[Q] Audible "pop" from speaker when sound is muted - Nook HD, HD+ Q&A, Help & Troubleshooting

Hello All,
I have the official CM 10.1.3 flashed to my Nook HD. Been running great for a few weeks - no issues. I only noticed this last night because it was the first time I used it in a completely silent room with the device muted. When playing a game that would otherwise produce a sound when tapped, I'm hearing a "click" or "pop" from the speaker. It's low, but it's definitely there. As if the sound system is turning on. After a short time, if I don't tap anything that would've produced a sound, I hear it again, presumably when the sound system turns off. This repeats as I play.
It's certainly not a big deal, but I was wondering if this is normal. With the sound turned on, at the lowest setting, I don't hear the "pop", just the normal sound that should be there. I also don't hear the sound system turn off, but it could be that I haven't tested it that much, or didn't notice it.
Anyone else experience this behavior? Thanks!

I thought I heard a pop and the device did a reboot after putting in an sdcard. Possibly static related? This is my first winter with a tablet.

[Q] Background noise while and after playing sound

I have very annoying problem. Everytime any sound is played there is background noise which stops 2-3 secs after sound ended. This noise is pretty silent while i don't use headphones, but then i use them on ~20% volume and i'm in a silent room i can hear this noise. Any way to stop this? I'm already tried to use another ROM but nothing helps.
+1. Just started a week or so ago, flashed a new ROM, still have the problem. It sounds like the speaker driver is turning the speaker on and off, it's a relatively loud pop or click before and after any sound.
I suspect (hope) it's a driver or setting issue, but so far I haven't been able to find a fix.

[Q] Speaker Hiss - Stock Captivate

Hey everyone!
I'm really excited, yesterday got a brand new Captivate in Canada. I guess I'm one of the first, the actual launch date is the 25th but not every Future Shop follows the rules.
Anyways, here's my problem. I've noticed that any time the phone makes a sound, the speaker will hiss for a second or two. As in while the sound as playing, and for a second or two afterwards. It's not incredibly loud, but it is noticeable. It sounds like white noise, but not as harsh.
I took it back to the Future Shop where I got it, and luckily there was a Samsung rep there. He had never heard of the problem. They said they would do a replacement of the phone, no problem, but I was just wondering if anyone had heard of this or knew of any solutions.
I haven't changed the phone in any way, and it's done it since day one (I guess that's not saying much, this is day two). Pushing on the speaker doesn't help, as suggested in the threads where people have had speaker problems. Anyone else having similar problems?
Thanks in advance.
I don't know that my experience applies to the speaker itself, but I noticed something similar last night when I had headphones plugged into my Cappy.
Whenever I would launch a program, play a sound, etc, I'd notice a very audible hiss/white noise. As this hadn't been an issue earlier, I figured it was something I changed. The first place I had looked was in the TV-out settings, and discovered that I left it enabled. After unchecking the box (Settings > Sound and Display -> TV out), the hiss was gone, or at least barely noticeable.
I find exactly the opposite... The hiss stops completely when headphones are plugged in. No hiss on the headphones or the speaker. TV out is off, as well. Thanks for the response though.

[Q] Rear speaker buzz

Last night went to play a game on my NC running phiremod 5.1. While playing I turned the volume off and brightness down due to son sleeping. I then noticed this buzzing sound coming from the rear speaker, it then stopped when the screen went to sleep. So I turned the brightness back up and it went away, for the most part just a very faint "shhhhh" sound if I put it to my ear. I thought it may be something with mine being rooted, so I checked my wife's stock NC and it does the same thing.
So has anyone noticed the static, buzzing, or hissing sound from the rear speaker? Is there a fix for this or just something the NC does?

I just started noticing this with mine as well the last couple of days. Screen on = buzz, screen off = no buzz. Not sure what it is, but it can not be normal as I know mine has not always done this.
I'm also running phiremod and I just checked, my nookcolor also buzzes when the screen is on. I think this may be a problem with CM7, after putting it on my phone (Acer Liquid E) I've noticed that the speaker buzzes, it never did that before...
IIRC, this is already a known problem over in the devel area. They are working on fixing it (and may have but I haven't checked lately.)
I believe this was fixed in CM7 Nightly 61 (10 days ago) and onwards, so there shouldn't be any more speaker buzz when the screen is turned off.
This results in drastically better battery life while the screen is off. Before Nightly 61, battery use was 1% per hour with the screen off. I believe it's now down to 1% every 10 hours or so.
(There is speaker buzz while the screen is turned on but shouldn't affect battery life.)
I JUST upgraded to Nightly 74 from 7.0.2 this very morning, so someone correct me if this is not accurate?
There is no buzz when screen is off, only when on. I did not realize that my speaker was even making any sounds before yesterday and I have been runing CM7 off emmc for awhile now.
I thought it was nightly 64, but that's also my understanding of it.

Strange External Speaker Static

Continuum 6 RC1, TalonDev kernel (whatever is baked into RC1.)
First off, every time I restart my phone it gives a couple of pops.
When playing sounds, a low level static also plays over the speaker, continues for a second after the sound ends, and then ends with a slight 'pop' sound.
It happens even when headphones are plugged in, and for awhile on Continuum 5.6 using the speaker phone in calls would cause my phone to reboot. TB is restoring apps at the moment, I'll post later whether or not I'm still having the reboot problem on 6 RC1.
What do ya'll think? Sound like a hardware problem?

CM9 Sound issues

I'm sure most of you will be aware with the horrible sound issue that plagued webos after the 3.0.3 update where the touchpad would cut all sound without notice if headphones were plugged in or out or if you just looked at the device funny..
On cm9 however, I'm experiencing an issue with the sound that is worse. Whilst watching youtube videos or doing any activity where a sound is played, the speaker often "pops" once in the way you can faintly hear speakers even there is no input, regardless of whether headphones are plugged in or not. From then, the speaker no longer plays any sound of any sort.
Does anybody have a fix for this? I just lose sound randomly and sometimes even a reboot doesnt fix it. I know that CM9 is 'fullofbugs' and that the audio libs are a mess/broken, but I would just like to know if this is a common issue with a known fix! Thanks!

I am experiencing this as well running AOKP M4b28 - it only happens (or as much as I've noticed) when the screen goes to sleep while I have music playing.
Glad I'm not the only one.

I have the issue when the screen is off and volume is >= 50% Never had any sound probs with WebOS that I noticed.
From what I've read, it has been addressed and is a know issue. You've got to remember that this wan't meant to be an Android tablet, there WILL be bugs. They might eventually get fixed but, I'm not one to complain, I've got ICS on a tab that was never supposed to have Android to begin with lol
