Loss of "speaker" output - ONE Q&A, Help & Troubleshooting

Everybody,
So I've had my OPO for a while, but I've noticed a few times that after being booted for a period of time (several days to a week), the speaker output seems to go silent. This means that when I use the volume control, it no longer sounds as I move it higher or lower, phone ringing is mute, etc. If I plug in a headset, I can hear everything fine there. Upon a reboot, it goes back to normal however.
Has anybody else noticed this behavior?
I am on CM 11.0-XNPH38R, although I believe I observed this at least once on the previous build. It "feels" like it is getting stuck in headphone output mode.
Any help or supporting observations if this is a general problem, or something specific to my unit would be helpful. Thanks!

[Q] Low speaker volume

I'm currently running stock, un-rooted 3.18 from AT&T.
My speakers, both on the back and the earpiece, have extremely low volume. Even at max volume I have difficulty hearing phone calls anywhere that is not very quiet. Also, my ringtone and notifications are very quiet. Again, they're so quiet I generally don't hear them if I'm not in a moderately quiet setting with the phone face down nearby.
I don't seem to recall this being the case when I first got the phone. I also tried a couple different ROMs recently, but none of them seemed to help so I just went back to stock.
On a potentially related note, whenever I'm playing music and get a notification it gets played very softly in the background, and is often inaudible. If I get a call it pauses the music, though.
Any help with either or both of these issues would be greately appreciated.

[Q] Audio characteristics changed; can't revert

Hi folks. I have a 16GB US GSM Moto G, and yesterday, the character of my device's external speaker changed.
Formerly, to get a good average sound level in apps, the volume needed to be near the high end, I'd say about 60-80% of max. Now, that same volume level corresponds to about 20-40% on the slider. At the same time, I started to get weird sound artefacts in one app (Tiny Death Star). I hear a light popping sound in the speaker about once per second, and every couple of seconds the sound stutters. Not terrible, but enough to be distracting. It doesn't affect all apps, but I haven't tested extensively to see if it's the only app affected.
There are a couple of variables:
1. Yesterday I installed the KitKat OTA update. I'm about 80% sure that the issue didn't start immediately after that, but I can't be positive.
2. I played with a couple of music player apps: WinAmp and PowerAmp. In the latter, I did mess around with some EQ/volume/balance settings, but I left everything where I found it. Once I noticed the new issue, I uninstalled both and rebooted the device, but the problem persists.
I also noticed the "Audio Effects" setting in the Sound settings. Tried turning that off, but it didn't change anything. I also tried wiping the cache partition; no change.
Anyone have any idea what may have caused this (and more importantly, how to fix it)? I could live with the volume range change, but not so much the stutter/pop.

[Q] Music Volume Lowers On It's Own

This has happened to me a multitude of times while working out. I have headphones plugged in and about 20-25 minutes into my workout, the music I'm listening to (either Google Music or Spotify) will lower all the way to mute on it's own for no reason. I'll try and increase the volume wither by the rocker or on the screen, but it still lowers all the way down on it's own. After a while, I can increase it a bit, but then a minute back into it, it'll slowly start to lower again on it's own. I've turned off the safe mode so that you can't listen too loud...but that doesn't do anything. I thought it might have something to do with the orientation of the screen, so I turned that off as well. At times, it'll be ok and then one random day, it's like a ghost wants to mess around with me.
Just to add a note, this all started after I've rooted my phone and I've gone through 3 different ROMs (Cyanogenmod 11, SlimRom, and Purity Rom). Is this an issue with it being rooted? When I was on stock this wasn't an issue. Anyone else having this problem?

Speaker volume goes quiet and loud

I'm hoping someone can help me troubleshoot volume issues I'm having on my Nexus 5 running the latest build of LineageOS (24 October at this time). Tell me what to look for in the logs or other troubleshooting steps I can take before taking it in to get the speakers replaced.
I've had this phone since April with no issue. I got it as a refurb off Newegg. Since the beginning of October or so, the speaker volume has been inconsistent. Up until this issue, the sound coming out of the speaker was consistently good: it was loud on high volume and quiet on low volume.
The speaker sound recently started randomly (in that I can't seem to find a pattern), becoming very quiet, even with all the volume sliders turned up to maximum. I'd estimate that the speaker output during these periods at full volume on the phone is about the same as when it's behaving normally and I have the slider down to under 25%. The volume will restore itself, be fine for a while (anywhere from a couple minutes to hours), and then go quiet suddenly, again from anywhere from a couple minutes to hours.
Some notes:
I've ruled out the speaker switching from the bottom speakers to the speaker at the top of the phone where your ear goes when taking a call. The bottom speakers go quiet.
The volume is quiet for the ringer, alarm, media and notifications. Fiddling with these sliders does nothing.
I've wiped the caches from TWRP, rebooting, restarting, powering off and so on. No consistent effects.
Headphones seem unaffected and the volume is normal.
I'm aware that there was a volume issue with Nexus 5s due to a security release back in 2013 or so. I understand that bug was fixed in subsequent releases and, presumably, is in LineageOS. Therefore, I doubt this is related to that.
I've picked through the logs and one thing I'm noticing is that there are ThermalEngine alarms being thrown. is it theoretically possible that, to reduce heat, Android is cutting the volume level?
I'd like to avoid factory resetting the phone, but I can once we eliminate other issues.
I'm reluctant to say that it's a hardware issue because I don't get any distortion from the speakers and, when the speakers go quiet, I don't notice any sound quality degradation. Further, the speakers haven't been getting quieter or louder. However, if all else fails, I'll have to take the phone in to get the speakers replaced.
I'm grateful for any help the community can provide.
With thanks,

One plus 8 unknown issue

I am using a Chinese version that was flashed with Oxygen OS. Currently running with Android. Had no issues for the past 5 months. Suddenly this issue (while only with earphones plugged in) encountered and is occurring frequently.
Issue:
1> When plugged in an earphone and watching videos, the vide gets automatically paused and played and the volume gets decreased. When increased the volume again the volume automatically decreases.
2> While Listening to music or playing games also the volume suddenly gets decreased and when increased the volume the volume again gets decreased.
3> While on call, the caller doesn't hear what we speak at times and I also cannot hear the caller speaks at times.
Thinking the issue was with the earphones, tried changing to 4 new earphones but the issue is still the same. Tried resetting the device, still the issue is the same.
Someone please help me sort this out or let me know what the issue is?

If this is just an issue with wired earphones and not Bluetooth earphones I would suspect that there is a problem with the usb-port or the usb-c-to-3mm jack if you use one. Have a close look the se if there is some dirt inside the port. Try a vacuum cleaner to get dust or paticles out. Or replace the usb-c-to-3mm jack if you use one. Not all of these work with all phones. They are not all the same.
