Hey All -
I ran a quick search and didn't find this problem. I wanted to document it for posterity.
My phone makes a buzzing sound. I've seen it in every ROM I've tried so far (seems to be a hardware problem).
The sound is faint, is unaffected by media volume, and goes away when wifi is turned off. The phone appears to shut off the sound hardware when sound hasn't been played for a while in order to save battery. This makes the buzzing stop. But if a notification comes in, or there is a quiet part of a song, you can totally hear it.
It exists regardless of the ROM I have installed.
The sound is like what you'd hear in an older computer with something called crosstalk. Back in the day, (and to an extent still), various components in the hardware would generate EMI and would affect the sound quality in sound cards. For example, I had an Adlib card that would buzz a little every time the hard drive would read/write to disk.
This sounds just like that.
Anyway... just vote in the poll/comment if you're having this problem. Please post to the thread if you have a solution. I'm not expecting much though. I'm pretty sure I'd basically need a new phone for this to go away.
I get a very slight buzzing in my phones, completely unaffected by wifi. Only happens with my CX300 in-ears, any open earphones i havn't heard any noticable buzzing (though have no tried any type of headphones yet). Using Voodoo sound, lowering the amplifier dB gain and putting the media volume up reduces it a touch.
I grabbed a pair of iphone earphones and the nexus s earphones to test it with some more types, no noticeable buzzing. Also, both their sound quality is appalling in comparison to cheap sennheisers.
Yeah, that's different than me. It sounds like your CX300s might be dying.
I've got some Klipsch S4i ear buds and Bose QC3s that both have the same problem. Its loud and clear enough though that I'm sure I could hear it with cheaper headphones.
I can turn the volume all the way to zero and still hear it. When I turn it up, it doesn't make it louder though, which is "nice".
I've been all over the voodoo sound settings and nothing helps.
That's a shame, your phone probably suffers a noticeable case of leakage between the components. Could this possibly be classified as a defect and be fixed/replaced under warranty?
Also, my CX300s have no hiss on a higher quality dac and it was noticeably louder on my old nokia. I guess they're just more sensitive, they are only 16 ohm after all. No drama for me
It might qualify as a defect. I'd have to bug Samsung I guess. I could see Samsung just telling me to deal with it. It doesn't make a lot of business sense to replace a $500 phone because the headphones hiss when wifi is enabled.
It would sure make me a lot happier about buying Samsung stuff in the future though.
That's really weird about your headphones. Unless the audio quality on the CX300s is far superior over the iphone/nexus s ones, I would expect them all to behave the same way. Even then, it would be very subtle. Maybe the Nexus S doesn't ground the headphone jack very well for your headphones?
You could give them a call/email and see how it works out, but you'll probably be left without a phone for a few weeks if you send it so probably not worth it for you either.
Definitely far superior in comparison, but not nearly superior earphones Possibly a grounding issue, could even be just an unlucky set of Sennheisers that i got and have always been like this. They are out and about anyway, take a good beating and have been rock solid. Hopefully soon i'll be getting a decent pair of headphones for home use, funds allowing.
My laptop does the same thing, I'm thinking it is just interference with the headphones and your phone. might also be a lose wire or something in the phone or headphones :/
I know that this is old tread, but I had the same problem and solution might help someone.
In my case, the source of the buzz was charger (poor power supply filtering in cheap switching sources). I bought some cheap car charger/dock, and whenever I plugged my phone into it I would get lots of buzzing noise. Of course, I used it every time when in car, so I did not notice correlation for a while.
Using better charger solved my problem.
If by any chance you are charging your phone while you listening to music and getting lots of buzz, try disconnecting power cable to phone and see if there is noticeable difference. If there is, you found your problem.
Thanks for letting us know grejigl. Although not the source of my particular (non) issue, i can see it helping out someone else down the road.
I'm running on battery power when it happens to me. I'm pretty sure its caused by something related to WiFi because as soon as I shut WiFi off, the buzzing is gone.
Hi All
I am on my second handset, as the first one had a huge gap between the screen and the frame which held lots of debris so exchanged it.
I didn't make that many calls with the original handset before i exchanged it, so did not have a chance to use the speakerphone for a call. However, today I made a call on speaker and noticed that the volume is really low until you get to full on the scale and then it suddenly jumps up loudly and sounds like it has been enhanced? In call volume through the earpiece isn't exactly stunning either, have to have the volume either on full on one below.
I tried playing music through the speakers and it sounds absolutely perfect, equally as loud as the first handset.
I'm considering exchanging again, as I definitely think that the first handset had much better call volume (can't be 100% sure though), but I just wanted to check here to see if others find the call volume not so great?
I noticed that when I'm sitting in a completely quiet room, when I play a video and set the volume to 1 bar, the sound is so bad you can hear literally only buzzing and other wierd noises. It's absolutely fine at higher volume levels, I guess the noises just don't get louder. And I'm wondering, because I have this phone for like four months, and I'm not sure if this got worse than it was at the beginning. May it be due to cleaning the dust with compressed air? Should I remove the cover and check if everything is ok?
Also, it can be heard better if you're holding the phone right by your ear, please check if it's the same for you.
It's really noticeable when listening to people talking, hard to notice when listeting to music.
I've noticed that listening to any music or certain audio frequencies at 75% or higher external speaker volume become very distorted, like it's pushing the speaker past it's limits. I've tested this with another friend's S6 and his is the same way. Easiest way to tell is raising the ringer volume and hearing a distinct high pitch with the volume adjust sound. Dunno how else to describe it.
Disregard this post. Because of the junk speaker, horrible LTE and wifi reception, and terrible battery life this phone went back.
The issue I am having are with my family who constantly put their phones on the max volume and play extremely loud, obnoxious noise all day everyday without a care in the world. Because for whatever reason, during these times they forget, or choose to ignore, that headphones exist.
I have mentioned it before because it bugs the hell out of me because there's almost never a quiet moment but of course nobody cares and carries on. I'm sick of hearing screeching from the crap they're playing. There's an issue when you can be on the other side of the house, with earplugs, behind a door, and still hear it.
So my plan was to lower the max volume on their phones and act as though an update or bug lowered the loudness. I know there are apps that limit volume but the volume bar gives it away that their phone isn't on the maximum. So they'd ask me to fix the problem, thus ruining the point. So I am wondering if there is a way to limit it but have the bar still reach the end and act as if the phone reached max without them realizing? So I can pretend it's a hardware issue.
