Worked on my 9130. Thank you.

Just opening the driver manager worked on my machine. Thanks for posting this..

THANK YOU!!!

Windows 7 in 2021 ..lächerlich

I assign shortcut for killing pulseaudio "pulseaudio -k" on the key "Mail". I just press the key every time when it happens.

It did not work

hardware issue ... used the cable instead of the wifi and it went away

IT DOES WORK!!!! Amazing solution, man. I added the driver manager to my startup. So it's a driver issue. Man, man. Thanks so much.

Thanks for your research. This has been my main complaint about Mint. I will say I have had this issue with both Kernel 5.3 on a very old system and in a newer B550 board system on Kernel 5.13. My workaround was to pause whatever audio is being impacted (usually a video) and to mute whatever tab causes the crackling. Discord (sound notifications) have been an issue was well as certain ads. After muting the offending tab I would refresh the tab I was listening to and that fixed it temporarily. I am guessing this is doing the same thing as restarting pulseaudio. I will give your fix a try next time this occurs.

Thank you.

Outstanding! Thank you so much for your help! It may also help to run pulseaudio -k as your logged in user... if you can't reboot. I hope that this issue is cleared up for everyone.

Thank youuuu!!!!!

Thanks a lot mate! I thought the problem was that my phone was too close to my speakers.

hey! I did it and it worked but I still have the self diagnostic: restart in 15mins error. Do you have any additional idea how I can fix this? :)

Hey I've had this problem for many days now. The only difference is that I don't have an eternal speaker and it only plays the buzzing sound at high or low frequencys.

Your information also helped me solve the problem, thanks

same issue on G6 server

This fixed my problem immediately! Thank you so much! :) My printer: Brother MFC-9140CDN

Thank you for sharing this. I've been testing the audio for one week now and no cracking sound so far 😀. This problem used to be really annoying

Hi, this PERC only works on AMD PE servers?

Mine does this when the first milk drink is made and then it buzzes even on the hot water. After it cooled down, it could run again.

POSSIBLE FIX!!.. Had the same/very similar problem on a PrimaDonna S DeLuxe 26.455. Checked out the replacement part suggested (thank you Knut Midtveit :) and downloaded the diagrams on the suppliers page. Make sure you have the correct model number - there's loads of delonghi B-2-Cup machines but (I'm sure) most are built on pretty-much 1 of 2 or 3 platforms with slightly modified externals. There's actually 3 solenoids inside these dual-boiler machines, thankfully the one that requires attention is near the base of the machine, despite being pictured higher-up on the exploded view. If you put a meter accross the two power cables you notice it only becomes active for 'Steam' function and Descalling. !!!!!! WARNING - It's MAINS POWERED 220VOLTS A.C. !!!!!!! Anyway these solenoids are east to dissasemble by rotating the bolt on the top of the solenoid & taking the coil off. You can then remove the plunger barrel (just pulls off after removing the plate held down by a couple of Torx screws). I cleaned it thouroughly - removing what looks like a thin layer of rust on the sprung plunger (the actual valve) and Voila!!! it works. Guess I could have bought a replacement instead but the cleaning has made it work again. For me it means the machine Descale Cycle which was the issue I had is now completing OK. I've got pictures if anyone wants but don't know how to post them on here (that's irony for you!!!).

This stupid scammer has called me before and he is stupid. I make fun of him because he is just a silly scammer.

I just replaced the solenoid valve on mine. Cost £12 from eBay, all is well!!!

had the same problem.... you need to remove the ram & processor & put them back.....

Hi, I opened the back cover and sidecover and found the noise coming from the solenoid valve. Order replacement here www.4ourhouse.co.uk/solenoid-valve-2v/product.pl?pid=2987251&query=Delonghi+Solenoid+Valve+2V Mounted it now and the sound is gone, my wife is happy again :-) You need kind torx bit with a hole in it to unscreew the 5 screes at the back, the back cover can then be removed. The Left hand sidecover, same side as milk will can then be slided back and out. Two screes are holding the solenoid valve and need to be unscreewed from bottom of machine

I have a Delonghi ECAM 23.450S that had this problem also. When trying to froth the milk with steam, the frothing milk & steam mix would splutter to a halt, then the machine would buzz loudly. It also would sometimes display “Grounds Too Fine, Adjust Mill”, followed by”Insert Water Spout” First of all I replaced the Steam Heating Element part No. 7332196700, but this did not fix the issue. Next I replaced the Outlet Coupler (the nozzle you plug the milk container onto) part No. 7313217291, but this also did not fix the issue. Finally I replaced the Discharge Solenoid Valve part No. 5213218311, and this fixed the problem. This solenoid valve is upstream from the Outlet Coupler, and supplies Hot Water or Steam to the Outlet Coupler (not to be confused with the vent solenoid valve part No.5213218421). This was an usual situation where this solenoid valve would function OK delivering hot water, but would fail (and close) when trying to supply steam. It looks like the steam pressure was enough to force the valve shut, even when energised, and cause it to buzz loudly. I have put together a document including pictures and a flow chart to show how this all works, which I can email out if anyone is interested.

hehe... 'I'm on openSuse.org now"- still nothing. Brilliant!

Same problem. Mine is a Magnifica S ECAM 23.450 SL. Started happening a few months after warranty expired. A solution would be greatly appreciated.

24 minutes! WOW... they're getting really good at that.

I have the delonghi cappuccino s, same problem:( would be great if you share a solution

Which distro are u using?

lol when chrome "crashes"

your English is good, and so is your choice of operating system

I love your accent Claudio! Where are you from? Switzerland? Great job with the scammer.

hehe serves the scammer right:)

lol those scammer asume all that actually call them are idiots when it comes to computers:)

well that scammer doesnt really sound like he knows anything about computers. If he did he should have atleast recognized suse as linux os if norting more.

Great job, I did the same, usually i run windows 7 on Virtual Box and waste at least an hour of their time, recently Installed tried Linux with them, and after long convo installed TeamViwer like they asked, and they logged on, only this time its LINUX lol (antiX lightweight distro) will upload video pretty soon. Every minute counts to waste their time, thats means less chance of some people get scammed by these guys.

So after the 5th time I gave the machine for repair, the shop finally told me that my coffee machine is "not repairable". The following pieces were replaced from the shop with original Delonghi replacement pieces: - Valve (Ventil) through which the milk is pushed out (twice) -> since this was replaced, the problems got worse - Another piece which "burnt" (so I was told... whatever it was) - Heating unit Now the machine still has the same problem and the repair guy is left clueless. The next thing to replace, according to the repair guy, would be the electronics, therefore the whole machine. This is where it's time to say good bye. The machine made really good coffee - but only for a bit more than 2 years. Right after the warranty was over... That's not long enough for the high price of the machine. I'm very disappointed by this Delonghi product.

Exactly the same problem on my 26.455. Any luck yet?
