Yes, I did the same thing you did. I was successful with other updates--just not the DSP one which is what I am stuck on. Per my original post, I have two Cinema 1200s, both that display DSP version 0.0 and both un-updateable no matter what I have tried. I had hope with the web interface--but no luck. At least I have an error message indicating that there is something wrong with the update file itself OR the hardware that interprets the firmware.

Thanks for the update advice to use the web interface. I am stunned why tech support doesn't offer this route instead of USB--much simpler. I tried the above method, and whilst straight forward, I got errors trying to update to either DSP 4.4 or DSP 4.9.m Both abort with the below errors. The errors are the same for 4.4. and 4.9, only the ISPBOOT.BIN filesize changes in the below output: [network_initializer] : Main thread sleep again ! Image invalid or corrupted. Not installing ... ERROR core/cpio_utils.c : extract_cpio_header : 518 : CPIO Header corrupted, cannot be parsed ERROR core/cpio_utils.c : get_cpiohdr : 48 : CPIO Format not recognized: magic not found [scan_ubi_volumes] : mtd6: Volume found : nsdk-rootfs [scan_ubi_volumes] : mtd6: Volume found : nsdk-settings Software Update started !

Hi, I wanted to share my story of issues with the Cinema 1200 soundbar. Long story short: I now have two Cinema 1200 soundbars that both don't work at all now. I have purchased one in October and have issues since day 1. I should point out that the customer service team have been very helpful and are clearly doing their best--however, there is clearly some firmware/fundamental issues in the Cinema 1200 that have not been sorted out. I would love to know how to escalate my issue to get this sorted out--so if anyone knows how I get more visibility outside of the Customer support team, please let me know (Can I email the CEO, a product manager, firmware engineer--anyone to help?) Here's my story: I purchased the Cinema 1200 in October from Crutchfield. Mounted it on the wall, everything seems great at first. I notice in the first week that sometimes the soundbar will just stop playing audio. Sometimes a reboot will fix it, but often when I turn it on it has a "high pitch whistle" and no audio. Usually off/on and reset and holding down the on button would fix it. I also had issues where occasionally, audio would stop in the center speaker and all audio would divert to the rear right speaker. Back and forth with Crutchfield, they said they needed 3 separate calls before they will replace it. I realized it would be faster to talk with Klispch. We did a bunch of trouble shooting over a week or so and eventually they agree to send me a replacement. Which does not arrive until late Novemeber. Around this time, I discover that it is Atmos content that is a common trigger (but not exclusively). Something like Bridgerton would cause a crash frequently, at specific scenes. Eventually, around the start of December I get my replacement speaker, so I set it up to test. Any atmos content would not play at all. The speakers would just crackle loudly and I would get bits of audio interspersed by quiet or crackle. I look at the firmware versions and see that it is older than my original one I purchased, so I figure it's just a firmware issue. I goto the Klipsch website and follow the instructions to a tee to update all the firmware (There are 3: DSP, Wifi and something to run if the LED is bricked). Two out of the 3 work fine (Wifi and the LED one). The main one, DSP, fails every time. Figuring it was an seperate issue with the replacement, I try updating the DSP firmeware on the old speaker. Now both speakers have DSP 0.0, play a high pitched whistle when turned on and play no audio whatsoever. I have now spent weeks with support, I have probably spent 10 hours flashing different USB sticks, following instructions and trying different combinations of "wait times" for the flash to work. Customer support even mailed me USB sticks with the new firmware installed (4.9(, but flashing would still not hold for either one. So now, I am waiting yet again for my call to be escalated to some technical team, it's now been 3 days since that point, and about 3 months since I paid $1700 for what was supposed to be the best soundbar on the market, and right now is a large paper weight. During the long wait for a replacement and all this troubleshooting, I can't even get my money back from Crutchfield because they have a 60-day policy. So I am in a pretty bad position, where I am out alot of money with nothing to show for it. Well, I do have video and audio recorded of these issues--it's not pretty. I'm not trying to cause a scene, I simply just want to have my Cinema 1200 to work. It's been a frustrating experience and I have gotten alot of sorry's from support and I know they are doing their best--but I need a product manager or engineer or manager form the firmware team to help. Or something.

I had the same problem: rear left speaker crackling. After powering off for 2 minutes (the whole system) it stopped. But clearly this is a common issue if at least two of us has experienced this. I just submitted a support ticket (i also have spotify issues: music stops for 2 seconds in the middle of almost every song).
