these were just going bad and finally gave out on me. Has anyone had any experience getting these fixed or repaired? Is there any software based approach I can look into? I am really tired of using my speakerphone in every call. I assume I am not the only person with this problem.
If anyone can shed some light on this or help in anyway I would appreciate it
Thanks!

I would start by describing the mic issue you are experiencing during voice calls.
Haven't had any myself.

No one can hear me using the microphone, as soon as I switch to speakerphone the other party is able to hear me.

I've read mics can stop functioning if you try and clean the phone with compressed air. As far as fixing or replacing a mic I am unable to provide assistance.

Well rats. Hopefully someone can shed some light on getting this fixed. I do have some soldering experience but I don't even know how this translates via the logic board. Anyone that has more information the help would be awesome. Thank you for your time though previous posters.

I have this problem as well, but also all media volume can't be heard through the speakers. I've personally cleaned and replaced the unit and nothing works, I just have to choose speaker and start talking, else use a headset or a bluetooth mic

Same problem, no solution yet.
Think that is a software/driver/app combination bug.
When Iam in call hardly can anyone​ hear me, if I cover top mic - then im heard again (proof that bottom mic is working).
Top mic is used to cancel background noise, phone interpret your voice as background noise and volume it down. That way nobody can hear you.
When I cover top mic - no background noise detected and my voice is heard again.
Question is why top mic detect legit voice as background noise?

Same problem here. Can't use microphone normally on any sort of voice call. I have to change to speaker for people to be able to hear me. I'm not sure if I still have warranty so if it's a software problem I might be able to fix it by myself.

Pixel XL - No sound from speakers

Alright guys, I've got a problem I haven't quite dealt with before:
I've got no sound coming from my "external" phone speakers. The in-ear speaker works fine, and so does the mic. That means I can take phone calls just fine. Listening to Whatsapp voice messages is a challenge because Whatsapp uses the speakers which means the message plays with no sound, that is until I hold the phone to my face and the prox switch tells the app to play through the ear speaker. No YouTube videos or Snapchat sounds.
I looked around the forums and such but didn't find anything. I've checked all the system settings I know to check, but nothing I can find is "muting" the sound. My apps list is fairly standard. Stock rom and kernel, unlocked since day 1 but without even a recovery installed. Basically a factory phone.
What are you guys thinking? I'm happy to try basically anything. Even thinking of slapping a ROM into this beast to see what happens, although I doubt there's too much development going on for a 2yo phone...
Cheers!

Update:
I've got intermittent sound. I haven't opened the phone and have no reason to think water ingress could be the problem, but I can't think of a reason that the speakers would work intermittently. Sounds more like a hardware problem than a software problem to me. Anyone else?

It also happened to me except I didn't have any sound coming from both speaker and the earpiece. Not sure what happened though.

Well it only has one speaker. As for the others most likely hardware related.

Weirdly, I'm stuck in unreliable-sound limbo. I get sound most of the time, but speaker sound disappears occasionally with no predictability that I've found. Interestingly, If I mash or smack the bottom of the phone phone screen by the speakers, sometimes sound will come back on briefly or entirely. Weird, huh? Not sure what could be causing a connection problem. Maybe I'll open up the phone eventually and find out.
