MagniFi Max SR - Surrounds Popping (despite software updates)

Same problem here with the popping and crackling from the subwoofer. I exchanged my first purchase thinking i had a defective unit but the problem remains. Not a happy camper. WTF Polk? At least acknowledge the problem.

Same problem here, loud chirping and popping sounds from the rear speakers. I was thinking it was an interference issue. So I purchased a power conditioner and plugged everything into it. Unfortunately that did not fix the issue. May just do an exchange at this point...BUMMER

Use Google Home app, open Device Card for soundbar and tap three dots for settings. Latest is version 79.

Since they're aware of a problem, and working on some update (beyond v.79) I remain optimistic this will get corrected. When all "systems are go," the Max SR sounds really good. A chirp-free patch will make my dog really happy too.

HI, just purchased these before I saw this forum. A few questions:

1. If I don't connect it to the internet, will that prevent it from installing newer firmware that caused the popping issue? Or is the issue right out of the box?
2. I saw some posts that changing to 5G wireless seemed to help the speakers not pop, has anyone had any luck with this?

The large majority of Max SR owners have no problems with the surrounds and subwoofer making occassional noises and enjoy the sound and performance completely. In some environments there can be interference between other wireless devices which result in popping sounds coming from the surrounds and the subwoofer. The good news is that Polk is going to be able to solve this problem via a firmware update which they are in beta testing. Anyone who is experiencing this kind of problem can contact me via PM and I will work with Polk to solve the issue.

I have random popping from the sub and chirping from the surrounds. Fw79

I also have crackling noises from the sub (on 2nd one now, dealer replaced whole system) & popping from the surrounds. I experience this manly when playing Blu Ray & DVDs some of which were brand new. TV & Netflix are OK most of the time although noise from sub can still be heard & is distracting. Tried turning off WiFi & devices in house & still experience issues. I suspect it may be a specific signal from source causing pops rather than WiFi but can’t be sure. Such a shame as sound is terrific when all working as it should but considering the cost it’s disappointing. Several friends/relatives have been put off buying one when they have heard this for themselves. Any update on the new firmware? I’m also on version 79 at the moment.

THIS POST MIGHT APPEAR IN OTHER THREADS REGARDING MAXSR PERFORMANCE

A few weeks ago, Polk asked me if I'd give their beta v85 a try.

(I don't think I signed an NDA- ah joke)

There were three of us that had the new software pushed onto their MagnifiMaxSR.

After three weeks of regular use, I've told Polk that there is a significant improvement in overall performance. NOTE: I had never experienced any sub problem with connection or irregular performance.

The harsh momentary burst of "chirp" (of the rear) has been eliminated. The faint pop in one or both (sometimes alternating) rear speakers has been dramatically reduced. Occasionally, I hear what sounds like a distant firecracker, but nowhere near as bad as it had been. There is still some room for improvement with the pop in the rear.

What I've come to feel about this whole issue is, that it is NOT an issue of transmitting signal from bar to remote speaker, but is related to some anomaly in the actual content or source of the content.

Example 1: After v85, watching a program on cable (xfinity xg1v4 box) there was a bright open caption and the rears gave the faint pop. I replayed the scene and it popped again at the same place. I have my devices connected to the Sony and then the ARC from the TV to the soundbar. I re-routed the cable box right to the soundbar, played the same scene and it popped that way too.

Example 2: After v85, while playing live "Homeland," which had no issues, all was fine until the credits. When they put the corner box of what's on next week, the rears started chirping quite a bit. Many short bursts. The oddity here is the program is in DD, yet when they play the next week clip, the audio from that material is almost inaudible. My feeling is that next week clip is in 2 channel, and somehow that is **** up the 5.1 the show is transmitted in. This 2-ch over 5.1 could be one of the things triggering the remaining infrequent chirp.


BELOW IS THE EMAIL I SENT TO POLK;
MagnifiMax SR Performance After Update v85

I received the MaxSR just after Christmas and have been using it regularly since. My TV is the Sony 75Z9D, and I use the ARC from the TV to the soundbar.

My cable provider (xfinity) installed their newest XG1v4 4K box when I got the TV mid 2017. I use the inputs on the TV for cable, Roku 4K device and Bluray player. The soundbar receives those devices through the (HDMI Out/TV) ARC input. Two other devices are hooked up to the soundbar, a Sony 4K player in HDMI1, and the Optical In from the Roku, so I can play Roku music channels without powering on the TV.

After making mention of the pops in the rear speakers (which I've described as sounding like distant fireworks) and a loud digital chirp, that lasts only a fraction of a second (also from the rear speakers,) I was contacted to beta test the version 85 software.

First off, the elimination of the digital chirp has been significantly improved. The faint pops, also less frequent, still seems to be an issue,

Before the update, the chirp occurred nightly for one broadcast I watch. ABC World News, a network half-hour program which is carried on my local ABC affiliate, chirped loudly, several times during the broadcast. Since the update, that is no longer a problem on that program. It had to be a problem with the way the program was being transmitted out of New York and received here in Palm Beach, by my local station.

When watching "Homeland" live, this past Sunday, the show played with no audio issue, but then during the closing credits, when they run a preview of the next episode (in a small corner box over credits) the rear speakers chirped several times. The show is 5.1 DD, and the preview at the end is in 2 channel stereo.

All my cables are certified 18Gbps, new when I got the TV last year. I switched the ARC cable when the audio problem became regular. There was no difference with a changed cable.

Apps like Netflix and Prime, both 4K sources from the Sony TV, (also on the ARC cable) play without chirps, but do have occasional rear channel popping.

Overall, the v85 is a major improvement in solving the issues. If I experience an occasional, faint, single pop, I feel it's something I could live with. Maybe other people's comments might steer you closer to completely eliminate these glitches.

Thanks for the update LeeSoFL fingers crossed they’ll roll out the new version to everyone else soon.

Agree with your comment about the popping not being related to sound bar transmission to sub/surrounds & more to the system handling (or not!) certain sounds/signals from content . For example experienced rears popping the other night at the end of the opening scene of Skyfall just at start of soundtrack. Loaded DVD which came free with the Blu-ray & had pops/interference at exactly the same place which would seem to rule out damage to disc or intermittent loss of signal from the sound bar or WiFi interference.

Anyway thanks again.

Polk is aware of the problem and is working on a solution as part of a firmware update. I don't have a specific date, I'd approximate it within the next seven to ten days. If you'd like to be a participant in a beta test of the update send me a PM. In the meantime if the popping sounds are too distracting unplug the surround speakers.

Keep in my, what comes out of the front channels is not the same sounds and signals in the rear speakers

I probably didn’t word my last post very well. To clarify - In my case having turned off all wi-fi in house & not being near an adjacent property I don’t believe the issues are in the main caused by wi-fi/radio interference but rather the soundbar unable to transmit certain signals to the rear speakers from source which then causes a pop. I have been able to recreate popping by playing the same part of a film Skyfall) on both Blu-ray and DVD. Some discs will play completely fine time and again. I don’t know about the sub issues or if that will be resolved.

I am having the same issue - chirping / interference in the rears and sub popping and crackling. I have replaced the system, disable all wifi in the house, added a power conditioner, changed cabling, tried multiple sources. Nothing works. I really hope the firmware update when it is available can fix the issue.

I haven't had the chirp since 85, but the popping still continues to be a serious issue. On the Google Home app, there is a "help improve" box covering the Polk software version info, so please let me know if anything newer than v85 comes around. Do any of you have that problem seeing what version you're running??
