Any song with any kind of bass produced a crackling noise from the speaker.
Curious to see if the new one cracks and pops.

I know in new residential construction there are some different electrical codes and standards in place.

That points to a speaker defect and not a Trueplay driven issue that this thread is about.

Nonetheless...the new one should not behave the same way, Sonos does not need special kind of mains power to work, just the normal stable kind that is utility provided, as long as that means that old, and well established quality standards have to be met before a construction is released for residential use.
I have the exact issue of "popping" on bass for my Play 1's (2 of them) and Play 5. Is there any actual answer on how to fix this yet??

I have had this problem for some time, two Play 1's but only one experiencing poor bass response or 'clipping' even at relatively low volumes. This happens whether using TruePlay tuning or not and with identical EQ settings on both units. Not sure if this is the case for anyone else but the solution was very simple for me. The unit affected was on the worktop in the kitchen, within close proximity to the power socket. As such I coiled the power cord and cable tied it in a nice neat bundle out of sight behind the unit. It occurred to me that the only difference between the kitchen unit and the unaffected living room unit was this cable arrangement. I've uncoiled the cord and done another TruePlay retune and hey presto, nice deep bass (deep for a Play 1 anyway) with no clipping/popping even at much higher volumes. The units now seem very much aligned in terms of sound quality. I assumed units like these would be shielded from electrical interference but clearly not where a cable is coiled and so close to the rear of the unit. Hope this is of some help to others.

How strange! I have several Play 1's (although bonded in a pair with a Sub) but the one which has the distorted bass issue has an identical set-up to yours. I tried your trick and amazingly it has sorted the issue! I uncoiled the cable and moved the speaker away from the socket and did a retune. After the retune, I coiled the cable back up and moved the Play back to its original position and it continues to play without any distortion. Thanks for the advice.
Just to add to the thread, I have always had the bass distortion issue with my Play 1's. I have had 4 Play 1s over the past 3 years and currently own 2 units which were purchased about 3 months ago. The speakers were / are positioned in different ways and in different locations. Trueplay tuning (done it many many times) always resulted in bass distortion (bass popping and clipping even at low volumes). My only solution to the problem was and remains: Turn off Trueplay. I do not get bass distortion once I disable Trueplay on the Play 1. This is a shame of course because Trueplay works great on my Play 5. I am using the manual EQ to tweak the Play 1 sound.

I find the default Sonos sound (Play 5 Gen 2, Play 1) to be very bass heavy anyway. This is exacerbated if the speaker is close to walls but the bass bloat remains even if the speaker is placed well away from walls and in big rooms. Loudness (on by default) adds to that problem. I managed to get a more balanced sound by reducing the bass by quite a few clicks (between 3-5).

So to summarise, like others, I have always had the Trueplay bass distortion problem with all my Play 1 speakers (past and present). I have accepted that unfortunately this is not going to be fixed but I can achieve good sound by disabling Trueplay and manually tweaking the EQ.
Just a quick follow up to my previous message.

Good news: I have managed to use Trueplay on the Play 1 without resulting in bass distortion. I am not sure why it works after my previous attempts. I had not tried Trueplay for 2 months but tried it again last night and it seems to work. It reduces (to some extent) the bass bloat which is the default Play 1 sound but the real magic is with the midrange and vitality of the sound. The bass bloat need further manual EQ adjustment after Trueplay (2-3 clicks additional reduction in bass) but the great news is: No more bass distortion :-)

I love the resulting sound.

My advice is to try again and to repeat the process a few times. Also, if you have any case (no matter how minimal) on the iPhone try removing it.

Cheers
I too was having bass distortion issues on my play 1. Today I decided to try turning TruePlay off and then on again and my issues have vanished. Not sure why this worked, but it worked for me.
Mine does the popping sound with Trueplay turned on or off, it seems to slowly raise the bass levels then it pops and turns the bass down, it then slowly raises bass again then pops again, I have already submitted diagnostics a while ago, but sonos couldn’t say what was wrong, we just have to put up with it I’m afraid, shame really because when the bass raises it has a real nice sound
Yes it does, I was curious if it did it or not, so I moved it. I have given it to my daughter now as they don’t care what the sound is like, lol
I am new to Sonos. I bought a total surround sound system PLAYBAR/SUB/2-play 3’s/ and a ONE. The TV room was set up with all speakers except the ONE, and it sounds good. The ONE is set up portable, and it has the bass distortion everyone is referring to. At low volume the speaker sounds decent, but with any volume or bass, it distorts horribly. I noticed the distortion within 10 minutes of setting it up.
I just bought the system to replace my JBL extreme (which sounded great) and an cheaper Samsung home theater system (which wasn’t very good). The Alexa feature is nice but the distortion for a $200 speaker is unacceptable. Considering you need to have two to sink in stereo I am glad I bought the two play 3’s (so far no distortion). I may just return the ONE and get a DOT and use the TV room setup and the JBL extreme as a portable.
Based on others comments, not sure the ONE or play 1’s are worth it. I know others have positive comments, but sure are a lot of similar issues for a suposidly high sound quality speaker.
There is clearly a problem with Trueplay and the Play 1. I exchanged my previous Play 1 with a new one, only to find Trueplay creates the exact same bass pop issue. I don't understand why Sonos doesn't fix this problem in the next software update. Without Trueplay, the Play 1 sounds muddy and flat. No matter how much you adjust the Treble and Bass. Trueplay reduces that mud but gives you the bass pop. I couldn't recommend the Play 1 to anyone.
This problem would be fixed if Sonos gave the customer a comprehensive EQ not just a Treble and Bass. It is embarrassing that the Play 1 potential is locked. Please let us have a proper EQ.
Trueplay still broken on the Play 1 in this latest update. 😞

Has anyone found a solution for this yet. I just bought a play 1 and came across this problem. If no solution is there a walk around?
I have the same issue, just bought my first play one to see what it was like before buying a second.

Same for me on a new Play one. Bass blowing out after Trueplay tuning.

My diagnostics number is 8308181.

Playing Breathe (Nora En Pure remix) - SeeB, the bass blows after each beat. I've tried re-tuning but the only way to reduce the bad effect is turning off loudness or trueplay.

I’ve had the same issue on my kitchen play 1. Rang support in Australia 3 times over the last 6 months about it. Each time I rang I was told “wow we have not heard of this issue before.”

The second and third calls were taken by the same guy..... :/

Sonos don’t care. They already have our money.

Oh and the new sonos one has the same issue. Just heard it first hand in store demo.

I'm just curious if everyone whos having this problem here if it's under these two circumstances: 1. Trueplay on 2. Volume just under the middle of the volume slider? I'm really trying to figure this out as I love the sound of these speakers when I don't experience that clipping noise. Iv moved my play 1 to my computer desk and it plays very well until the volume reaches near the middle of the slider. and if you go over the middle it seems to be ok as well. We need to keep on the team about this issue.

We need to keep on this issue. It's like buying a new car that comes with air condition but it just blows hot air if you turn it on halfway. Then the car company just keeps telling you that they have never heard of this issue before and that you should just not use the air condition for now. This issue was first posted back in 2015 and it's still present today.

Yes, i see the same thing one dance tracks. I've managed to curtail it by running with loudness and dropping bass to around 35% on the slider. It goes when i turn up past halfway point but i guess that's the curves cutting bass as volume grows.

Just been on with Sonos and have to say after a reset and retune it's slightly better. It's still there, but not as bad. Tomorrow I have to retune again but focus on where I normally sit, not the whole room.

Were you on the phone with them? Keep us posted. They want me to give them a call, hopefully, I can find the time next week.

Any luck?
“retune again but focus on where I normally sit, not the whole room.”

I tried this right now with my sonos one, and much more happy with the sound. Just try 🙂

Can you guys please tell me what music services you were using when you got the popping clipping noises from your speakers?

This thread is 2 years old and there's still no fix? I'm having the same problem with a stereo pair of Play:1s I just got for my kitchen, a bass pop/whelp is so bad, it makes it unbearable to listen to. Like others on here, if I turn Trueplay off, it seems to basically completely go away, thus, clearly not a hardware issue (but the remaining EQ settings doesn't quite get the overall sound quality/other frequencies back).

I'll note that I've had a stereo pair in my bedroom for a year and never had a similar issue. I'm wondering if it's a room/speaker placement issue. My kitchen is smaller and shaped like an L, and thus the Play1:s are placed perpendicular. I really hope Sonos has actually been testing Trueplay in all sorts of room configurations, I'd be surprised if they can't replicate the issue. For the time being, I believe they should update the software to allow "fine tuning" after Truplay. The bass and treble sliders simply don't cut it. Oh I'm playing from my own music library, so it's not a streaming music issue.
